Scientists say they’ve cracked a key challenge in scalable quantum hardware after generating an error-correcting, light-based qubit on a chip for the first time.

Researchers at the Niels Bohr Institute, University of Copenhagen, have developed a tunable system that paves the way for ...

While randomising a deck of cards gets more difficult as you add more cards, it turns out that the same isn't true for the ...

Just over 200 years after French engineer and physicist Sadi Carnot formulated the second law of thermodynamics, an international team of researchers has unveiled an analogous law for the quantum ...

Two studies fill in gaps about the cosmos’s ordinary matter. One maps it all, even the “missing matter.” The other details one of its hiding spots.

Quantum tunnelling — when a particle skips through a barrier that classical physics would forbid — happens faster when objects have less energy, find physicists who worked out a way to probe photons ...

A new quantum recipe for black holes could be the first step toward a theory of "quantum gravity", the "holy grail" of ...

A research team has achieved the holy grail of quantum computing: an exponential speedup that’s unconditional. By using ...
