Experimental demonstration of quantum teleportation of a squeezed state
Nobuyuki Takei, Takao Aoki, Satoshi Koike +8
Quantum teleportation of a squeezed state is demonstrated experimentally. Due to some inevitable losses in experiments, a squeezed vacuum necessarily becomes a mixed state which is…
Implementation of generalized quantum measurements: superadditive quantum coding, accessible information extraction, and classical capacity limit
M. Takeoka, M. Fujiwara, J. Mizuno +1
Quantum information theory predicts that when the transmission resource is doubled in quantum channels, the amount of information transmitted can be increased more than twice by qu…
Exceeding classical capacity limit in quantum optical channel
Mikio Fujiwara, Masahiro Takeoka, Jun Mizuno +1
The amount of information transmissible through a communications channel is determined by the noise characteristics of the channel and by the quantities of available transmission r…
Experimental demonstration of quantum source coding
Y. Mitsumori, J. A. Vaccaro, S. M. Barnett +4
We report an experimental demonstration of Schumacher's quantum noiseless coding theorem. Our experiment employs a sequence of single photons each of which represents three qubits.…
Unambiguous quantum state filtering
Masahiro Takeoka, Masashi Ban, Masahide Sasaki
In this paper, we consider the generalized measurement where one particular quantum signal is unambiguously extracted from a set of non-commutative quantum signals and the other si…
