Quantum leaps are discrete beacuse they behave like stationary waves.
Here we have 3 qubits on a single saxophone!

His book "Mathematica" is a real eye-opener. David Bessis describes accurately and vividly the way we perceive and manipulate mathematical objects. Colleagues who read it also felt he put into words what they had not been able to formulate about the mathematical process. Highly recommended.
The mathematician David Bessis believes that mathematical skill is not innate, but learned. “Genius is not an essence. It’s a state. It’s a state that you build by doing a certain job.”
Mathematical Thinking Isn’t What You Think It Is | Quanta Magazine
The mathematician David Bessis claims that everyone is capable of, and can benefit greatly from, mathematical thinking.

Who knew? A quote from David Sulzer’s Math Music and Mind on how harmonics in music inspired de Broglie’s view of quanta.

It's easier to understand quantum algorithms if you think of qubits as waves with an amplitude and a phase. Come play with our music installation u-paris.fr/sciences/%C3...

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

The mini-ions are back.

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.

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 werewolves are on the prowl but the villagers are prepared!
Next week at @pintofscience.fr, werewolves will attack BB84 quantum channels #pint25

The villagers are asleep. Alice and Bob are trying to establish a secret key but the Werewolves are on the prowl.
Register on April 14th for Pint of Science to join a game of quantum werewolves.
