Dynamics-based nonclassicality witness under dissipative dynamics
Nguyen Vu Khoi Huynh, Nicky Nel Narido Labayna, Martine Schut +1
A dynamics-based test, originally proposed by Tsirelson for the harmonic oscillator, provides a method for certifying quantumness under the assumption of a known Hamiltonian. These…
Cluster-State Witnesses of Finite-Speed Hidden Influences
Weikang Li, Mengyao Hu, Dong-Ling Deng +1
Bell experiments rule out local common-cause explanations of quantum correlations, yet they do not exclude hidden influences that travel faster than light while still having a fini…
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…
Kochen-Specker nonlocal hidden variables must include time-ordering to allow for measurement independence of several agents
Valerio Scarani, Antoine Suarez
We consider an ontology, in which contextual nonlocal hidden variables are stored as pre-existing possibilities in a repository outside space-time; and in which the context can be…
Sub-Bath Cooling in Bosonic Systems: Gaussian Constraints and Non-Gaussian Enhancements
Wen-Han Png, Xueyuan Hu, Valerio Scarani
Cooling quantum systems with finite resources is a central task in quantum technologies and has been extensively explored in discrete-variable settings. As continuous-variable (CV)…
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…
