Experimental Tabletop Petz recovery of a photonic qubit
Hui Li, Jinyan Chen, Yue Pan +4
The quantum information lost in open evolutions cannot be fully recovered, but partial recovery is possible. The Petz recovery map guarantees almost optimal recovery, notably if th…

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…

Even-parity precession protocol for detecting nonclassicality and entanglement
Jinyan Chen, Jackson Tiong, Lin Htoo Zaw +1
We introduce an even-parity precession protocol that can detect the nonclassicality of some quantum states using only measurements of a uniformly-precessing variable at different p…
