Toward a Scalable Linear-Cavity Enhanced Warm-Vapor Photonic Quantum Memory
Bharath Srivathsan, Rafal Gartman, Robert J. A. Francis-Jones +2
The coherent storage, buffering and retrieval of photons in a quantum memory enables the scalable creation of photonic entangled states via linear optics and repeat-until-success,…
Resource-efficient frequency conversion for quantum networks via sequential four-wave mixing
Thomas A. Wright, Charlotte Parry, Oliver R. Gibson +2
We report a resource-efficient scheme in which a single pump laser was used to achieve frequency conversion by Bragg-scattering four-wave mixing in a photonic crystal fiber. We dem…
Spectrally pure single photons at telecommunications wavelengths using commercial birefringent optical fiber
Jasleen Lugani, Robert J. A. Francis-Jones, Joelle Boutari +1
We report a bright and tunable source of spectrally pure heralded single photons in the telecom O-Band, based on cross-polarized four wave mixing in a commercial birefringent optic…
Engineered photon-pair generation by four-wave mixing in asymmetric coupled waveguides
Robert. J. A. Francis-Jones, Thomas A. Wright, Andriy V. Gorbach +1
Third-order nonlinear processes require phase matching between the interacting fields to achieve high efficiencies. Typically in guided-wave platforms this is achieved by…
A two-way photonic interface for linking Sr+ transition at 422 nm to the telecommunications C-band
Thomas A. Wright, Robert J. A. Francis-Jones, Corin B. E. Gawith +7
We report a single-stage bi-directional interface capable of linking Sr+ trapped ion qubits in a long-distance quantum network. Our interface converts photons between the Sr+ emiss…
Resource-efficient fibre-integrated temporal multiplexing of heralded single photons
Rowan A. Hoggarth, Robert J. A. Francis-Jones, Peter J. Mosley
We present a multiplexed single photon source that re-synchronises heralded single photons generated by four-wave mixing in photonic crystal fibre using a fibre delay loop controll…
