Title: Purcell enhancement of single-photon emitters in silicon
Authors: Andreas Gritsch, Alexander Ulanowski, Andreas Reiserer
Abstract summary: Individual spins that are coupled to telecommunication photons offer unique promise for distributed quantum information processing. We implement such an interface by integrating erbium dopants into a nanophotonic silicon resonator. We observe optical Rabi oscillations and single-photon emission with a 78-fold Purcell enhancement.

Abstract: Individual spins that are coupled to telecommunication photons offer unique promise for distributed quantum information processing once a coherent and efficient spin-photon interface can be fabricated at scale. We implement such an interface by integrating erbium dopants into a nanophotonic silicon resonator. We achieve spin-resolved excitation of individual emitters with < 0.1 GHz spectral diffusion linewidth. Upon resonant driving, we observe optical Rabi oscillations and single-photon emission with a 78-fold Purcell enhancement. Our results establish a promising new platform for quantum networks.

On-chip quantum information processing with distinguishable photons [55.41644538483948]
Multi-photon interference is at the heart of photonic quantum technologies. Here, we experimentally demonstrate that detection can be implemented with a temporal resolution sufficient to interfere photons detuned on the scales necessary for cavity-based integrated photon sources. We show how time-resolved detection of non-ideal photons can be used to improve the fidelity of an entangling operation and to mitigate the reduction of computational complexity in boson sampling experiments.

Resonant Excitation and Purcell Enhancement of Coherent Nitrogen-Vacancy Centers Coupled to a Fabry-P\'{e}rot Micro-Cavity [0.0]
nitrogen-vacancy (NV) center in diamond has been established as a prime building block for quantum networks. Poor optical coherence of near-surface NV centers has so far prevented their resonant optical control, as would be required for entanglement generation. We demonstrate resonant addressing of individual, fiber-cavity-coupled NV centers, and collection of their Purcell-enhanced coherent photon emission.
