Paper accepted to Phys. Rev. Lett. by Josh Combes, me, and Kurt Jacobs, "Rapid Measurement of Quantum Systems using Feedback Control" (arXiv:0712.3620)


We say farewell to Dr Jay Gambetta (off to Waterloo), and welcome a new postdoc, Dr Eric Cavalcanti, formerly from the University of Queensland.

Paper accepted to Nature! Entitled "Entanglement-Free Heisenberg-Limited Phase Estimation" (quant-ph/0709.2996) it was authored by me, with fellow-theoreticians Steve Bartlett (Sydney) and Dominic Berry (Macquarie) and experimentalists in our Centre for Quantum Dynamics: Geoff Pryde and his student Brendon Higgins. It reports the first-ever experimental demonstration of a phase measurement operating at the fundamental limit allowed by quantum mechanics.
