Hi, I am here! Will mostly post about Quantum Foundations/Computing and Quantum Music.

Bob Coecke @coecke.bsky.social · 16d

100.000 hours of recordings, including:
Maths/CS: Grothendieck, Atiyah, Lawvere, MacLane, Eilenberg, Cartier, MacIntyre, Dana Scott, Kreisel…
Physics: Penrose, Hawking, Wheeler, Ashtekar, Ward, Geroch, Sciama, Salam, Finkelstein, Bohm…
Philosophy: Popper, Quine, Dummett, Wiggins, Badiou, Redhead…

In four weeks in NY I will be talking about quantum-enabled responsible AI.

A few days earlier in Toronto-Fields and a few days later at Perdue Uni too.

…in Cambridge.

That actually happened in the late 90’s to myself and a mate, when looking for a loo in some college. Porter could not believe that we were scientists at a conference.

Not only at the athletics world cup in Tokyo are new world records set. This is for our H2 quantum computer.

Mike has done butt with no success.

One of these things where institutions are not helping…

Bob Coecke @coecke.bsky.social · 29d

Surprised me too a bit!

Also, if you look at the history of new technologies, e.g. classical computers, artists are always typically among the 1sts to make some use of it. Christopher Strachey, father of Oxford Computer Science, was a pioneer here. www.bbc.co.uk/news/magazin...

Listening to the music of Turing's computer

Some 65 years after it was made, earliest known recording of music produced by a computer has finally been restored.

That's why people invented calculators, since violins and the likes were never particularly good at arithmetic. That said...analog waves can factor pretty efficiently! ora.ox.ac.uk/objects/uuid...

ZX-calculus is complete mainstream now in quantum industry...Wouldn't call that status quo. I am writing something too along these lines, but going back to the pre-Socratics.

It’s the life’s work of Mike Wright who since the early 70’s has been recording scientific talks, well before anyone was doing anything like that, resulting in 100.000 hours of recordings. Just to mention a few names in it:

New paper, somewhat different.

I am constantly on the edge, house or not.

Bob Coecke @coecke.bsky.social · Sep 5

Really prefer the name showmen to artist. That's what we do, we make shows.

In back is my old flat in Brussels (lower of the two sticking out on right). I departed in 2001 with Mazda to Oxford, to never come back. 1st Black Tish album was recorded there.

Cheers! I'll be posting about music here. Btw these days I play and compose with Rakhat-Bi Abdyssagin, entangling my quantum guitar either with grand piano or cathedral organ. Last one was in Berlin (see below), next one in Oxford.

Happy to finally announce this long-overdue paper.

TL;DR: We demonstrated that using our diagrammatic formalism, called Quantum Picturalism, high school students can excel at the University of Oxford's postgrad-level quantum exam.

Gonna try my Quantum Guitar paper then.

Bob Coecke @coecke.bsky.social · Sep 3

Ok, so archive accepts quantum art.

Bob Coecke @coecke.bsky.social · Sep 2

I've got a paper on Quantum Guitar that I could send to you.

Bob Coecke @coecke.bsky.social · Sep 2

Indeed, that would allow for other encodings besides midi from a midi-pickup.
