Quantum computing is becoming the defining battleground of the 21st-century technological rivalry between the United States ...

The promise of so-called “quantum advantage” is simple. By harnessing the counterintuitive rules of quantum mechanics, ...

At the centre of the object is a small vacuum chamber that could hold a single trapped ion – which could be operated as a quantum engine. Lasers are pointed at the ions through the chamber windows and ...

Top panel: The surface code is divided into 5 regions, the central data qubit, regions I, II, III, and IV. The logical operators Z ̂_L and X ̂_L intersect at the central data qubits.
