First published by Fourier in 1807 to solve the heat equation.

electroweak interaction + strong interaction.

Appears to be an unsolved physics problem. TODO why? Don't they all fit into the Standard Model already? So why is strong force less unified with electroweak, than electromagnetic + weak is unified in electroweak?

Ciro Santilli has a tutorial at Linux Kernel Module Cheat.

At Section "Quantum computing is just matrix multiplication" we saw that making a quantum circuit actually comes down to designing one big unitary matrix.

We have to say though that that was a bit of a lie.

Quantum programmers normally don't just produce those big matrices manually from scratch.

Instead, they use quantum logic gates.

The following are the main reasons for that:

There is just one key gotcha: the project has to be useful.
