We have detected a spin-dependent displacement perpendicular to the refractive index gradient for photons passing through an air-glass interface. The effect is the photonic version of the spin Hallâ€¦ (More)

Quantum metrology uses quantum entanglementâ€”correlations in the properties of microscopic systemsâ€”to improve the statistical precision of physical measurements. When measuring a signal, such as theâ€¦ (More)

We demonstrate a Raman laser using cold (87)Rb atoms as the gain medium in a high-finesse optical cavity. We observe robust continuous wave lasing in the atypical regime where single atoms canâ€¦ (More)

The logic underlying the coherent nature of quantum information processing often deviates from intuitive reasoning, leading to surprising effects. Counterfactual computation constitutes a strikingâ€¦ (More)

Quantum metrology exploits entangled states of particles to improve sensing precision beyond the limit achievable with uncorrelated particles. All previous methods required detection noise levelsâ€¦ (More)

We present two methods for the precise independent focusing of orthogonal linear polarizations of light at arbitrary relative locations. Our first scheme uses a displaced lens in a polarizationâ€¦ (More)

We present the first demonstration of Jozsa's "counterfactual computation", using an optical Grover's search algorithm. We put the algorithm in a superposition of "running" and "not-running",â€¦ (More)

We study the free expansion of a pancake-shaped Bose-condensed gas, which is initially trapped under harmonic confinement and containing a vortex at its centre. In the case of a radial expansionâ€¦ (More)

A source of single photons allows secure quantum key distribution, in addition, to being a critical resource for linear optics quantum computing. We describe our progress on deterministicallyâ€¦ (More)
