Quantum Computing

I've created a nice quantum computing cheat sheet. It's not just a patchwork of stuff I've googled. It's a synthesis of everything I've understood in the last few month.

There are things I had to get by myself because no one clearly mentioned it. Like the fact that Wikipedia pages on Quantum Gates use "1st qubit leftmost" convention whereas Qiskit use "1st qubit rightmost".

Anyway, here it is: https://kissyagni.com/TheQuantumComputingCheatSheet.pdf

Use it, Share it, and even Correct it 😊

Any time you use a device to communicate information—an email, a text message, any data transfer—the information in that transmission crosses the open internet, where it could be intercepted. Such communications are also reliant on internet connectivity, often including wireless signal on either or both ends of a transmission.

But what if two—or 10, or 100, or 1,000—entities could be connected in such a way that they could communicate information without any of those security or connectivity concerns?

What do these things even do 😭

I'm currently playing with qiskit, the IBM Python library for quantum computing. I don't know if it is good or bad; I just took the first one I found.

I finally understood the Deutsch Algorithm.

All the articles I found dealt with the equations too quickly, and my math is a little rusty. Also, I never studied tensor spaces in school, so handling tensor products is far from natural.

I detailed every single steps here: https://kissyagni.com/the-deutsch-algorithm.html

There are probably more compact method to explain the algorithm, but this the one that worked for me.

New article about #quantum_computing where I tackle controlled gates:

I'm continuing digging into quantum computing with some Quantum gates acting on a single QBit. Next one will be on multiple Qbit gates.

Representing Bloch sphere with sketches is a bit challenging. I'll try to find a better way to do this.

Just started my journey into quantum computing. I hope this would help beginners to understand what the hell is this thing 😊
