Quantum systems never quite forget where they came from

Even the most chaotic quantum systems keep a permanent mark of their own past—a "quantum birthmark"—that never fades. Researchers from Tampere University, Harvard University and TU Dresden discovered the feature in their ...

Superfluid qubit could help scale up quantum computers

Superfluid helium could offer a new way to tackle one of the biggest challenges in scaling up quantum computers, say researchers from the University of Surrey. The research team has introduced a conceptual design for a new ...
