Efficient Quantum Emulation of Unknown Unitaries
We propose a quantum algorithm, termed the universal quantum emulator, that emulates the action of an unknown unitary transformation or its inverse on a given input state, using multiple copies of some unknown sample input states of the unitary and their corresponding output states. The algorithm do...
