RT Journal Article T1 Generation and Detection of Continuous Variable Quantum Vortex States via Compact Photonic Devices A1 Barral Raña, David A1 Balado Souto, Daniel A1 Liñares Beiras, Jesús K1 Quantum information processing K1 Continuous variables K1 Integrated optics AB A quantum photonic circuit with the ability to produce continuous variable quantumvortex states is proposed. This device produces two single-mode squeezed states which go through a Mach-Zehnder interferometer where photons are subtracted by means of weakly coupled directional couplers towards ancillary waveguides. The detection of a number of photons in these modes heralds the production of a quantum vortex. Likewise, a measurement system of the order and handedness of quantum vortices is introduced and the performance of both devices is analyzed in a realistic scenario by means of theWigner function. These devices open the possibility of using the quantum vortices as carriers of quantum information PB MDPI SN 2304-6732 YR 2017 FD 2017-01-03 LK http://hdl.handle.net/10347/17500 UL http://hdl.handle.net/10347/17500 LA eng NO Barral, D., Balado, D., Liñares, J.
