Abstract: The disclosure includes a multiplexed telecommunication-band quantum network that utilizes atomic arrays in optical cavities. An example quantum networking system includes at least one quantum repeater node. The quantum repeater node includes an array of neutral atoms disposed in an optical cavity and a fiber-optic switch (FOS). The FOS is optically coupled to the optical cavity. The quantum repeater node also includes at least one beamsplitter. The at least one beamsplitter is optically coupled to the FOS.

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: A system for optically modulating a plurality of optical channels includes a power delivery module adapted to convert a coherent light beam into a plurality of optical channels, at least one optical modulator, optically coupled to the power delivery module, the at least one optical modulator adapted to optically modulate each of the plurality of the optical channels, and a vacuum chamber having a trapping plane therein, the vacuum chamber adapted to generate an addressable array of trapped particles at the trapping plane, wherein each of the plurality of optical channels is optically coupled to at least one of the trapped particles of the addressable array.

Abstract: A method of generating uniform large-scale optical focus arrays (LOT As) with a phase spatial light modulator 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 Gerch-berg-Saxton algorithm. The method also enables a faster compensation of optical system-induced LOT A intensity inhomogeneity than the conventional IFTA.

Abstract: A device for achieving multi-photon interference is provided based on nitrogen-vacancy defects in diamond material. Nitrogen-vacancy defects having a narrow band width and a similar emission frequency are identified within a high quality diamond material. The device has an excitation arrangement configured to individually address nitrogen-vacancy defects and optical outcoupling structures for increasing outcoupling of photons from each nitrogen-vacancy defect. A tuning arrangement is configured to tune the emission from each nitrogen-vacancy defect to reduce differences in frequency and the photons are overlapped. A detector is provided to detect the photon emissions. The detector is configured to resolve sufficiently small differences in photon detection times such that tuned photon emissions from the nitrogen-vacancy defects are quantum mechanically indistinguishable resulting in quantum interference between indistinguishable photon emissions from different nitrogen-vacancy defects.
