Big refact on my #BlochSphere viewer project. I've ported the js code to #angular and moved it into its own repo: https://codeberg.org/KissYagni/quantum-playground.

I plan to not only show a single QBit, but build more complex circuit. And to do so, I will need more advanced Ux than 2 slider stuck on the left.

Quantum Processing – The Controled Gates.

We have seen before some quantum gates acting on a single qbit. We will now see a family of qgates taking 2 qbits as input and returning 2 qbits: the Controlled gates. – Why does it return 2 qbits ? In classical logic, gates take 2 bits and return only 1 bit …

Curious, I looked up "post-quantum cryptography":

Quantum computers, with, for example Shor's algorithm, can factor primes. Wikipedia says:

- In 2001 [...] factored 15 into 3 × 5
- In 2012, the factorization of 15 was performed [...]
- in 2012, the factorization of 21 was achieved.
- In 2016, the factorization of 15 was performed

Hmm, not exactly a Moore's law yet.🤔 128 bit primes are a long way to go.

My #Blochsphere slowly start to be something. I can now represent #Quantum gate effect on a #Qbit.

PauliZ is easy to understand, PauliX and PauliY , Mmm..... Ok, but Hadamard gate is more tricky.

Why I Left Quantum Computing Research

@darkuncle I like that phrase, "attacks always get better, they never get worse"

Can I propose an alternative? Do not look for quantum-resistant encryption. Rather replace the entire existing public-key-private key cryptography with something entirely new. If possible something based on quantum computing principles.
