通过油藏工程实现非互易光子传输和放大

Nonreciprocal Photon Transmission and Amplification via Reservoir Engineering

A. Metelmann, A. A. Clerk

摘要:

我们讨论了一个一般的方法来构建非互易,基于腔的光子器件,匹配一个给定的相干相互作用与相应的耗散对应物的基础上,我们的方法概括了级联量子系统理论中使用的基本结构,并可以呈现一个非常广泛的类的相互作用方向。与标准的基于干扰的方案相比,我们的方法允许在宽带宽上的定向行为。我们展示了如何可以用来设计隔离器和定向,量子限制放大器。我们将详细讨论如何使用这种一般方法来构造一个定向的、无噪声的相敏放大器,它不受任何基本增益带宽约束的限制。我们的方法特别适合于使用超导微波电路和光机系统的实现。

英文摘要:

We discuss a general method for constructing nonreciprocal, cavity-based photonic devices, based on matching a given coherent interaction with its corresponding dissipative counterpart; our method generalizes the basic structure used in the theory of cascaded quantum systems, and can render an extremely wide class of interactions directional. In contrast to standard interference-based schemes, our approach allows directional behavior over a wide bandwidth. We show how it can be used to devise isolators and directional, quantum-limited amplifiers. We discuss in detail how this general method allows the construction of a directional, noise-free phase-sensitive amplifier that is not limited by any fundamental gain-bandwidth constraint. Our approach is particularly well-suited to implementations using superconducting microwave circuits and optomechanical systems.
