Continuous Variable Quantum State Sharing via Quantum Disentanglement
Andrew M. Lance, Thomas Symul, Warwick P. Bowen +4
Quantum state sharing is a protocol where perfect reconstruction of quantum states is achieved with incomplete or partial information in a multi-partite quantum networks. Quantum s…
Optimum Small Optical Beam Displacement Measurement
Magnus T. L. Hsu, Vincent Delaubert, Ping Koy Lam +1
We derive the quantum noise limit for the optical beam displacement of a TEM00 mode. Using a multimodal analysis, we show that the conventional split detection scheme for measuring…
Squeezing in the audio gravitational wave detection band
K. McKenzie, N. Grosse, W. P. Bowen +4
We demonstrate the generation of broad-band continuous-wave optical squeezing down to 200Hz using a below threshold optical parametric oscillator (OPO). The squeezed state phase wa…
Quantum Cryptography without Switching
Christian Weedbrook, Andrew M. Lance, Warwick P. Bowen +3
We propose a new coherent state quantum key distribution protocol that eliminates the need to randomly switch between measurement bases. This protocol provides significantly higher…
