We propose a versatile dynamic optical-field manipulator using a coherently prepared atomic medium. We show that by locking the pump power change with the two-photon detuning, a π-phase shifting can be realized with unit probe fidelity in a broad two-photon detuning range. The two-photon-insensitive π-phase-shift mode with significantly reduced fluctuation makes this scheme an attractive system for low-noise phase-gate operations.
我们提出了一种使用相干制备原子介质的多功能动态光场操纵器。我们表明,通过将泵浦功率变化与双光子失谐锁定,可以在很宽的双光子失谐范围内以单位探测保真度实现π相移。具有显著降低波动的双光子不敏感π相移模式使该方案成为用于低噪声相位门操作的有吸引力的系统。
