Team from ETH Zurich make high quality quantum swap gate using a geometric phase
Researchers at ETH Zurich have realised particularly stable quantum logical operations with qubits made of neutral atoms. Since these operations, called quantum gates, are based on geometric phases they are extremely robust against experimental noise and can be used in quantum computers in the future.
