Maud Vinet, la grande ordinatrice quantique

L’ordinateur quantique ne cesse d’attirer les convoitises. Comment nos connaissances en microélectronique peuvent-elles accélérer le développement de ces machines ? Après des années à travailler sur le sujet, Maud Vinet a co-fondé Quobly et souhaite commercialiser un ordinateur quantique.

Big update on my quantum playground: It now supports entangled qbits !

I've implemented the CNOT gate and build a circuit with 2 qbits. When you modify the 1st qbit, you can see the 2nd one being impacted by the 1st one.

I gave up putting an “Add Gate” button, because “Add” also imply a “Remove” button, and when I tried to remove a gate, my quantum circuit crash. I'm afraid this may create a breach in the continuum of reality that would collapse our entire universe. So I estimate it is safer for now to not remove a gate from an existing circuit.

Anyway, enjoy here: https://kissyagni.com/the-quantum-playground

As I slowly understand how Quantum Computing works, I decided to extand my Bloch Sphere viewer to a more ambitious Quantum Playground.

It now have section to play with a QBit or with a circuit containing 1 QBit and a 1 QGate. Several gates in a row should come soon, as it already works. But I need to add a "Add Gate" button and CSS hates me 🥺

Circuit with several QBits in a separable state seems to work, but I still didn't test entangled state. I have to implement a CNOT gate first. Cross fingers 🤞.

I've spent way too much time implementing reflexion and refraction on my #BlochSphere viewer.

I should work on multi #qbits support instead, but.. you know... #raytracing is cool 😎

I continue my #raytraced #blochsphere in #threejs .

Add poor man's phong shading and per primitive color. Also add some labels for main #qbits axes.

I've looked at the numbers in Google paper. #BTC uses elliptical curve, which is easier to break than RSA.
Based on the growth in #qbits necessary, the critical vulnerability window will begin in 2030.
This sounds far away, but it's only 5 years.

By then they will have to recode the BTC Blockchain to quantum-resistant cryptography (your post has a link to a paper).
However, I would totally expect a nation state to hit that benchmark sooner and raid the BTC.
