Optimised Domain-engineered Crystals for Pure Telecom Photon Sources
Alexander Pickston, Francesco Graffitti, Peter Barrow +4
The ideal photon-pair source for building up multi-qubit states needs to produce indistinguishable photons with high efficiency. Indistinguishability is crucial for minimising erro…
Hyperentanglement in structured quantum light
Francesco Graffitti, Vincenzo D'Ambrosio, Massimiliano Proietti +5
Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protoc…
A quantum Fredkin gate
Raj B. Patel, Joseph Ho, Franck Ferreyrol +2
Key to realising quantum computers is minimising the resources required to build logic gates into useful processing circuits. While the salient features of a quantum computer have…
Efficient and pure femtosecond-pulse-length source of polarization-entangled photons
Morgan M. Weston, Helen M. Chrzanowski, Sabine Wollmann +9
We present a source of polarization entangled photon pairs based on spontaneous parametric downconversion engineered for frequency uncorrelated telecom photon generation. Our sourc…
