Oi et al.arXiv preprint·2025·10.1093/nsr/nwaf147/62941607/nwaf147.pdf·arXiv:2501.13902AbstractThe paper demonstrates secure quantum key distribution using a room-temperature single-photon emitter in hexagonal boron nitride (hBN). Multilayer hBN flakes on SiO₂/Si are optically excited and characterized by photoluminescence, lifetime, polarization, and photon-correlation measurements. The emitter shows a zero-phonon line at 626 nm, a lifetime of 4.58 ns, antibunching g2(0)=0.24, and 70% polarization visibility. Using spectrally filtered emission in a 92 protocol implementation at 40 MHz, the experiment achieves a sifted key rate of 17.5 kbps, a quantum bit error rate of 6.49%, and a finite-key secure key rate of 7 kbps.Read more
