In classical digital logic, we have K-map and Quine–McCluskey algorithm to minimize boolean equation, thereby reducing the number of logic gates needed. Is there such a thing in quantum computing?.
One of the exercises from IBM Quantum Summer School 2022 is to achieve this quantum state
and this is my solution (which passed grader check)
The question is: in general, how do I know that a derived circuit is optimal/state of the art?
