论文摘要
光子阻滞效应通常在单光子源的发展中被利用。尽管光子阻滞效应可用于在理想化的方案中准备高保真单光子状态,但在光力学系统中的实际实现却遭受了竞争过程的相互作用。在这里,我们得出了一种控制方案,该方案利用了多个光子的Fock状态幅度的破坏性干扰。光子阻滞量子状态的制备时间仅受光力相互作用强度的限制,因此比在稳态下实现光子阻滞状态的现有方案的数量级可以短。
The photon blockade effect is commonly exploited in the development of single-photon sources. While the photon blockade effect could be used to prepare high-fidelity single-photon states in idealized regimes, practical implementations in optomechanical systems suffer from an interplay of competing processes. Here we derive a control scheme that exploits destructive interference of Fock state amplitudes of more than one photon. The resulting preparation time for photon-blockaded quantum states is limited only by the optomechanical interaction strength and can thus be orders of magnitude shorter than in existing schemes that achieve photon-blockaded state in the steady state.
