Superconductors, as physical systems, are materials that, below a critical temperature, exhibit exactly zero DC electrical resistance and expel interior magnetic fields via the Meissner effect, indicating a thermodynamic phase distinct from ordinary conductors. Their behavior is described microscopically by Bardeen–Cooper–Schrieffer (BCS) theory for conventional superconductors, where electrons form Cooper pairs that condense into a macroscopic quantum state with a complex order parameter and an energy gap in the excitation spectrum. Superconductors also display quantization of magnetic flux, support dissipationless supercurrents, and exhibit rich phase diagrams influenced by temperature, magnetic field, and material structure.
The fundamentals of quantum mechanics are minuscule. Scientists constantly home in on finer resolutions to measure, quantify, and control these fundamentals, like photons that carry light and have no mass unless they are ...

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, known as Cooper pairs.
Scientists have discovered the cause of a persistent glitch that continues to disrupt superconducting quantum computers, even when they have built-in defenses. For all their advanced hardware, superconducting quantum computers ...
