Abstract
There are provided optical quantum logic gate (OQLG) characterized by 2*2unitary matrix and method of operating thereof. OQLG comprises first optical structure comprising 2optically-coupled cores with one-to-one correspondence to input binary values specified by the matrix and second optical structure optically connected to the first optical structure and comprising 2amplifying channels corresponding to the 2cores. The first optical structure is configured to receive photons in binary fundamental quantum states (FQSs) representing input binary values specified by the matrix and to inject the received photons in the 2cores, use optical coupling between the cores to mix the injected photons, and output photons into the second optical structure, wherein outputted mixed photons correspond to output binary values specified by the matrix. The second optical structure is configured to amplify, in a controllable manner, photons in the amplifying channels with preserving the FQSs and relative quantities of photons with different FQSs.
