Quantum 6, 882 (2022). https://doi.org/10.22331/q-2022-12-22-882 This paper is concerned with complexity theoretic aspects of a general formulation of quantum game theory that models strategic interactions among rational agents that process and exchange quantum information. In […]
We can think of a mathematician as a kind of archaeologist, painstakingly brushing dust off the hidden structures of the world. But the structures mathematicians reveal are not only durable, but also inevitable. They could […]
Quantum 6, 881 (2022). https://doi.org/10.22331/q-2022-12-22-881 Quantum machine learning techniques have been proposed as a way to potentially enhance performance in machine learning applications. In this paper, we introduce two new quantum methods for neural networks. […]
Quantum 6, 880 (2022). https://doi.org/10.22331/q-2022-12-22-880 The security of finite-length keys is essential for the implementation of device-independent quantum key distribution (DIQKD). Presently, there are several finite-size DIQKD security proofs, but they are mostly focused on […]
Positrons are anti-particles of electrons. At SuperKEKB B-Factory (SuperKEKB), they are produced in copious amounts and smashed into electrons at world-record luminosity. By studying the hundreds of decay patterns of B mesons and anti B […]
Insider Brief Fujitsu reports its quantum-inspired solution achieved excellent results in a Kutxabank project is to improve the allocation of assets to its investment portfolios. The algorithm made it possible to calculate the optimal distribution […]
The quantum industry was one of the few sectors that did not suffer a serious setback in capital market fund raising. The totals for 2022 nearly equaled the amount invested in 2021, which was a […]
The Superconducting Quantum Materials and Systems Center (SQMS), led by the Fermi National Accelerator Laboratory, is one of five elite National Quantum Initiative centers funded by the U.S. Department of Energy to research various areas […]
We are looking for a highly motivated and ambitious Ph.D. student in quantum condensed matter theory for a project on superconducting spintronics. The overall aim of the Ph.D. project is to theoretically explore and engineer […]
We see the world around us because light is being absorbed by specialized cells in our retina. But can vision happen without any absorption at all—without even a single particle of light? Surprisingly, the answer […]
