Generation of large-amplitude coherent-state superposition via ancilla-assisted photon-subtraction
Hiroki Takahashi, Kentaro Wakui, Shigenari Suzuki +4
We propose and demonstrate a novel method to generate a large-amplitude coherent-state superposition (CSS) via ancilla-assisted photon-subtraction. The ancillary mode induces quant…
Temporally multiplexed superposition states of continuous variables
Masahide Sasaki, Masahiro Takeoka, Hiroki Takahashi
We study non-Gaussian states generated by two-photon subtraction from a cw squeezed light source. In a cw scheme one can subtract two photons from the source with a designated time…
Large amplitude coherent state superposition generated by a time-separated two-photon subtraction from a continuous wave squeezed vacuum
Masahiro Takeoka, Hiroki Takahashi, Masahide Sasaki
Theoretical analysis is given for a two-photon subtraction from a continuous wave (CW) squeezed vacuum with finite time separation between two detection events. In the CW photon su…
Demonstration of quantum telecloning of optical coherent states
Satoshi Koike, Hiroki Takahashi, Hidehiro Yonezawa +4
Quantum cryptography promises in-principle secure communication between two parties via a quantum channel, with the ability to discover eavesdropping when it occurs. In 1999, a tel…
