Continuous-variable spatial entanglement for bright optical beams

Hsu, Magnus; Bowen, Warwick P; Lam, Ping Koy; Treps, Nicolas


A light beam is said to be position squeezed if its position can be determined to an accuracy beyond the standard quantum limit. We identify the position and momentum observables for bright optical beams and show that position and momentum entanglement can be generated by interfering two position, or momentum, squeezed beams on a beam splitter. The position and momentum measurements of these beams can be performed using a homodyne detector with local oscillator of an appropriate transverse beam...[Show more]
