Quantum computers, computer systems that leverage the laws of quantum mechanics, store and process information using qubits (i.e., quantum bits). In many quantum computers, qubits are linked via entanglement, a quantum mechanical effect that connects particles in such a way that their shared state cannot be described as separate, independent states.

Physicists just found the ‘ghost’ of superconductivity
Physicists have found striking evidence for an unusual form of superconducting behavior in uranium ditelluride, where electron pairs organize into rippling patterns called pair density waves. Even more surprisingly, these patterns appear to survive after ordinary superconductivit
