摘要:

捕获离子系统中的振动自由度最近作为量子资源而受到关注,超越了作为在内部自由度上纠缠量子操作的介体的作用,这是因为大的可用希尔伯特空间。振动模式可以表示为量子谐振子,从而提供了一个无限维的希尔伯特空间。在这里,我们回顾了最近的理论和实验进展的相干操纵的振动模式,包括玻色子编码方案在量子信息,可靠和有效的测量技术,和量子操作,使各种量子模拟和量子计算算法。我们描述了使用振动模式的实验,包括非经典态的制备,分子振动采样,以及在量子热力学中的应用。最后讨论了离子捕获振动模量子信息处理的潜在前景和挑战。

英文摘要:

Vibrational degrees of freedom in trapped-ion systems have recently been gaining attention as a quantum resource, beyond the role as a mediator for entangling quantum operations on internal degrees of freedom, because of the large available Hilbert space. The vibrational modes can be represented as quantum harmonic oscillators and thus offer a Hilbert space with infinite dimension. Here we review recent theoretical and experimental progress in the coherent manipulation of the vibrational modes, including bosonic encoding schemes in quantum information, reliable and efficient measurement techniques, and quantum operations that allow various quantum simulations and quantum computation algorithms. We describe experiments using the vibrational modes, including the preparation of non-classical states, molecular vibronic sampling, and applications in quantum thermodynamics. We finally discuss the potential prospects and challenges of trapped-ion vibrational-mode quantum information processing.
