    "abstract": "A light beam is said to be position squeezed if its position can be\ndetermined to an accuracy beyond the standard quantum limit. We identify the\nposition and momentum observables for bright optical beams and show that\nposition and momentum entanglement can be generated by interfering two\nposition, or momentum, squeezed beams on a beam splitter. The position and\nmomentum measurements of these beams can be performed using a homodyne detector\nwith local oscillator of an appropriate transverse beam profile. We compare\nthis form of spatial entanglement with split detection-based spatial\nentanglement.",
