We are working on a cut-out book with interactive gates and measurement devices to teach quantum computing. Would you be interested in using something like this, and if so, what age group would you use this for?

What happens if you have two opposite waves in superposition? See next post... An excerpt from Peter (Shor) and the Wolf, performed at @pintofscience.fr Music by Fabrice Villard. Photo credit Lucie Peinturier.

Quantum leaps are discrete beacuse they behave like stationary waves. Here we have 3 qubits on a single saxophone! (Pierre-Stéphane Meugé at Studio Sequenza)

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.

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...

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!

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...

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.

Two qubits side by side, are correlated by a cog to illustrate entanglement. If we stack the qubits, we can see that 2 qubits form a 4-dimensional system. It becomes easy to visualize partial traces and partial measurements.

QuBobs @qubobs.bsky.social · 20/11/2024
A device to help visualize quantum entanglement. Each qubit is a 2-colored disc. We measure them by spinning around and stopping at a random spot. Whatever is visible in the measurement window is the outcome. We can see the correlation between the meausurement outcomes when the cog is in place.
