Decoherence-free quantum information in the presence of dynamical evolution (2008)
Brooke, Peter G., Cresser, James D., Patra, Manas K.
We analyze decoherence-free (DF) quantum information in the presence of an arbitrary non-nearest-neighbor bath-induced system Hamiltonian using a Markovian master equation. We show that the most...
Super- and subradiant emission of two-level systems in the near-Dicke limit (2007)
Brooke, Peter G., Marzlin, Karl-Peter, Cresser, James D., Sanders, Barry C.
We analyze the stability of super- and subradiant states in a system of identical two-level atoms in the near-Dicke limit, i.e., when the atoms are very close to each other compared to the wavelength...
Measurement master equation (2006)
Cresser, James D., Barnett, Stephen M., Jeffers, John, Pegg, David T.
We derive a master equation describing the evolution of a quantum system subjected to a sequence of observations. These measurements occur randomly at a given rate and can be of a very general form....

From measurements to quantum friction (2006)
Barnett, Stephen M, Jeffers, John, Cresser, James D
We present a quantum theory of friction in which interactions with the surrounding medium are described by generalized measurements of the particle's position and momentum. The theory predicts...
Geometric phase for an adiabatically evolving open quantum system (2004)
Kamleitner, Ingo, Cresser, James D., Sanders, Barry C.
We derive an elegant solution for a two-level system evolving adiabatically under the influence of a driving field with a time-dependent phase, which includes open system effects such as dephasing...
Completely positive maps with memory (2003)
Daffer, Sonja, Wodkiewicz, Krzysztof, Cresser, James D., McIver, John K.
The prevailing description for dissipative quantum dynamics is given by the Lindblad form of a Markovian master equation, used under the assumption that memory effects are negligible. However, in...
