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.
