Quantum computing still stumbles on fragility, where tiny disturbances can wreck calculations. ETH Zurich researchers built a geometric swap gate with neutral atoms that stayed remarkably stable ...
Researchers at ETH Zurich have realized particularly stable quantum logical operations with qubits made of neutral atoms. Since these operations, called quantum gates, are based on geometric phases, ...
Physicists in the US have devised a way to swap the spin states of pairs of ultracold rubidium atoms in an optical lattice. The ability to switch individual spin states back and forth is an important ...
