Squeezing at 946nm with periodically-poled KTiOPO_4
Takao Aoki, Go Takahashi, Akira Furusawa
We report generation of squeezed vacuum in sideband modes of continuous-wave light at 946 nm using a periodically poled KTiOPO_4 crystal in an optical parametric oscillator. At the…
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…
