Demonstration of near-Optimal Discrimination of Optical Coherent States
C. Wittmann, M. Takeoka, K. N. Cassemiro +3
The optimal discrimination of non-orthogonal quantum states with minimum error probability is a fundamental task in quantum measurement theory as well as an important primitive in…
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…
