- Abstract: High-purity single photon sources (SPS) that can operate at room temperature
are highly desirable for a myriad of applications, including quantum photonics
and quantum key distribution. In this work, we realise an ultra-bright
solid-state SPS based on an atomic defect in hexagonal boron nitride (hBN)
integrated with a solid immersion lens (SIL). The SIL increases the source
efficiency by a factor of six, and the integrated system is capable of
producing over ten million single photons per second at room temperature. Our
results are promising for practical applications of SPS in quantum
communication protocols.
