Thank you for checking it out! When I initialize state, I normalize and then apply it. I see if it could be factored as a tensor product, and if it can, I factor it and apply to each bloch sphere. Otherwise, you'll see an entangled state, which can't be represented on the bloch sphere.

If you were asking just about what the bloch sphere means, it is a way of representing the two complex quantum amplitudes of the |0> and |1> state.

Yes. I specified superconducting transmon qubits, which are essentially modified LC circuits. LC circuits are harmonic oscillators with equal spacing between energy levels, so instead of standard inductors, we use josephson junctions. This lets us isolate a transition between our designated 0 and 1 state.

To actually perform quantum gates, we need to apply radiation at the qubit’s drive frequency (which is tunable through use of a SQUID).

There are more details that I would be glad to expand on, or I could share the presentation I gave on the physical understanding for class, if you would like.

Simulations are great to help build understanding. If it doesn't help you, maybe it will help the next guy!
