Narrowband heralded single photons via Bragg grating inscription in germanium-doped photonic crystal fiber
Will A. M. Smith, Alex I. Flint, Rex H. S. Bannerman +4
We present a fiber-based source of narrowband heralded single photons in the telecoms C-band. Photon pairs were generated by spontaneous four-wave mixing in photonic crystal fiber…
Phase-sensitive characterization of a quantum frequency converter by spectral interferometry
Mateusz J Olszewski, Kasper Hecht Alexander, Michael T M Woodley +3
We introduce an experimental technique for complete phase-sensitive characterization of arbitrary unitary spectral-temporal transformations of optical modes. Our method recovers th…
Quantum Theory of Distributed-Feedback Parametric Amplifiers and Oscillators
Alex O. C. Davis, Alex I. Flint
Optical parametric oscillators are among the best-developed quantum light sources, having already been adopted in precision measurement and underpinning various quantum computing a…
Cavity-based optical switching via phase modulation in warm rubidium vapor
Georgia Booton, Tabijah Wasawo, William O. C. Davis +5
Optical switching remains a key outstanding challenge for scalable fault-tolerant photonic quantum computing due to the trade-off between speed, bandwidth, and loss. Scalable quant…
Microstructured optical fibres for quantum applications: perspective
Cameron McGarry, Kerrianne Harrington, Alex O. C. Davis +2
Recent progress in the development and applications of microstructured optical fibres for quantum technologies is summarised. The optical nonlinearity of solid-core and gas-filled…
