六方氮化硼中声子耦合的室温单光子发射

Phonon-coupled single photon emitters in hexagonal boron nitride at room-temperature

光子是飞行的量子比特,将单光子与其他量子体系耦合是实现光子计数操控量子态的前提.最近的研究报道了六方氮化硼(hBN)中声子耦合的单光子发射,通过电子跃迁模型解释了声子参与的缺陷态激发和单光子发射过程,这一结果为室温单量子水平下操控电子-声子耦合提供了可能.

Photons can work as flying qubits.Coupling single photons with other systems is crucial for quantum manipulation and quantum information transduction.A recent study by Lai et al.reported the phonon-coupled single photon emission in hexagonal boron nitride.A transition model was developed to explain the phonon-assisted defect emission.This result provides insight into manipulating electron-phonon coupling with single photon at room temperature.
