Mini-ions at it again, this time, catching the wave (function).

Highly recommended!
Was fun to record a podcast for @intelligence2.bsky.social with the wonderful host Shini Somara on our book "Why nobody understands quantum physics": scientists and writers, unite! open.spotify.com/episode/6sBG...

So What Do We Know QC To Be Good For?
- Simulating quantum physics and chemistry
- Breaking current public-key encryption (RSA, DH, ECC)
- Eventually, modest (square-root) speedups from Grover
- We’ll have to get lucky for most other applications!
(The world has been systemically lied to about this)

Le Palais de la Découverte est clairement menacé. Voici une petite vidéo où j'essaye de vous expliquer pourquoi, à mon avis, ce serait une vraie erreur de ne pas le réouvrir.

The Palais de la Découverte is facing possible eviction from its historical location in the center of Paris. Consider signing the petition in support of this beloved institution devoted to sharing science with the general public www.change.org/p/sauvons-le...

To demystify the notion that quantum computing owes its advantage to "massive parallelism" I find it useful to compare it to a random walk in a maze. A marble can explore many paths in the maze...

Last week @pintofscience.fr, the werewolves attacked some of our quantum channels but thankfully Alice and Bob were able to detect the intrusion.

Pint of Science is the highlight of my year when it comes to science outreach activities. Thanks to all the organizers for making it happen.
#pint25 that's a wrap! 🔚
🤩 Encore une édition du festival @pintofscience.fr réussie !
Pendant 3 soirs, nous avons appris, rigolé, réfléchi, interagi... c'était top🌟
🙌 Merci à mon équipe, aux intervenant.e.s, aux Fac Sciences et SH de l'@upcite.bsky.social, et à nos sponsors :)

The villagers are asleep. Alice and Bob are trying to establish a secret key but the Werewolves are on the prowl.

Cryptographie quantique, dans l'ombre des Qubits

We have to let go of the Bloch Sphere when adressing the general public. Yes, it is a mathematically correct representation of a single qubit but what intuition do we expect people to get from it?
I think the only thing is conveys is "it's complicated". And we've got to do better than that.

I strongly believe that mathematical notation, not mathematics, is the biggest obstacle when communicating about quantum computing. Two eye-opening reads.
