Hi, quantum researchers and authors! Some friendly, informal, totally non-binding advice from your Editor in Chief at IEEE Transactions on Quantum Engineering (TQE). (Written in November 2025, posted here with small edits June 2026; my term as EiC will expire in March 2028.)

The number of submissions to TQE has been climbing rapidly this year. (Hoo boy -- I wrote that in 2025, and it's double so in 2026!). Thanks to every who reads, submits to, reviews, edits, and produces TQE!  The professional IEEE staff are amazing, and the editors tireless at a thankless job, so let me thank them publicly here.

With the increase in submissions, there are also naturally more papers with relatively easy to fix problems that slow down my share of the processing, and in turn slow down the whole journal.

So, when submitting a paper, ask yourself three questions:

  1. Is my paper going to generate a "clean" report in the plagiarism checker?
  2. Is my paper going to be easy for reviewers to work with?
  3. Is my paper tuned for this journal?

If every submission was clean on these fronts, my workload would go down at least 20-30%, and stalls in the pipeline would decrease even more.

1. So what is a "clean" report in the plagiarism checker?

Well, the checker returns a number, expressed as a percentage, that is very roughly the fraction of the paper for which it found matches with other materials in its stash (which includes almost everything in English on the web, not just other research papers in journals).

No paper ever written returns zero, so it's always a matter of making a judgment call.  No one is going to ding you for boilerplate or generic text like "A graph G={V,E} comprises a set of vertices V and a set of edges E," but that's a human call, not something the system can automatically handle. If a paper has a moderately high score, I often set it aside for a deeper look later, slowing the movement of your paper through the system.  So, if your paper will have a high score, please explain why in a cover letter.

The checker will pick up arXiv and other preprints as well as shorter IEEE conference versions of the same paper. Those are entirely legit, but I have to check; calling them out in a letter smooths the process.

If your paper draws on your own previously published work, YOU MUST SAY SO in a cover letter, and if this paper is an extended version of a conference paper, also in a footnote in the paper. i.e, "Portions of this paper previously appeared in x," or "This paper is an extended version of y."

In IEEE, there is no such thing as self-plagiarism. You are allowed to reuse your own work, with credit, of course. But a couple of issues come up: if the work is substantially the same, why bother republishing it? Explain what is new in this version.

And, as noted, there is the issue of copyright. PLEASE EXPLAIN THE COPYRIGHT STATUS OF THE PRIOR WORK. Without permission, IEEE cannot republish work where the copyright is held by others. If you still hold the copyright, or IEEE holds the copyright, we're good, but please tell me!

If you transferred the copyright to another company or organization, you also need to let me know, but we are probably going to ask you to rewrite it. If you really want to reuse the same text (or figure), it is your responsibility to get permission and make sure it is credited properly.

All of the above could have been written any time in the last two decades. The new twist is, of course, AI.

I'm not going to discuss a fully general AI policy here; that's for another time.

I get a lot of papers these days that have one sentence copied (generally but not always with one adjective or adverb switched for a synonym) from paper A, a sentence copied from paper B, a sentence from paper C...I don't think a human is deliberately copying from ten or twenty or even thirty separate sources. I'm pretty convinced that it's an LLM "helping" with the text, perhaps when translating from another language.

Of course more than half of the authors (and readers) of TQE aren't native English speakers, and using tools that help with English is legit. But you're still responsible for the final product.

(No, unfortunately, I don't have a pointer to a free plagiarism checker; building and running them is expensive, so they are paid services. If you're using an LLM, try asking it!)

To recap, anything that makes the report complicated slows down the process.

2. Look at your paper. 

I mean, LOOK at your paper, then ask yourself if someone who hasn't seen it before will find it appealing and easy to read, and therefore be favorably disposed toward the material.

Here I mean formatting and presentation: figures, text, and equations. (I don't mean the style. To submit to TQE, you don't have to put it in TQE style; we will review papers submitted in RevTeX, basic IEEE journal or conference format, ACM conference format, etc. The paper will have to be reformatted to TQE style later, though.)

A pet peeve of mine is figures with fonts that are too small to read. If I have to zoom in to 200-300% before the fonts become legible, there is a good chance I will desk reject the paper and ask you to redraw and resubmit. That delays your paper by weeks, and makes more work for everybody. Generally, the font in a figure should be the same size as the font in the caption. This problem is exacerbated if the figures are bitmap rather than vector graphics, which suddenly seems to be a problem. If I zoom in and I can't tell A from R, the paper is definitely going back to you. Not only is bitmap worse for print and scalability, it's also worse for searchability and perhaps for accessibility for visually impaired readers. Vector graphic text is usually searchable with ctrl-F, which can be handy. (Photos of equipment, of course, are okay in bitmap format.) Unless it affects readability, I generally won't send a paper back just because some plots are in bitmap format, but we will usually ask you to provide vector format for final typesetting.

This applies to equations, too; I sometimes get papers where the equations are bitmaps inserted from some other program. This is a pretty big no-no. Microsoft Word's equations aren't as pretty as LaTeX's, IMO, but they are fine when done carefully. Learn to use your tools.

Equations and figures should be numbered. Figures should have a caption and be floating, not inline. It's also friendly to compare your figures against recommended practices for different kinds of vision impairments such as the different types of color blindness.

I sometimes get papers that are just plain ugly: lots of changes of fonts and even font sizes, different line spacing sometimes even within the same page, etc. Except when it's REALLY bad, I won't desk reject a paper for that, but you can be sure it starts reviewers with a negative impression.

Check your references; particularly using BibTeX, different style files will leave out different fields, and I get a lot of papers with incomplete references. Clickable DOIs aren't required but are helpful, and if you confirm that they work then you save yourself the embarrassment of sending me an LLM-hallucinated reference.

Think about the process of writing a referee report. Help the reviewer (and later, the reader) as much as you can. Referees who get papers that require effort to read will put off the task, delaying a decision on your paper. (Such referees may also be less inclined to agree to review other papers we send them, on the assumption that handling our papers is a hassle. So you help everyone else, too, by submitting as sharp a paper as you can.)

3. Know your audience.

In particular, for TQE, papers that begin by explaining X, Y, Z and CNOT gates waste space and opportunity -- what a collaborator of mine calls "momentum" -- and you will lose readers. For the TQE audience, it's not necessary, and I don't want it 100+ times per year in our journal. This is also strongly correlated with newcomers to the field, whose work is often too basic to represent a publishable advance, so once again you start off on the wrong foot with reviewers. If there is too much of it, I will desk reject the paper and ask you to fix and resubmit.

Conversely, it is fair to assume that TQE readers are unfamiliar with the basics of e.g. machine learning or your problem domain and to include some background material. But if you are spending a lot of space on purely classical ML, have you submitted to the right journal?

The scope of TQE is, broadly, quantum computing, communications and sensing. I desk reject papers on quantum-inspired (read: classical) algorithms and on post-quantum cryptography (PQC), which deserves to be reviewed, read and used by classical cryptographers and systems engineers. I also desk reject papers that are pure physics, without a clear connection to the use of superposition, entanglement and interference (discrete or continuous) to surpass classical systems. True supporting tech such as classical cryogenic processors or cooling systems for quantum computers is very welcome, though!

In short, to repeat, know your audience -- the readers, reviewers and editors.

Let me reiterate, this is informal, friendly, non-binding advice to help writers create papers that are ready for the TQE review process.

Good luck to all authors, I love reading your work. You are working in the most exciting field right now, IMO, and we are all on the same side -- building, deploying and using the best systems we can. Stop me and say hi when you see me at a conference!

Spelunking CACM, Vol. 26 (1983): Japan's Fifth Generation


1983 marked the first quarter century of CACM itself. The outgoing Editor in Chief, Robert L. Ashenhurst, marked the occasion with a January special issue reprinting some twenty-one of the best articles from the archives. The paper copy of this issue must be a collector's item. Every article in that is worth reading, even today, and I'm pleased to see that my own spelunking found many but not all of those -- some fun things to go back and look at later!

In February, Peter Denning took over as EiC, and instituted many changes, including going to a full-color cover (hinted at on the January cover).

I didn't realize the Computer History Museum went back this far, but there is an article by Gordon Bell on a visit to a famous computer, organized by the museum (which he founded). "The Computer Museum's first considered priority is to save history, the second is to display it, and the third is to interpret its historic role," we are told. (Oh, wow, Bell was visionary enough to begin organizing the museum in 1968, and incorporated it in 1982! Thank you!)

Programming Pearls came in this year, under the stewardship of Jon Bentley. The first one, appropriately enough, is about one of the canonical CS problems -- sorting data stored on disk.

Doug Comer wrote a history of CSNET -- while the project was still ongoing! It mentions our Dave Farber, but only as a participant/performer.

Cook's Turing Lecture on computational complexity (a religious document, if ever there was one) led me to an article on Ultracomputers, a switched (indirect) multicomputer architecture that Schwartz claims scales to thousands of processors. Now that's vision! I like that Cook dedicated a section to space-time products. I'm curious what the modern thinking on this is.

But for me personally, given my own location and interests, the most eye-catching item this year was the special issue with several articles on Japan's Fifth Generation (which refers to the programming language generation for non-procedural, goal-oriented computation), the astoundingly ambitious, MITI-directed, top-down AI inference machine project. (This is the source of the image at the top -- is there no higher-resolution version available?) Articles included an introduction (Pamela McCorduck, who co-authored a book with Ed Feigenbaum on the topic), a somewhat separate article on Japan's software management processes (Paul S. Licker), a trip report (Ehud Y. Shapiro) on the Oct. 1981 conference sponsored by the government, and an interview on the US response (Rosalie Steier interviewing B. R. Inman). The trip report in particular is a gold mine of anecdotal history and contemporary views of the project, and features the memorable quote, "We may argue whether it is better to think and program in Lisp, or think and program in Prolog; but both are certainly superior to thinking in Lisp and programming in Prolog."

Today, the Fifth Generation is largely considered to be a failure as a project, but my opinion is much more nuanced, and at any rate it's complicated. That's all for another day.

Some Top Quantum Researchers in Japan

 A while ago, I created a blog post on quantum architecture researchers in Japan, mostly young ones and all very good. But I'm often asked more generally about quantum research and researchers in Japan, so here is a list to refer to. Note that it's ordered by Google Scholar h-index (in parentheses; taken when I wrote this blog post -- we're not being scientific here), which is almost inarguably a terrible way to do it, but I don't have a better method at hand. h-index and influence in Japan both correlate with longevity and probably with other factors such as gender.

A lot of other factors influence publications and citations, including ability to both publish and speak in English, but conversely non-native Japanese people are at a disadvantage in the gossip and influence network inside Japan, including hearing about and ultimately influencing the creation of funding opportunities, so there are plusses and minuses.

A few important people don't have Google Scholar profiles (at least not public ones), so I have dropped them into this list entirely qualitatively roughly where I think they belong. Note also that a few of these people don't fully curate their Scholar profiles and so may have either extraneous or missing publications.

(Todai = University of Tokyo)

(Yeah, when you get to the bottom of the list, I've included our own younger people, whom I know better than the younger people in other places. There are a lot more researchers with h-indices in the 10-25 range. I picked some I like. So sue me.)
(I think the top 20 or so on this list is a relatively complete list of the senior people in the field here; if I've forgotten anybody, let me know!)

Quantum Networking: Drafty Internet Drafts

Speaking as an individual contributor, not as chair of the Quantum Internet Research Group:

We have two new very drafty Internet Drafts out:

Timing Regimes in Quantum Networks and their Physical Underpinnings
Get the HTML version, which renders the figures, names and equations right.This one is intended to bridge the physics and the network engineering; there should be no design decisions in this document, but it should tell us how to use the physics to decide. It should be useful across all possible quantum network designs. In particular, I originated the document to help us understand layering in quantum network architectures.

Comments submittable as email (either direct to both authors or on the QIRG mailing list), or as Issues or Pull Requests on GitHub.

A Quantum Network Architecture
This one is the start of the description of our own quantum network architecture. Still very far to go. 

Comments submittable as email (either direct to all three authors or on the QIRG mailing list), or as Issues or Pull Requests on GitHub.

Comments very welcome on both documents!

These two are the start of what we expect to eventually be a full technical description of our network, spanning as many as two dozen documents.

Voluntary-Participation Surveillance Society and, oh, Little Things Like Aircraft Carriers

 Hilarious, inevitable, tactically troubling, and evidence of our voluntary-participation surveillance society. https://www.lemonde.fr/en/international/article/2026/03/20/stravaleaks-france-s-aircraft-carrier-located-in-real-time-by-le-monde-through-fitness-app_6751640_4.html

Strava is the app I use to record my bike rides; "everybody" is on it. It can obscure your start and end points if you don't want the exact location of your house identified, but if you're on a public app like this, you've already volunteered to share a great deal about yourself.

Warfighters are heavily warned against sharing opsec-sensitive info, and I've been told that modern briefings instruct them not to use Strava while on deployment. But it was inevitable that someone would forget. I'm sure the poor guy has already been disciplined and his shipmates won't let him live it down, for sure.

Dave Farber: Obituaries and Archival Materials



As you know by know, our beloved Professor Dave Farber passed away last month. The impact of his loss will resonate for a long time. Here is my list of articles about his passing, plus a few other things. Let me know if you see other articles that should be included. (Picture above: we cooked Dave turkey on Christmas Day, 2025.)

Perhaps my favorite quote from this set of sources is from Dave Crocker, in the Wall Street Journal:

His mind was, from what I could see, largely undisciplined, which is how he could make these connections so unexpectedly and usefully, but not always usefully. He would say things that put things in juxtaposition because his mind just wandered in various ways.

To me, that's high praise.

Eulogy for Dave Farber

[Photo is at Miyajima, Hiroshima, on Dave's 90th birthday trip: Keiko Okawa, Yukie Shibuya, Yasuo "tsucchy" Tsuchimoto, Kaori Suzuki, Rod Van Meter, Dave Farber, Jun Murai, Catharina Maracke]


 My comments from Dave Farber's funeral on February 13, 2026:

David Jack Farber.
Born April 17, 1934.
Passed away February 7, 2026.
Occupation: professor.

Those are the basic facts you will see on a census form.

Worked on telephone switching systems, built distributed systems, helped kick off important precursors to today’s Internet, served as chief technologist at the FCC, taught at five universities – those are the things you’ll read in the obituaries in the newspapers, and we heard about them yesterday from Manny, Jun, and Jiro. We heard from Manny about family, and Dan about Dave’s love of food and of Japan. (For those of you who didn’t join us last night, we hope to make the video available later.) And in a few minutes we will hear from Vint Cerf, whose career Dave helped shape.

Dave literally changed the life direction of several Keio students that I know of, and doubtless affected many more in ways I’ll never get to hear about. As a Keio faculty member, I’m deeply grateful for that. After Vint, we will hear from Taro, who is one of those whose life was changed.

So what more is there to say?

If I had to describe Dave, I would pick the 3 Cs: connection, clarity, and curiosity. Yesterday we talked about all three of these.  Dave's ability to connect people might be the true core of his career – it’s the thing that brought us all here today.  Dave was exceptionally clear in his explanation of things – and also saw clearly. Dave’s curiosity was endless; personally, it’s the thing I admired most about him, and he and I had long conversations about wide ranging topics (yes, including quantum computing), and it might be the core of his longevity.

A few days ago, while helping Manny clean up the apartment, we found a number of articles that Dave had printed out for later reading. I found a couple of things I had written on Dave’s desk – my blog entry on web3, and my class and research group policy on the use of AI. That's certainly an example of his curiosity.

Dave was not a particularly religious person, though he was proud of his Jewish heritage. G.G. was raised Greek Orthodox. I was raised American Baptist. One place where all of these things overlap is in the Book of Ecclesiastes (which, by the way, takes its English Christian name from the Greek). Ecclesiastes is known as Kohelet (which I’m sure I’m not pronouncing right) in Hebrew.

So, with your permission, I’d like to read a little from the King James Version of Ecclesiastes. It will be a familiar passage, and it’s one that’s often used in Christian funerals, at least in America, but it should resonate with everyone regardless of religion, I hope.

3 To every thing there is a season, and a time to every purpose under the heaven:
2 A time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted;
3 A time to kill, and a time to heal; a time to break down, and a time to build up;
4 A time to weep, and a time to laugh; a time to mourn, and a time to dance;
5 A time to cast away stones, and a time to gather stones together; a time to embrace, and a time to refrain from embracing;
6 A time to get, and a time to lose; a time to keep, and a time to cast away;
7 A time to rend, and a time to sew; a time to keep silence, and a time to speak;
8 A time to love, and a time to hate; a time of war, and a time of peace.

Dave knew all of these things. Dave did most of them rather frequently. We have done about half of these things just in this last week, talking about Dave and preparing for today.

Dave was much more than a colleague and mentor. Dave was my friend, and I will miss him.

My condolences again to Manny, Mei, Carol, Nate and Sam. Thank you for sharing Dave with the rest of us. May his memory be a blessing.

Go in peace, Dave.  G.G. and Joe are waiting for you.
