Qi Guo, which consists of a multimode high-frequency bulk acoustic wave resonator and a transmon-type superconducting qubit. Two acoustic modes couple to the qubit through piezoelectric interaction, so the entanglement between acoustic modes can be created by the direct unitary evolution. We numerically analyze the parameter conditions for generating the entanglement in detail and evaluate the influence of system dissipations and noise. The results show that the scheme can be realized using currently available parameters and has strong robustness against the dissipations and the environmental temperature. This work may provide an efficient resource for the quantum information processing based on the phononic systems.

因此声学模式之间的纠缠可以通过直接幺正演化产生, thus establishing the indirect interaction between the two acoustic modes. We demonstrate that such an indirect interaction can be a parametric-amplification-type interaction by appropriately choosing the drive frequency and strength,山西大学张天才团队实现了在电路量子声动力学系统中通过驱动量子比特产生两种声模的纠缠,并且对耗散和环境温度具有很强的鲁棒性,两个声模通过压电相互作用耦合到量子比特, 附:英文原文 Title: Generating entanglement of two acoustic modes by driving the qubit in a circuit quantum acoustodynamics system Author: Mei-Rong Wei,最新IF:2.97 官方网址: https://journals.aps.org/pra/ 投稿链接: https://authors.aps.org/Submissions/login/new ,在量子比特与声模之间存在远失谐的条件下,从而建立两种声模之间的间接相互作用。
量子比特由微波场驱动。
这种间接相互作用可以是参数放大型相互作用,量子比特可以绝热消除,隶属于美国物理学会, the qubit can be eliminated adiabatically, and the qubit is driven by a microwave field. Under the condition of far detuning between the qubit and acoustic modes,通过适当选择驱动频率和强度, Tiancai Zhang IssueVolume: 2025/05/08 Abstract: We propose how to generate the entanglement of two long-lived phonon modes in a circuit quantum acoustodynamics system, 研究组提出了如何在由多模高频体声波谐振器和transmon型超导量子比特组成的电路量子声动力学系统中产生两个长寿命声子模的纠缠,通过详细数值分析了产生纠缠的参数条件,。
