Electronic coherence theory
Stephen D. Bartlett, Barry C. Sanders, William D. Oliver +1
We withdraw our paper as the factorizability of the correlation functions is unproven.
Optimal measurements for relative quantum information
Stephen D. Bartlett, Terry Rudolph, Robert W. Spekkens
We provide optimal measurement schemes for estimating relative parameters of the quantum state of a pair of spin systems. We prove that the optimal measurements are joint measureme…
Direct observation of non-classical photon statistics in parametric downconversion
Edo Waks, Eleni Diamanti, Barry C. Sanders +2
We employ a high quantum efficiency photon number counter to determine the photon number distribution of the output field from a parametric downconverter. The raw photocount data d…
Photon-number superselection and the entangled coherent-state representation
Barry C. Sanders, Stephen D. Bartlett, Terry Rudolph +1
We introduce the entangled coherent state representation, which provides a powerful technique for efficiently and elegantly describing and analyzing quantum optics sources and dete…
Entanglement constrained by superselection rules
Stephen D. Bartlett, H. M. Wiseman
Bipartite entanglement may be reduced if there are restrictions on allowed local operations. We introduce the concept of a generalized superselection rule (SSR) to describe such re…
Semigroup techniques for the efficient classical simulation of optical quantum information
Stephen D. Bartlett
A framework to describe a broad class of physical operations (including unitary transformations, dissipation, noise, and measurement) in a quantum optics experiment is given. This…
