A single optically detectable tumbling spin in silicon

Félix Cache, Yoann Baron, Baptiste Lefaucher +9

We demonstrate single spin spectroscopy of a fluorescent tumbling defect in silicon called the G center, behaving as a pseudo-molecule randomly reorienting itself in the crystallin…

Bright and pure single-photon source in a silicon chip by nanoscale positioning of a color center in a microcavity

Baptiste Lefaucher, Yoann Baron, Jean-Baptiste Jager +8

We present an all-silicon source of near-infrared linearly-polarized single photons, fabricated by nanoscale positioning of a color center in a silicon-on-insulator microcavity. Th…

Purcell enhancement of silicon W centers in circular Bragg grating cavities

Baptiste Lefaucher, Jean-Baptiste Jager, Vincent Calvo +11

Generating single photons on demand in silicon is a challenge to the scalability of silicon-on-insulator integrated quantum photonic chips. While several defects acting as artifici…

Parallelizable Synthesis of Arbitrary Single-Qubit Gates with Linear Optics and Time-Frequency Encoding

Antoine Henry, Ravi Raghunathan, Guillaume Ricard +5

We propose novel methods for the exact synthesis of single-qubit unitaries with high success probability and gate fidelity, considering both time-bin and frequency-bin encodings. T…

Cavity-enhanced zero-phonon emission from an ensemble of G centers in a silicon-on-insulator microring

B. Lefaucher, J. -B. Jager, V. Calvo +13

We report successful incorporation of an ensemble of G centers in silicon-on-insulator (SOI) microrings using ion implantation and conventional nanofabrication. The coupling betwee…
