Various applications for entanglement manipulations and multiphoton qubits are discussed.American Physical Society2002-03-26engjournal articleVoRhttp://hdl.handle.net/2115/5562http://www.aps.org/https://doi.org/10.1103/PhysRevLett.88.147901119551780031-9007Physical Review Letters88147901https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5562/1/PRL88-14.pdfapplication/pdf70.53 KB2002-03-26
