A NUST MISIS professor was part of an international research team that has found evidence for the existence of the Zeeman spin-orbit coupling in antiferromagnetic conductors. This work may pave the way for the next […]
The City is missing a trick. The City Corporation’s recovery and reinvention plan, published tomorrow, focuses on rebranding as a technology hub, the third point in the triangle between Oxford and Cambridge, with MedTech, Green […]
When you walk into a room full of people, you can speculate about all sorts of things, from political leanings to TV viewing habits. But if the room has at least six people, you can […]
Quantum 5, 444 (2021). https://doi.org/10.22331/q-2021-04-26-444 Device-independent quantum key distribution aims at providing security guarantees even when using largely uncharacterised devices. In the simplest scenario, these guarantees are derived from the CHSH score, which is a […]
Quantum 5, 443 (2021). https://doi.org/10.22331/q-2021-04-26-443 The simplest device-independent quantum key distribution protocol is based on the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality and allows two users, Alice and Bob, to generate a secret key if they observe […]

Einstein-Podolski-Rosen correlations can be used for precision measurements. (Image: Jurik Peter, Shutterstock) Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University […]
Building a computer that can support artificial intelligence at the scale and complexity of the human brain will be a colossal engineering effort. Now researchers at the National Institute of Standards and Technology have outlined […]
Quantum 5, 442 (2021). https://doi.org/10.22331/q-2021-04-26-442 We analyse orthogonal bases in a composite $Ntimes N$ Hilbert space describing a bipartite quantum system and look for a basis with optimal single-sided mutual state distinguishability. This condition implies […]
John Martinis is maybe best known as being a leader of Google’s team that developed the first quantum computer to vastly outperform a classical computer at a specific task, usually referred to as quantum supremacy. […]
