摘　　要：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.
