Adaptive Phase Measurements in Linear Optical Quantum Computation
T. C. Ralph, A. P. Lund, H. M. Wiseman
Photon counting induces an effective nonlinear optical phase shift on certain states derived by linear optics from single photons. Although this no nlinearity is nondeterministic,…
States for phase estimation in quantum interferometry
Joshua Combes, H. M. Wiseman
Ramsey interferometry allows the estimation of the phase of rotation of the pseudospin vector of an ensemble of two-state quantum systems. For small, the noise-to-signal ra…
Entanglement of identical particles and reference phase uncertainty
John A. Vaccaro, Fabio Anselmi, Howard M. Wiseman
We have recently introduced a measure of the bipartite entanglement of identical particles, E_P, based on the principle that entanglement should be accessible for use as a resource…
Precis: Quantum Feedback
H. M. Wiseman
The following is the body of page ix of the PhD thesis Quantum Trajectories and Feedback by H.M. Wiseman (Physics Department, University of Queensland, 1994), which is downloadable…
Comment on ``Testing integrability with a single bit of quantum information''
Howard M. Wiseman
In quant-ph/0303042, Poulin, Laflamme, Milburn and Paz consider the problem of distinguishing quantum chaos from quantum integrability for dynamics in an -dimensional Hilbert sp…
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…
