Coherent State Quantum Key Distribution Without Random Basis Switching
Christian Weedbrook, Andrew M. Lance, Warwick P. Bowen +3
The random switching of measurement bases is commonly assumed to be a necessary step of quantum key distribution protocols. In this paper we show that switching is not required for…
Harmonic entanglement with second-order non-linearity
Nicolai B. Grosse, Warwick P. Bowen, Kirk McKenzie +1
We investigate the second-order non-linear interaction as a means to generate entanglement between fields of differing wavelengths. And show that perfect entanglement can, in princ…
Continuous-Variable Spatial Entanglement for Bright Optical Beams
Magnus T. L. Hsu, Warwick P. Bowen, Nicolas Treps +1
A light beam is said to be position squeezed if its position can be determined to an accuracy beyond the standard quantum limit. We identify the position and momentum observables f…
