Faculty Applied Sciences Department QN/Quantum Nanoscience Date 2011-11-15 Abstract We characterize a periodically poled KTP crystal that produces an entangled, two-mode, squeezed state with orthogonal polarizations, nearly identical, factorizable frequency modes, and few photons in unwanted frequency modes. We focus the pump beam to create a nearly circular joint spectral probability distribution between the two modes. After disentangling the two modes, we observe Hong-Ou-Mandel interference with a raw (background corrected) visibility of 86% (95%) when an 8.6 nm bandwidth spectral filter is applied. We measure second order photon correlations of the entangled and disentangled squeezed states with both superconducting nanowire single-photon detectors and photon-number-resolving transition-edge sensors. Both methods agree and verify that the detected modes contain the desired photon number distributions Subject quantum opticsphoton statisticsquantum detectorssqueezed statesquantum information and processing To reference this document use: http://resolver.tudelft.nl/uuid:299142bc-2b72-47ce-b8da-b59e8c4c2834 DOI https://doi.org/10.1364/OE.19.024434 Publisher Optical Society of America ISSN 1094-4087 Source http://www.opticsinfobase.org/oe/abstract.cfm?URI=oe-19-24-24434 Source Optics Express, 19 (24), 2011 Part of collection Institutional Repository Document type journal article Rights (c) 2011 Optical Society of America Files PDF Dorenbos.pdf 1.38 MB Close viewer /islandora/object/uuid:299142bc-2b72-47ce-b8da-b59e8c4c2834/datastream/OBJ/view
