Happy World Quantum Day to those who do and do not celebrate.

@ionica Already several meetings about Quantum done today.

But, About Post-Quantum Crypotograhy.

This was my favorite.

@harld one of our PhD students gave a talk about the quantum Levine hat problem, which was lovely.

@ionica I'm afraid that by posting this, you have made us aware of World Quantum Day and we are now forced to choose between celebrating or not. You're collapsing so many quantum waves with this post!

@ionica How does one 'observe' World Quantum Day?

[harld@masto.ai]

@ionica Ik zit meer in de hoek van cryptografie en dan is de stap naar Quantum best klein.

En dan bij Radboud University.

@ionica I''ll check my cat to see if I'm celebrating or not.

@ionica wasn't aware. Now I am. Thanks!

@ionica Can I do both at once?

[cymplecy@fosstodon.org]

@ionica And to the ones that don't know if they celebrate it or not at this present moment

@lnkvt @ionica Through a double slit board?

@ionica

I started a standing wave of applause…
but it decohered instantly.

@lnkvt @ionica you can observe quantum day but then you don’t know when it happens.

The smallest holiday

[reinoudk@mastodon.nl]

@ionica

Schrödinger got me on a string today.

[rdp@hachyderm.io]

@ionica At last, a holiday specifically designed to make cats nervous.

[chrisp@cyberplace.social]

@ionica Actually no one knows which day is Quantum Day until we observe it.

[darkwolf@hear-me.social]

@lnkvt @ionica oh boy

[chrisp@cyberplace.social]

@lynfox @ionica Yes. But also, when we observe today as Quantum Day does that mean the previous days were not Quantum Day?

[jd@ottawa.place]

@ionica
I see / didn’t see what you did there.

[tanfonto@hachyderm.io]

@ionica not sure
