In an experiment, the relative phase of two different LG modes of measurement basis states is manipulated via the Gouy phase, and the observed coincidence count rates agree well with theoretical predictions. This result suggests that the Gouy phase can be used as a new tool to manipulate multidimensional photonic quantum states.American Physical Society2008-08-01engjournal articleVoRhttp://hdl.handle.net/2115/49846https://doi.org/10.1103/PhysRevLett.101.050501187643800031-90071079-7114Physical Review Letters1015050501https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/49846/1/PRL101-5_050501.pdfapplication/pdf1.03 MB2008-08-01
