Further Compactifying Linear Optical Unitaries
Bryn A. Bell, Ian A. Walmsley
Quantum integrated photonics requires large-scale linear optical circuitry, and for many applications it is desirable to have a universally programmable circuit, able to implement…

Engineering Schrödinger cat states with a photonic even-parity detector
G. S. Thekkadath, B. A. Bell, I. A. Walmsley +1
When two equal photon-number states are combined on a balanced beam splitter, both output ports of the beam splitter contain only even numbers of photons. Consider the time-reversa…

Shape-preserving and unidirectional frequency conversion using four-wave mixing Bragg scattering
Jesper B. Christensen, Jacob G. Koefoed, Bryn A. Bell +2
In this work, we investigate the properties of four-wave mixing Bragg scattering in a configuration that employs orthogonally polarized pumps in a birefringent waveguide. This conf…
