Entropic uncertainties for joint quantum measurements
Thomas Brougham, Erika Andersson, Stephen M Barnett
We investigate the uncertainty associated with a joint quantum measurement of two components of spin of a spin-1/2 particle and quantify this in terms of entropy. We consider two e…
Momentum exchange between light and a single atom: Abraham or Minkowski?
E. A. Hinds, Stephen M. Barnett
We consider the forces exerted by a pulse of plane-wave light on a single atom. The leading edge of the pulse exerts a dispersive force on the atom, and this modifies the atomic mo…
Upper bounds on fault tolerance thresholds of noisy Clifford-based quantum computers
M. B. Plenio, S. Virmani
We consider the possibility of adding noise to a quantum circuit to make it efficiently simulatable classically. In previous works this approach has been used to derive upper bound…
Quantum state discrimination
Stephen M. Barnett, Sarah Croke
It is a fundamental consequence of the superposition principle for quantum states that there must exist non-orthogonal states, that is states that, although different, have a non-z…
On the conditions for discrimination between quantum states with minimum error
Stephen M. Barnett, Sarah Croke
We provide a simple proof for the necessity of conditions for discriminating with minimum error between a known set of quantum states.
Finding the Kraus decomposition from a master equation and vice versa
Erika Andersson, Jim D. Cresser, Michael J. W. Hall
For any master equation which is local in time, whether Markovian, non-Markovian, of Lindblad form or not, a general procedure is reviewed for constructing the corresponding linear…
