论文摘要

基于动力学的量子性认证是一种方法,可以在假设其动力学已知的假设下见证某些连续变化状态的非经典特征。与单个系统的非经典性测试相反,它不需要顺序测量。引入了用于谐波动态的协议系列。在这项工作中,我们讨论了基于动力学的一定程度自由的认证,该认证是在一般与时间独立的哈密顿式化合物下演变的。我们表征了这种认证的可能条件。明确研究了几个示例,其中一些示例在低能(Kerr非线性,摆和摩尔斯电位)的极限上大致谐波,而一个不是(无限井中的粒子)。

Dynamics-based certification of quantumness is an approach to witnessing the nonclassical character of some continuous-variable states, under the assumption that their dynamics is known. Contrary to other tests of nonclassicality for single systems, it does not require sequential measurements. This family of protocols was introduced for harmonic dynamics. In this work we discuss dynamics-based certification for one degree of freedom evolving under a generic time-independent Hamiltonian. We characterize the conditions under which such a certification is possible. Several examples are explicitly studied, some that are approximately harmonic in the limits of low energy (Kerr nonlinearities, the pendulum, and the Morse potential) and one that is not (the particle in an infinite well).
