Stable, scalable quantum gates using geometry-based neutral-atom qubits instead of fragile, dynamics-based operations

"quantum gates highly sensitive to noise/ imperfections, especially when based on tunneling/ atomic collisions where small laser fluctuations degrade performance... overcome using swap gate exchanging states of 2 qubits in <1 ms using geometric phase, a property that depends on particles' path rather than external conditions... highly robust against experimental noise since geometric phases don’t rely on precise timing/ laser intensity... ~99.9% accurate, applied simultaneously to 17K qubit pairs"
