Me, when someone shows me a plot without axes labels

I am receiving invitations to predatory/fake conferences every day, but this one feels like a personal burn 😅🔥

10 years after its founding, driven by the energy, enthusiasm, & dedication of the community @quantum-journal.bsky.social quietly published paper #2000 some days ago. At least I think this is a big deal, big shout out to the founders & all authors, reviewers, editors, board members & contributors!

Some quantum info researchers are reluctant to learn about non-CPTP maps, but are ultimately left with no Chois.

QuOI is happening?

Over on LinkedIn the spirit of the season is spreading with a joyous round of pre-holiday bragging about publication metrics 🎄

Was an honor and pleasure to serve as handling editor for this paper, not just because it was a very nice piece of work, but also bc I enjoy good puns and pop- (or in that case, rock-)culture references (admittedly, also the bad ones), not sure if the authors noticed mine in the decision letter

Social(-media) experiment: I posted the same blurb on our new research paper on Bluesky and on LinkedIn. Apparently many more people from the quantum bubble on LinkedIn (~5 times as many reactions), but actual responses there mostly nonsense and people trying to plug their business

Quantum networks might one day enable more secure options for communication and distributed computation and are therefore currently a hot research topic, one which presents many challenges: One is the on-demand distribution of quantum systems that feature genuine multipartite entanglement (GME). 1/8

Is it just me that finds it weird how ingrained it is in science that research groups identify as "The PI's-last-name group" as if their research & research interests were entirely determined by the PI? To me this feels unnecessarily adhering to authority and fostering cults centered around PIs.

Hier übrigens eine sehr gute Einordnung, was die "Antifa" ist - und was nicht Von @nhoraczek.bsky.social

You want to submit/have submitted your paper to Quantum and would like to speed the editorial process along? Suggest reviewers! You know the field and who has the expertise. But keep in mind who is likely to have time. Famous senior profs are not likely to reply to review requests.

Serious conclusion of yesterday's 1-hour research meeting: we might need anti-banana masks

I might have to reference this excellent blog post in my next QC class...

He's not wrong

Glad someone took the time to debunk the (obviously nonsensical) claim that Bell inequalities could be violated w/o entanglement. It is astonishing (to say the least) that this claim was made by experienced authors & that it passed peer review in the first place, does not reflect well on the journal

"our results indicate that academia pays a price by focusing attention and resources on superstars" Nice to see this supported by data analysis, now. H/T: @cxdig.bsky.social www.nature.com/articles/s41...

DEN Artikel muss ich teilen, weil ich ihn wirklich sehr gelungen finde. ☝🏼 taz.de/Felix-Baumga...

Given that I recently saw an advert like that, I wonder, are students really interested in starting a PhD under the premise that they work in one country while the supervisor quite obviously works in another? Is the supervisor going back&forth? At least my students want to meet at least once a week

Dass die neue deutsche Bundesministerin für Wirtschaft "Reiche" heißt, ist mindestens so lustig, wie der Umstand, dass der ehemalige österreichische Bundesminister für Gesundheit "Rauch" heißt.

After many years in academia I might have become a bit cynical about certain structural problems and I have found myself disappointed by colleagues and their behaviour on many occasions, but today a colleague managed to show me that decency, honesty, and integrity are not dead yet in academia

Ziemlich erschütternd, was es 2025 noch für Männerbünde mit elitären Fantasien gibt. Gibt es eine öffentlich zugängliche Liste der Mitglieder?

Genuine multipartite entanglement—GME for short—is a type of entanglement that—much like a certain Lovecraftian cosmic entity that took a break from napping at the House of R'lyeh to make a guest appearance in our paper arxiv.org/abs/2504.21076 —is even weirder than regular entanglement: GME … (1/6)

Am very happy to see this paper by the power duo Klára and Olga out in Quantum: We set out to study the activation of genuine multipartite entanglement (GME) in the continuous-variable setting. On the way, we discovered a treasure trove of results... (1/3)

Entanglement is a form of correlation that is "stronger" than classical correlations in the sense that correlations are equally strong in infinitely many pairs of bases. But how strong do correlations have to be in any arbitrary pair of bases to conclude that the system is entangled? (1/3)

Pleasure was all ours, Phil, pleasure was all ours!

Maybe it's just me, but I find it difficult to take an "international" conference seriously if some of the organizers and/or members of the scientific committee are also "invited" speakers, and, independently of that, if all of these three groups exclusively consist of men.

Not that this was really unclear.

My team knows me too well 🖤🐙

Been here 5 minutes and nobody posted a screenshot of their google scholar, so far, so good.

Hello quantum blue-sky, hope this will be(come) the experience that quantum twitter once was!
