压电纳米腔中的自旋-声子-光子强耦合
Spin-Phonon-Photon Strong Coupling in a Piezomechanical Nanocavity
摘要：
我们引入了一个半导体自旋、机械声子和微波光子之间强耦合的混合三重量子系统。该系统由具有集成金刚石应变集中器的压电谐振器组成，实现了微波-声学和自旋-声学耦合速率$\sim$ MHz或更高，允许同时超高协同性（分别为$\sim 10^3$和$\sim 10^2$）。从有限元建模和主方程模拟，我们估计光子自旋量子态转移的结晶度超过0.97的基础上，分别证明了设备参数。我们预计，该设备将实现混合量子架构，利用超导电路和固态自旋的优势进行信息处理，存储和网络。
英文摘要：
We introduce a hybrid tripartite quantum system for strong coupling between a semiconductor spin, a mechanical phonon, and a microwave photon. Consisting of a piezoelectric resonator with an integrated diamond strain concentrator, this system achieves microwave-acoustic and spin-acoustic coupling rates $\sim$MHz or greater, allowing for simultaneous ultra-high cooperativities ($\sim 10^3$ and $\sim 10^2$, respectively). From finite-element modeling and master equation simulations, we estimate photon-to-spin quantum state transfer fidelities exceeding 0.97 based on separately demonstrated device parameters. We anticipate that this device will enable hybrid quantum architectures that leverage the advantages of both superconducting circuits and solid-state spins for information processing, memory, and networking.
