How to construct solution based on the Schrödinger equation and split it into gates?

Recall that a time-dependent unitary operator (technically a one-parameter group) $U$ can be generated by a Hermitian operator $H$(the generator) $$ U(t) = \exp(-itH) $$ This in turn gives us the ...

Quantum gates for more than two basis states

If you want the best possible evolution for your qubit space, then you simply don't define what your target is on the rest of the space - so long as you always start in the two-dimensional subspace/...

How to comparing a quantum channel with a unitary?

I found the following two works solving this problem. They selected several reference states and took the HS product between the final states evolved by the target unitary and the quantum channel. ...
