摘要

研究人员通过光机械系统中的四阶达芬非线性，对基于声子态的通用量子门实现的可能性进行了可行性研究。光机械系统由 N 个双钳位耦合纳米束阵列组成，由局部静态和射频电势驱动，并与单模高精细光腔耦合。结果表明，只有在耗散过程可忽略不计的非共振动力学条件下，才能实现理想的 cnot 栅极。

Implementation of controlled-not quantum gate by nonlinear coupled electro-nano-optomechanical oscillators

A feasibility study is done for the possibility of a universal set of quantum gate implementation based on phononic state via fourth-order Duffing nonlinearity in an optomechanical system. The optomechanical system consists of

N

doubly clamped coupled nanobeam arrays driven by local static and radio frequency electrical potentials, coupled to a single-mode high-finesse optical cavity. The results show that the ideal cnot gate can be implemented only under nonresonance dynamics when the dissipation processes are negligible.
