Quantum Enhanced Multiple Phase Estimation
Peter C. Humphreys, Marco Barbieri, Animesh Datta +1
We study the simultaneous estimation of multiple phases as a discretised model for the imaging of a phase object. We identify quantum probe states that provide an enhancement compa…
High quantum-efficiency photon-number-resolving detector for photonic on-chip information processing
Brice Calkins, Paolo L. Mennea, Adriana E. Lita +11
The integrated optical circuit is a promising architecture for the realization of complex quantum optical states and information networks. One element that is required for many of…
Linear Optical Quantum Computing in a Single Spatial Mode
Peter C. Humphreys, Benjamin J. Metcalf, Justin B. Spring +5
We present a scheme for linear optical quantum computing using time-bin encoded qubits in a single spatial mode. We show methods for single-qubit operations and heralded controlled…
On-chip low loss heralded source of pure single photons
Justin B. Spring, Patrick S. Salter, Benjamin J. Metcalf +9
A key obstacle to the experimental realization of many photonic quantum-enhanced technologies is the lack of low-loss sources of single photons in pure quantum states. We demonstra…
