MIT and Harvard researchers demonstrate qubit control using global fields for three-atom interaction

A team of researchers from MIT and Harvard has successfully demonstrated a novel method for controlling qubits using global fields, achieving a three-atom interaction (an effective ZXZ interaction) that extends beyond the typical two-atom limitations of Rydberg-atom arrays. This breakthrough in quantum control, achieved by breaking mirror symmetry, suggests that global fields can support richer quantum dynamics and represents a significant advance in the field of quantum computing.
