Quantum state smoothing: why the types of observed and unobserved measurements matter

Quantum state smoothing: why the types of observed and unobserved measurements matter

We investigate the estimation technique called quantum state smoothing introduced in (Guevara and Wiseman 2015 Phys. Rev. Lett. 115 180407), which offers a valid quantum state estimate for a partially monitored system, conditioned on the observed record both prior and posterior to an estimation time...
