Entanglement evaluation of non-Gaussian states generated by photon subtraction from squeezed states
Akira Kitagawa, Masahiro Takeoka, Masahide Sasaki +1
We consider the problem of evaluating the entanglement of non-Gaussian mixed states generated by photon subtraction from entangled squeezed states. The entanglement measures we use…
Practical purification scheme for decohered coherent-state superpositions via partial homodyne detection
Shigenari Suzuki, Masahiro Takeoka, Masahide Sasaki +2
We present a simple protocol to purify a coherent-state superposition that has undergone a linear lossy channel. The scheme constitutes only a single beam splitter and a homodyne d…
Effective squeezing enhancement via measurement-induced non-Gaussian operation and its application to dense coding scheme
Akira Kitagawa, Masahiro Takeoka, Kentaro Wakui +1
We study the measurement-induced non-Gaussian operation on the single- and two-mode \textit{Gaussian} squeezed vacuum states with beam splitters and on-off type photon detectors, w…
Photon number squeezing of ultra-broadband laser pulses generated by microstructure fibers
K. Hirosawa, H. Furumochi, A. Tada +3
To the best of our knowledge, we demonstrate for the first time the generation of photon number squeezing by spectral filtering for ultra-broadband light generated by microstructur…
