Mixed Quantum-Classical Dynamics Yields Anharmonic Rabi Oscillations
Ming-Hsiu Hsieh, Roel Tempelaar
We apply a mixed quantum-classical (MQC) approach to the quantum Rabi model, involving a classical optical field coupled self-consistently to a quantum two-level system. Under the…

Unitary Basis Transformations in Mixed Quantum-Classical Dynamics
Ken Miyazaki, Alex Krotz, Roel Tempelaar
A common approach to minimizing the cost of quantum computations is by transforming a quantum system into a basis that can be optimally truncated. Here, we derive classical equatio…

Perturbation theory under the truncated Wigner approximation reveals how system-environment entanglement formation drives quantum decoherence
Justin Provazza, Roel Tempelaar
Quantum decoherence is the disappearance of simple phase relations within a discrete quantum system as a result of interactions with an environment. For many applications, the ques…
