Measuring Quantum Optical Hamiltonians
Giacomo Mauro D’Ariano, Lorenzo Maccone · Physical Review Letters · 1998
We show how recent state-reconstruction techniques can be used to determine the Hamiltonian of an optical device that evolves the quantum state of radiation. A simple experimental setup is proposed for measuring the Liouvillian of phase-insensitive devices. The feasibility of the method with current technology is demonstrated on the basis of Monte Carlo simulated experiments.
