Robust against noise, geometric-phase swap gates bring stability to quantum operations

Phys · · 887 words · By Oliver Morsch

Researchers at ETH Zurich have developed highly stable quantum gates using geometric phases with neutral atoms, making them robust against experimental noise. The technique allows for simultaneous operations on thousands of qubits and could advance quantum computing with neutral atoms.
