A Graphene Superconductor That Plays More Than One Tune

superconductivity in a trilayer graphene moiré superlattice

Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a graphene device that’s thinner than a human hair but has a depth of special traits. It easily switches from a superconducting material that conducts electricity without losing any energy, to an insulator that resists the flow of electric current, …

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. …

Quantum Computer And Mezzo Soprano To Duet In World First Performance

d-wave 2x

What happens when you combine the pure tones of an internationally renowned mezzo soprano and the complex technology of a $15 million quantum supercomputer? The answer will be exclusively revealed to audiences at the Port Eliot Festival when Superposition, created by Plymouth University composer Alexis Kirke, receives its world premiere later this summer. Combining the …
