Start with a qubit in state |0>, apply X, then measure.

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

QuBobs @qubobs.bsky.social · Aug 18

The mini-ions are back.

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)

Make that a polylog factor and I'm in.

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...

Go with the vibe function.

In any execution, there is only a small probability that your marble has reached the exit of the maze. The same goes for quantum algorithms. Parallel executions don't help unless you can amplify the probability of getting a correct answer in the end. This is where much of the power of quantum lies.

QuBobs @qubobs.bsky.social · May 27

If you want to describe the location of a marble in a maze at a given time, you could describe it as being in all possible locations, with some probability. This sounds a lot like "massive parallelism", but there's nothing strange or quantum about it.

QuBobs @qubobs.bsky.social · May 27

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.

Cards for the BB84 werewolves game on the bar.

Eve/werewolf poised for an attack on a quantum channel.

Revealing the qubits sent, intercepted, and measured to detect intrusion.

Aha! The plot thickens.

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

It was supposed to arrive last Friday but I haven't heard back yet. I'll ask them again.

We can make a pop-up book!
Anyone know of an editor who would be interested?

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.
