Abstract: Smoothing is an estimation technique that takes into account both past andfuture observations, and can be more accurate than filtering alone. In thisLetter, a quantum theory of smoothing is constructed using a time-symmetricformalism, thereby generalizing prior work on classical and quantum filtering,retrodiction, and smoothing. The proposed theory solves the important problemof optimally estimating classical Markov processes coupled to a quantum systemunder continuous measurements, and is thus expected to find major applicationsin future quantum sensing systems, such as gravitational wave detectors andatomic magnetometers.
