Demonstration of deterministic and high fidelity squeezing of quantum information
Jun-ichi Yoshikawa, Toshiki Hayashi, Takayuki Akiyama +4
By employing at recent proposal (R. Filip, P. Marek and U.L. Andersen, Phys. Rev. A {\bf 71}, 042308 (2005) \cite{Filip05.pra}), we experimentally demonstrate a universal, determin…
Time domain Einstein-Podolsky-Rosen correlation
Nobuyuki Takei, Noriyuki Lee, Daiki Moriyama +2
We experimentally demonstrate creation and characterization of Einstein-Podolsky-Rosen (EPR) correlation between optical beams in the time domain. The correlated beams are created…
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…
High-fidelity teleportation beyond the no-cloning limit and entanglement swapping for continuous variables
Nobuyuki Takei, Hidehiro Yonezawa, Takao Aoki +1
We experimentally demonstrate continuous-variable quantum teleportation beyond the no-cloning limit. We teleport a coherent state and achieve the fidelity of 0.700.02 that sur…
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…
Experimental verification of a fully inseparable tripartite continuous-variable state
Takao Aoki, Nobuyuki Takei, Hidehiro Yonezawa +4
A continuous-variable tripartite entangled state is experimentally generated by combining three independent squeezed vacuum states and the variances of its relative positions and t…
