Scientists at the U. S. Department of Energy Ames National Laboratory and Iowa State University have discovered an unexpected "quantum echo" in a superconducting material. This discovery provides ...

Superconductors are materials that can conduct electricity with a resistance of zero. In so-called conventional superconductors, this occurs at low temperatures when electrons become bound into pairs, ...

Josephson junction structures—quantum devices made of two superconductors and a thin non-superconducting barrier—using different forms of germanium (Ge): super-Ge (in gold), semiconducting Ge (in blue ...

Superconductors sit at the heart of some of the most ambitious technologies on the horizon, from lossless power grids to practical quantum computers, yet finding new ones has long been a slow, ...

UNIVERSITY PARK, PA. — Electricity flows through wires to deliver power, but it loses energy as it moves, delivering less than it started with. But that energy loss isn’t a given. Scientists at Penn ...

During electrical conduction, resistance leads to energy loss. However, at a critical temperature, superconductors conduct electricity with zero resistance; that is, they conduct direct electricity ...

Physicists measured how readily a current of electron pairs flows through 'magic-angle' graphene, a major step toward understanding how this unusual material superconducts. By determining how readily ...

Graphitic materials have emerged as a versatile platform for the study of unconventional superconductivity. Beyond purely crystalline graphene, naturally occurring graphite and highly oriented ...

Superconductivity is a fascinating phenomenon in which certain materials exhibit zero electrical resistance and expel magnetic fields below a characteristic temperature, known as the critical ...

Quantum bits (qubits) are the fundamental building blocks of quantum information processing. A novel qubit platform invented ...

Scientists link quantum theory with superconductivity, offering a way to predict materials that could enable resistance-free power at higher temperatures. (Nanowerk News) Electricity flows through ...
