Abstract: A method of generating uniform large-scale optical focus arrays (LOT As) with a phase spatial light modulator (SLM) includes identifying and removing undesired phase rotation in the iterative Fourier transform algorithm (IFTA), thereby producing computer-generated holograms of highly uniform LOT As using a reduced number of iterations as compared to a weighted Gerchberg-Saxton algorithm. The method also enables a faster compensation of optical system-induced LOT A intensity inhomogeneity than the conventional IFTA.

Abstract: Systems and methods relate to arranging atoms into 1D and/or 2D arrays; exciting the atoms into Rydberg states and evolving the array of atoms, for example, using laser manipulation techniques and high-fidelity laser systems described herein; and observing the resulting final state. In addition, refinements can be made, such as providing high fidelity and coherent control of the assembled array of atoms. Exemplary problems can be solved using the systems and methods for arrangement and control of atoms.

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.

Abstract: The Zeeman shift of electronic spins in nitrogen-vacancy (NV) centers in diamond has been exploited in lab-scale instruments for ultra-high-resolution, vector-based magnetic sensing. A quantum magnetometer in CMOS utilizing a diamond-nanocrystal layer with NVs or NV-doped bulk diamond on a chip-integrated system provides vector-based magnetic sensing in a compact package. The system performs two functions for the quantum magnetometry: (1) strong generation and efficient delivery of microwave for quantum-state control and (2) optical filtering/detection of spin-dependent fluorescence for quantum-state readout. The microwave delivery can be accomplished with a loop inductor or array of wires integrated into the chip below the nanodiamond layer or diamond. And the wire array can also suppress excitation light using a combination of plasmonic and (optionally) Talbot effects.
