Entanglement quantification with Fisher information
Akira kitagawa, Masahiro Takeoka, Masahide Sasaki +1
We show that the Fisher information associated with entanglement-assisted coding has a monotonic relationship with the logarithmic negativity, an important entanglement measure, fo…
Controllable generation of highly nonclassical states from nearly pure squeezed vacua
K. Wakui, H. Takahashi, A. Furusawa +1
We present controllable generation of various kinds of highly nonclassical states of light, including the single photon state and superposition states of mesoscopically distinct co…
Binary projective measurement via linear optics and photon counting
Masahiro Takeoka, Masahide Sasaki, Norbert Lütkenhaus
We investigate the implementation of binary projective measurements with linear optics. This problem can be viewed as a single-shot discrimination of two orthogonal pure quantum st…
EPR Beams and Photon Number Detector: Toward Synthesizing Optical Nonlinearity
M. Sasaki, K. Wakui, J. Mizuno +2
We present the two kinds of experimental results. One is a continuous variable dense coding experiment, and the other is a photon number detector with high linearity response, the…
