Superconductors allow electrical current to flow without any resistance – but only below a certain critical temperature. Many materials have to be cooled down to almost absolute zero, while some materials keep their superconducting properties up to much higher temperatures. How this “high-temperature superconductivity” works and how it is possible to develop new materials that Read more about Strange Metals as the Key to Superconductivity[…]
Employees of Kazan Federal University and Kazan Quantum Center of Kazan National Research Technical University demonstrated an original layout of a prototype of multiresonator broadband quantum memory-interface. Professor Sergey Moiseev, Director of Kazan Quantum Center, explains, “The scheme of multiresonator microwave quantum memory allowed for reaching 16.3% of quantum efficiency at room temperature, which was significantly Read more about Universal memory solutions for quantum computers on superconducting qubits[…]
Due to magnetism iron should – theoretically – be a poor superconductor. Nevertheless certain ironbased materials possess fine superconducting properties. Why? Because the five unbound electrons found in iron – as a result of individual modes of operation, it turns out – facilitate superconductivity. This new, long sought-for explanation – appearing in this weeks issue Read more about Iron secrets behind superconductors unlocked[…]
