Experimental Demonstration of Non-local Controlled-Unitary Quantum Gates Using a Five-qubit Quantum Computer. (arXiv:1709.05697v3 [quant-ph] UPDATED)

Local implementation of non-local quantum gates is necessary in a distributed
quantum computer. Here, we demonstrate the non-local implementation of
controlled-unitary quantum gates proposed by Eisert et al. (Phys Rev A
62:052317, 2000) using the five-qubit IBM quantum computer. We verify the
fidelity and accuracy of the implementation through the techniques of quantum
state and process tomographies.
