OQuPy: A Python package to efficiently simulate non-Markovian open quantum systems with process tensors
Gerald E. Fux, Piper Fowler-Wright, Joel Beckles +11
Non-Markovian dynamics arising from the strong coupling of a system to a structured environment is essential in many applications of quantum mechanics and emerging technologies. De…
Synchronization and spacetime vortices in one-dimensional driven-dissipative condensates and coupled oscillator models
John P. Moroney, Paul R. Eastham
Driven-dissipative condensates, such as those formed from polaritons, expose how the coherence of Bose-Einstein condensates evolves far from equilibrium. We consider the phase and…
Optimizing performance of quantum operations with non-Markovian decoherence: the tortoise or the hare?
Eoin P. Butler, Gerald E. Fux, Carlos Ortega-Taberner +3
The interaction between a quantum system and its environment limits our ability to control it and perform quantum operations on it. We present an efficient method to find optimal c…
Overcoming temperature limits in the optical cooling of solids using light-dressed states
Luisa Toledo Tude, Conor N. Murphy, Paul R. Eastham
Laser cooling of solids currently has a temperature floor of 50 - 100 K. We propose a method that could overcome this using defects, such as diamond color centers, with narrow elec…
Laser Cooling Beyond Rate Equations: Approaches From Quantum Thermodynamics
C. N. Murphy, L. Toledo Tude, P. R. Eastham
Solids can be cooled by driving impurity ions with lasers, allowing them to transfer heat from the lattice phonons to the electromagnetic surroundings. This exemplifies a quantum t…
Quantum control of solid-state qubits for thermodynamic applications
Paul R. Eastham, Conor Murphy
We give an overview of our recent theoretical studies of the thermodynamics of excitons, and other solid-state qubits, driven by time-dependent laser fields. We consider a single s…
