| The Necessity of Extending Quantum Prior Beliefs | TQC 2026 | regular ▸ presenter | Ge Bai, Valerio Scarani |
A mixed quantum state can be taken as describing the lack of knowledge about the true pure state of the system ("proper mixture"); or as arising from entanglement with another system that has been disregarded ("improper mixture"). We demonstrate that proper and improper mixtures, while indistinguishable for prediction, constitute distinct priors yielding inequivalent retrodictive updates. We introduce extended retrodiction to capture these latent correlations. This framework resolves the conflict in quantum smoothing, unifying the Guevara-Wiseman and Petz-Fuchs approaches as special cases of extended priors, and establishes their entropic relation. |
