Abstract
Atoms and atom-like quantum emitters are promising for quantum sensing, computing, and communications. Lasers and microscopes enable high-fidelity quantum control of the atomic quantum bits (qubits). However, it is challenging to scale up individual quantum control to enough atomic quantum nodes for implementing useful and practical quantum algorithms. Here, we introduce methods and systems to holographically implement large-scale quantum circuits that individually address atomic quantum nodes. These methods enable implementation of quantum circuits over large, multi-dimensional arrays of atomic qubits at rates of thousands to millions of quantum circuit layers per second. The quantum circuit layers are encoded in multiplexed holograms displayed on a slow SLM and retrieved by fast interrogation to produce spatial distributions that operate on the qubit array. This technology can also be used for optically addressing objects such as biological cells and on-chip photonic components for optical tweezers, opto-genetics, optical computing, and optical neural networks.
