• Abstract: A robust quantum light source operating upon electrical injection at ambient conditions is desirable for practical implementation of quantum technologies, such as quantum key distribution or metrology. Color centers in diamond are promising candidates as they are photostable emitters at room and elevated temperatures. The possibility of their electrical excitation has already been demonstrated within p-i-n diodes. However, this requires the growth of complex diamond structures. In contrast to these conventional approaches, we demonstrate the emission of color centers under electrical pumping in a novel Schottky diode configuration based on hydrogen passivated n-type diamond, which holds promise for integrated single-photon emitting devices based on color centers in diamond.

  We introduce a concept that generates a finely tunable PhC cavity at a select wavelength between two heterogeneous optical materials. The cavity is formed by stamping a hard-to-process material with simple waveguide geometries on top of an easy-to-process material. We simulate our concept for the particularly challenging design problem of multiplexed quantum repeaters based on arrays of cavity-coupled diamond color centers.

  Most demanding application for a large-scale quantum computer will require ordered arrays. By configuring an electronic-grade diamond substrate with a biased surface graphene electrode connected to charge-sensitive electronics, it is possible to demonstrate single ion implantation for ions stopping between 30 and 130nm deep from a typical ion source. This allows the construction of ordered arrays of single atoms with associated colour centres that paves the way for the fabrication of deterministic colour center networks in a monolithic device.
