The Petz recovery map for optical losses
Jinyan Chen, Minjeong Song, Jared Jia Xuan Chan +1
Optical systems are a main platform for quantum information processing. A main challenge is information loss due to scattering in unmonitored modes. These losses are modeled as sta…

Exact and approximate conditions of tabletop reversibility: when is Petz recovery cost-free?
Minjeong Song, Hyukjoon Kwon, Valerio Scarani
Channels that describe open quantum dynamics are inherently irreversible: it is impossible to undo their effect completely, but one can study partial recovery of the…
