摘要

我们的理论和数值研究探讨了由一个纳米力学和两个量子比特模式组成的纳米力学谐振器-量子比特系统的声子统计，其中力学类型与量子比特模式和力学模式都耦合，并表现出克尔非线性。我们解析地理解了由不同跃迁路径间的破坏性干涉所造成的异常声子阻滞的最佳条件。我们的数值评估值二阶声子相关函数，并研究其对不同系统参数的依赖性。结果表明，解析得到的最优条件与数值结果一致。

Unconventional Phonon Blockade in a Nanomechanical Resonator Coupled to Double Qubit System

Our theoretical and numerical study explores the phonon statistics of a nanomechanical resonator-qubit system which consists of one nanomechanical and two qubit modes in which the mechanical genre is coupled with both the qubit modes and the mechanical mode exhibits Kerr nonlinearity. We analytically apprehend the optimal conditions of anomalistic phonon blockade created by destructive interference between different transition pathways. Our numerically assessment values the second-order phonon correlation function and studies its dependence on different system parameters. It is observed that the analytically obtained optimal conditions are supported by the numerical results.

期刊介绍： The Brazilian Journal of Physics is a peer-reviewed international journal published by the Brazilian Physical Society (SBF). The journal publishes new and original research results from all areas of physics, obtained in Brazil and from anywhere else in the world. Contents include theoretical, practical and experimental papers as well as high-quality review papers. Submissions should follow the generally accepted structure for journal articles with basic elements: title, abstract, introduction, results, conclusions, and references.
