A proposal for the implementation of quantum gates in an optomechanical system via phonon blockade. (25th September 2019) - Meher, Nilakantha
Abstract: We propose a scheme to implement quantum controlled NOT gate and quantum phase gate in an optomechanical system based on phonon blockade. For appropriate choices of system parameters, the fidelities of both quantum gate operations are very close to unity in the absence of dissipation. Using recently achieved experimental values in a mechanical resonator coupled to a microwave cavity, we show that the quantum gate can be realized experimentally with very high fidelity.
