On-demand room-temperature single photon array—a quantum communication breakthrough

Phys.org  September 21, 2018 An international team of researchers (USA – City College of New York, Australia, Lithuania) has demonstrated large arrays of room-temperature quantum emitters in two-dimensional hexagonal boron nitride. The large energy gap inherent in substrate-induced deformation in hBN stabilizes the emitters at room temperature within nanoscale regions. Combining analytical and numerical modeling, they showed that emitter activation is the result of carrier trapping in deformation potential wells. The breakthrough has solved a long-standing and practical hurdle of realizing deterministic single photon emitters at room temperature… read more. Open Access TECHNICAL ARTICLE
