Symmetrical clock synchronization with time-correlated photon pairs
Jianwei Lee, Lijiong Shen, Alessandro Cerè +3
We demonstrate a point-to-point clock synchronization protocol based on bidirectionally exchanging photons produced in spontaneous parametric down conversion (SPDC). The technique…
Non-classical Correlations in n-Cycle Setting
Kishor Bharti, Maharshi Ray, Leong Chuan Kwek
We explore non-classical correlations in n-cycle setting. In particular, we focus on correlations manifested by Kochen-Specker-Klyachko box (KS box), scenarios involving n-cycle no…
Single-shot quantum memory advantage in the simulation of stochastic processes
Farzad Ghafari, Nora Tischler, Jayne Thompson +7
Stochastic processes underlie a vast range of natural and social phenomena. Some processes such as atomic decay feature intrinsic randomness, whereas other complex processes, e.g.…
Single atom energy-conversion device with a quantum load
Noah Van Horne, Dahyun Yum, Tarun Dutta +4
This work reports the functioning of a single atom energy-conversion device, operating either as a quantum engine or a refrigerator, coupled to a quantum load. The "working fluid"…
Genuine multipartite indistinguishability and its detection via generalized Hong-Ou-Mandel effect
Marcin Karczewski, Robert Pisarczyk, Paweł Kurzyński
The question whether two indistinguishable particles are bosons or fermions can be answered by observing the Hong-Ou-Mandel effect on a beam splitter. However, already for three pa…
Quantum Synchronisation in Nanoscale Heat Engines
Noufal Jaseem, Michal Hajdušek, Vlatko Vedral +3
Owing to the ubiquity of synchronization in the classical world, it is interesting to study its behavior in quantum systems. Though quantum synchronisation has been investigated in…
