Added the :class:`.UnitaryOverlap` circuit to the Qiskit circuit library that
|
|
can be used to compute the fidelity of states generated by unitaries
|
|
by looking at the probability of the output distribution in the all-zeros
|
|
state or, equivalently, by computing the expectation value of the projector
|
|
onto the all-zeros state. This is useful in applications such as machine
|
|
learning, and computing excited states in quantum chemistry, to name a few.
