Qubit reset beyond the Born-Markov approximation: optimal driving to overcome polaron formation
Carlos Ortega-Taberner, Eoin O'Neill, Paul Eastham
Qubits are typically reset into a known state by coupling them to a low-temperature environment. When treated in the Born-Markov approximation such couplings produce exponential re…
Quantum control of the environment in open quantum systems enables rapid qubit reset
Carlos Ortega-Taberner, Eoin O'Neill, Paul Eastham
Qubit reset is crucial in quantum technology and is typically achieved by coupling the qubit to a dissipative environment. However, the achievable speed and fidelity are limited by…
Photon condensation from thermal sources and the limits of heat engines
Luisa Toledo Tude, Emily Haughton, Paul R. Eastham
The trapping and cooling of photon gases in microcavities has been used to create Bose-Einstein condensates. We investigate the conditions required for condensation in dye-filled m…
Overcoming temperature limitations in laser cooling using dressed states and diamond vacancies
Paul R. Eastham, Conor N. Murphy, Luisa Toledo Tude
The established approach to laser cooling of solids relies on anti-Stokes fluorescence, for example from rare earth impurities in glass. Although successful, there is a minimum tem…
Unifying methods for optimal control in non-Markovian quantum systems via process tensors
Carlos Ortega-Taberner, Eoin O'Neill, Eoin Butler +2
The large dimensionality of environments is the limiting factor in applying optimal control to open quantum systems beyond Markovian approximations. Multiple methods exist to simul…
Quantum thermodynamics of driven-dissipative condensates
Luisa Toledo Tude, Paul R. Eastham
Polariton condensates occur away from thermal equilibrium, in an open system where heat and particles are continually exchanged with reservoirs. These phenomena have been extensive…
