When a photon interacts with a material, an interaction occurs that causes its atoms to change their quantum state (a description of the physical properties of nature at the atomic level). The resulting state is […]
Fermion production at the boundary of an expanding universe: a cold-atom gravitational analogue0 (0)
Quantum 7, 1042 (2023). https://doi.org/10.22331/q-2023-06-21-1042 We study the phenomenon of cosmological particle production of Dirac fermions in a Friedmann-Robertson-Walker spacetime, focusing on a $(1+1)-$dimensional case in which the evolution of the scale factor is set […]
The discovery of the quantum Hall effects in the 1980s revealed the existence of novel states of matter called “Laughlin states,” in honor of the American Nobel prize winner who successfully characterized them theoretically. These […]
On a Saturday afternoon in the fall of 2021, Silvio Decurtins was leafing through a paper with a title that could have been pulled from a comic book for mathematically inclined teens: “Plato’s Cube and […]
Researchers at MPQ in Garching, together with a team from TU Munich, have excited erbium atoms embedded in crystalline silicon such that they emit single photons. Their special properties can form the basis for the […]
The School of Informatics, University of Edinburgh invites applications for two research assistant position for two years funded by EPSRC to work on the Benchmarking Quantum Advantage at the recently created Quantum Software Lab, the […]
Electrons inside crystals interact closely with phonons, defined as the discrete unit of crystal vibrations. The electron–phonon coupling strength is an important fundamental physical quantity in solid state physics, determining electrodynamic behaviors and correlated functionalities […]
Insider Brief PASQAL announces the creation of a factory to produce quantum processing devices at Espace Quantique 1 of DistriQ. The division will be called PASQAL-Canada and produce hardware for the North American market. PASQAL […]
A team led by Guo Guangcan from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) explored non-Markovian behaviors of Einstein-Podolsky-Rosen (EPR) steering in quantum processes and revealed […]
