Quantum-classical crossover of a field mode
journal contribution
posted on 2009-03-30, 13:45 authored by Mark EverittMark Everitt, W.J. Munro, T.P. SpillerWe explore the quantum-classical crossover in the behaviour of a quantum field mode. The quantum behaviour
of a two-state system—a qubit—coupled to the field is used as a probe. Collapse and revival of the
qubit inversion form the signature for quantum behaviour of the field and continuous Rabi oscillations form the
signature for classical behaviour of the field. We demonstrate both limits in a single model for the full coupled
system, for field states with the same average field strength, and so for qubits with the same Rabi frequency.
