A Direct Coupling Coherent Quantum Observer for an Oscillatory Quantum Plant (1706.06248v1)
Published 20 Jun 2017 in quant-ph and cs.SY
Abstract: A direct coupling coherent observer is constructed for a linear quantum plant which has oscillatory solutions. It is shown that a finite time moving average of the quantum observer output can provide an estimate of the quantum plant output without disturbing this plant signal. By choosing a sufficiently small averaging time and a sufficiently large observer gain, the observer tracking error can be made arbitrarily small.
