摘要

开发一种明亮的、确定性的纠缠光子对源一直是一项杰出的科学和技术挑战。半导体量子点是这一任务的理想候选者。一种结合了环形布拉格共振器和压电致动器的新装置同时实现了高亮度和纠缠保真度，克服了以往的限制。这一突破增强了量子点在基于纠缠的量子通信协议中的应用。

Quantum dots get a bright upgrade

Developing a bright, deterministic source of entangled photon pairs has been an outstanding scientific and technological challenge. Semiconductor quantum dots are a promising candidate for this task. A new device combining a circular Bragg resonator and a piezoelectric actuator achieves high brightness and entanglement fidelity simultaneously, overcoming previous limitations. This breakthrough enhances quantum dot applications in entanglement-based quantum communication protocols.
