@mvscerezo please boost the original post so that Marco can more easily connect to people on qubit-social, etc.

Let us welcome @mvscerezo to Mastodon! Please to have Marco here and look forward to reading your posts

Hey there, Mastodon!

We're planning to have a portable recording kit at . 🎙️ Who should we talk to while we're there?

Please share this widely and let us know all of your suggestions - we'd love to know who you'd like to hear from!

I am also pleased to meet many younger people in the field whom I have not met yet. Here is the program:


This workshop was supposed to take place in Dec. 2020 and then got postponed until it could be held in person.

I will be very pleased to land in Singapore after a long journey from Ithaca (currently in Tokyo airport). I'll be there at the Quantum Resource Workshop quantumresources.science/ next week and looking forward to meeting up with colleagues and have intriguing scientific discussions.

The giant, Goran Lindblad, has sadly passed away:




I was fortunate to have an opportunity to meet him in his office in Sweden in spring 2019 and talk about the data-processing inequality for quantum relative entropy, one of his major contributions and inspirational works.

It is so relaxing to enjoy a social network without being bombarded by constant advertising and trivial nonsense.

The purpose of this toot is to follow up on an observation of @anuraganshu made at twitter.com/AnuragAnshu4/statu, regarding the main claimed result of arxiv.org/abs/2211.13372 (Eq. (3) therein). In the attached image, it is shown in a few lines that Eq. (3) of arXiv:2211.13372 is a consequence of weak monotonicity and two applications of the data processing inequality of quantum relative entropy. Tagging @letonyo and @LudovicoLami

@markwilde QIP had inherited from CS a fetish for complication. It is our job as reviewers and PC members to fight the fallicy that simple-->trivial and complicated-->deep. We know that at the heart of our field lie simple and deep truths that we're still discovering. Articulating the value of this simplicity is an important project.

Call for papers for AQIS released on Nov. 25 and conference to take place just three weeks later on Dec. 17-18:


No contributed talks and invited talks and posters only. This wins the award for shortest time between call for papers and conference dates. What is going on?

Anyway, this post is intended in good fun. I understand that the QIP PC has worked hard this year and has a difficult job of selecting very few, among many, submissions to be talks...

Maybe it is shameful for me to admit it, but I actually like sitting in a QIP talk and understanding something of what the speaker is saying :)

this year's interesting rejection report:

"I like the simplicity of the results and the derivations, although this could be considered an advantage or a disadvantage for acceptance. I am not sure about potential broad appeal as everything is elementary."

Congratulations to the authors of all talks selected for inclusion at !

In order to diversify the field, the University of South Carolina has introduced the "Bridge to Faculty" program, where underrepresented early career scientists become 2 year postdocs and evolve to tenure track faculty. sc.edu/about/offices_and_divis 10-12 positions will be given. If the math department is granted a position I will post the announcement here.

New paper on #arXiv!

Imagine you're given a box that's supposed to produce some unknown qubit state \(|\psi\rangle\). While it mostly works, it occasionally fails and outputs the orthogonal state \(|\psi^\perp\rangle\). How can you combine several outputs of such a box to obtain one reliable copy of \(|\psi\rangle\)?

We call this problem "#quantum majority vote" since the goal is to find the majority state from a list of unknown quantum states.


Peter Shor will give a talk "On the development of quantum error correcting codes" on November 30 during the memorial for Roman S. Ingarden which is organized in Poland. kcik.ug.edu.pl/en/roman-ingerd

@markwilde +1 from me too, LaTex support would be great. @alireza what do you think?

@markwilde To this I would add: consider adding a page number, unless the result or equation is very easy to find.

"As FirstAuthor \emph{et al.} note~\cite[pp.~7--8]{AuthorInitials-2018}, ..."

"By the Very Important But Rarely Used inequality~\cite[Eq.~59, p.~123]{ThatOneBook}, it follows that..."

For me, one of the most interesting aspects of joining Mastodon quite recently was to discover many new people in quantum information whom I had not seen or known on twitter. I think I had not been discovering new people on twitter because I stopped expanding my network there and simply continued following the same group of people I had always been following for the past 7 or so years. Of course, the QIS field has changed a lot during this time and many new people have joined it.
