Photonic Circuits to Program Atoms at Scale

How do we control large numbers of qubits? This is a question being asked across quantum information science, including for atomic qubits. Unlike other varieties of qubits—such as superconducting qubits, where control signals are primarily electrical—atomic qubits are controlled by beams of light. Individual control over each atomic qubit requires modulating many individual optical beams....
