Quantum 6, 858 (2022). https://doi.org/10.22331/q-2022-11-10-858 I show that if a finite-dimensional density matrix has strictly smaller von Neumann entropy than a second one of the same dimension (and the rank is not bigger), then sufficiently […]
Quantum 6, 857 (2022). https://doi.org/10.22331/q-2022-11-10-857 In this letter, we propose how to measure the quantized nonlinear transport using two-dimensional ultracold atomic Fermi gases in a harmonic trap. This scheme requires successively applying two optical pulses […]
Quantum 6, 856 (2022). https://doi.org/10.22331/q-2022-11-10-856 We systematically investigate the robustness of symmetry protected topological (SPT) order in open quantum systems by studying the evolution of string order parameters and other probes under noisy channels. We […]
How can we navigate airliners or allow military vehicles to stay on course without GPS or satellite signals? This is a problem for which quantum inertial sensors offer a solution. Harnessing quantum technology, they can […]
Artificial intelligence algorithms cannot keep growing at their current pace. Algorithms like deep neural networks — which are loosely inspired by the brain, with multiple layers of artificial neurons linked to each other via numerical […]
Quantum 6, 855 (2022). https://doi.org/10.22331/q-2022-11-10-855 Even after decades of quantum computing development, examples of generally useful quantum algorithms with exponential speedups over classical counterparts are scarce. Recent progress in quantum algorithms for linear-algebra positioned quantum […]
Insider Brief: The Quantum Communications Hub has selected the Dutch company ISISPACE Group (ISISPACE) as the provider of satellite systems and services in support of the Hub’s In Orbit Demonstration (IOD) mission to demonstrate the […]
Electrons—those little subatomic particles that help make up the atoms in our bodies and the electricity flowing through your phone or computer right now—have some properties like mass and charge that will be familiar to […]
A team of researchers at Universität Heidelberg has built an early universe analog in their laboratory using chilled potassium atoms. In their paper published in the journal Nature, the group describes their simulator and how […]
Insider Brief Professor Elham Kashefi was appointed as The National Quantum Computing Centre’s (NQCC) Chief Scientist. Kashefi is Professor of Quantum Computing at the School of Informatics, University of Edinburgh, and Directeur de recherche au […]
