Quantum Control With Light Paves Way For Ultra-Fast Computers

control

Terahertz light can control some of the essential quantum properties of superconducting states, report researchers. Jigang Wang patiently explains his latest discovery in quantum control that could lead to superfast computing based on quantum mechanics: He mentions light-induced superconductivity without energy gap. He brings up forbidden supercurrent quantum beats. And he mentions terahertz-speed symmetry breaking. …

Two-Dimensional Boron Is A Low-temperature Superconductor

2d boron superconductor

Two-dimensional boron is a natural low-temperature superconductor, Rice University scientists have established. In fact, it may be the only 2-D material with such potential. Rice theoretical physicist Boris Yakobson and his co-workers published calculations that show atomically flat boron is metallic and will transmit electrons with no resistance. The catch, as with most superconducting materials, …

Iron Selenide Thin Films For High-temperature Superconductivity

iron selenium thin film superconductor

An atomically thin, high-temperature superconductor film has been created, by researchers group Tohoku University, which has a superconducting transition temperature (Tc) of up to 60 K (-213°C). Superconductors are looked on as being among the most promising technologies for next-generation advanced electronic devices. This because the special quantum effects in superconductors are a big advantage …

High-Temperature Superconductors Investigated with Mira Supercomputer

iron selenide

Researchers from the University of Illinois at Urbana-Champaign (UIUC) are using supercomputing resources at the Argonne Leadership Computing Facility (ALCF), a DOE Office of Science User Facility, to shed light on the mysterious nature of high-temperature superconductors. With critical temperatures ranging from 30 Kelvin to 130 Kelvin (405 degrees below zero to 225 degrees below …
