Atomic Quibits (IMAGE) University of Maryland Caption Strings of atomic qubits are used to probe quantum magnetism. Each row of bright lights and dark spots is a fluorescence snapshot of the atom string. Physicists use lasers to measure the qubits during the quantum simulation. The result, either dark or bright, allows them to extract information about the magnetic state of the system. Credit Data: J. Zhang et al.; graphic: E.
