Retrodictive quantum optical state engineering
K. L. Pregnell, D. T. Pegg
Although it has been known for some time that quantum mechanics can be formulated in a way that treats prediction and retrodiction on an equal footing, most attention in engineerin…
Quantum nature of laser light
David T. Pegg, John Jeffers
All compositions of a mixed-state density operator are equivalent for the prediction of the probabilities of future outcomes of measurements. For retrodiction, however, this is not…
Single-shot measurement of quantum optical phase
K. L. Pregnell, D. T. Pegg
Although the canonical phase of light, which is defined as the complement of photon number, has been described theoretically by a variety of distinct approaches, there have been no…
Measuring the elements of the optical density matrix
K. L. Pregnell, D. T. Pegg
Most methods for experimentally reconstructing the quantum state of light involve determining a quasiprobability distribution such as the Wigner function. In this paper we present…
Master Equation for Retrodiction of Quantum Communication Signals
Stephen M. Barnett, David T. Pegg, John Jeffers +1
We derive the master equation that governs the evolution of the measured state backwards in time in an open system. This allows us to determine probabilities for a given set of pre…
