Trading energy for coherence in mode discrimination
Shuyang Meng, Valerio Scarani
Energy is arguably the main resource in classical physics; coherence is the prototypical quantum resource. In this paper, we study the interplay between these two resources in the…
Experimental certification of multipartite Bell correlations using only few-body symmetric correlations
Jiacheng Sun, Mengyao Hu, Paweł Cieśliński +9
Certifying Bell correlations in increasingly larger multipartite quantum systems is challenging because conventional Bell inequalities rely on many-body correlations, which become…
Tsirelson's 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…
