Coherent feedback that beats all measurement-based feedback protocols
Kurt Jacobs, Xiaoting Wang, Howard M. Wiseman
We show that when the speed of control is bounded, there is a widely applicable minimal-time control problem for which a coherent feedback protocol is optimal, and is faster than a…
Experimental test of universal complementarity relations
Morgan M. Weston, Michael J. W. Hall, Matthew S. Palsson +2
Complementarity restricts the accuracy with which incompatible quantum observables can be jointly measured. Despite popular conception, the Heisenberg uncertainty relation does not…
Entanglement verification and steering when Alice and Bob cannot be trusted
Eric G. Cavalcanti, Michael J. W. Hall, Howard M. Wiseman
Various protocols exist by which a referee can be convinced that two observers share an entangled resource. Such protocols typically specify the types of communication allowed, and…
Quantum-enhanced optical phase tracking
Hidehiro Yonezawa, Daisuke Nakane, Trevor A. Wheatley +10
Tracking a randomly varying optical phase is a key task in metrology, with applications in optical communication. The best precision for optical phase tracking has till now been li…
Optimal Heisenberg-style bounds for the average performance of arbitrary phase estimates
Dominic W. Berry, Michael J. W. Hall, Marcin Zwierz +1
The ultimate bound to the accuracy of phase estimates is often assumed to be given by the Heisenberg limit. Recent work seemed to indicate that this bound can be violated, yielding…
Quantum discord is Bohr's notion of non-mechanical disturbance introduced in his answer to EPR
Howard M. Wiseman
By rigorously formalizing the Einstein-Podolsky-Rosen (EPR) argument, and Bohr's reply, one can appreciate that both arguments were technically correct. Their opposed conclusions a…
