In recent years, many physicists and computer scientists have been working on the development of quantum computing technologies. These technologies are based on qubits, the basic units of quantum information.
Researchers at Stanford University have recently carried out an in-depth study of nematic transitions in iron pnictide superconductors. Their paper, published in Nature Physics, presents new imaging data of these transitions ...
(Phys.org) —In one of the tiniest switches ever made, five atoms appear to "dance" around each other in a complex choreographic sequence, with their final arrangement corresponding to one of two stable states. This concerted ...
(Phys.org)—For many electronic devices, colder is better. At low temperatures, electronic devices such as sensors and detectors operate with a higher efficiency and better overall performance than they do at room temperature. ...
(Phys.org)—Biological systems are characterized by a form of molecular recycling – and proteins do not escape this fate. In particular, unneeded or damaged proteins biochemically marked for destruction undergo controlled ...
Antiferromagnets have zero net magnetization and are insensitive to external magnetic field perturbations. Antiferromagnetic spintronic devices hold great promise for creating future ultra-fast and energy-efficient information ...
