Systems based on atom and atom-like quantum emitters are promising platforms for quantum sensing, computing, and communications. State-of-the-art lasers and optical microscopy enable high-fidelity quantum control of the atomic quantum bits (qubits). However, it is challenging to scale up such individual quantum control to hundreds or thousands of 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 for various applications. These methods enable implementation of quantum circuits over large 2D and 3D 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.

A hybrid system and method for recording wave fronts of light. This system combines elements of two imaging systems, Holography and Integral imaging, to produce an imaging system that has higher efficiency and better resolution than Integral imaging, and few of the limitations of holographic recording.

A volume holographic film (such as a photopolymer) that is pre-recorded with patterns subsequently is used to encode LED or low-power laser light reflections from an eye into a binary pattern that can be read at very high speeds by a relatively simple complementary metal-oxide-semiconductor (CMOS) sensor that may be similar to a high framerate, low resolution mouse sensor. The low-resolution mono images from the film are translated into eye poses using, for instance, a look up table that correlates binary patterns to X, Y positions or using a pre-trained convolutional neural network to robustly interpret many variations of the binary patterns for conversion to X, Y positions.

According to one embodiment, there is provided an optical film with a recording surface, the recording surface including: a computation element section in which a phase component of light from each reconstruction point of a reconstructed image is computed, the computation element section corresponding to each reconstruction point one by one; a phase angle recording area in which a phase angle computed based on the phase component is recorded; and a phase angle non-recording area in which the phase angle is not recorded, the phase angle computed based on the phase component being recorded in an overlapping area where the computation element section and the phase angle recording area overlap each other.

Holographic and diffractive optical encoding techniques for forming reflection or transmission holograms. The encoding device includes a substrate having an interference pattern that can propagate light along a light propagation path from one side of the substrate to another side of the substrate. Furthermore, an optical element may be used to propagate light according to a four-dimensional light field coordinate system.

A holographic display and a method, performed by the holographic display, of forming a holographic image are disclosed. The holographic display includes an electrically addressable spatial light modulator (EASLM); a diffractive optical element (DOE) mask array arranged on the EASLM; and a controller configured to operate the holographic display to form a hologram image, wherein the controller is further configured to address the EASLM to backlight the DOE mask array required to form a set of hologram image voxels by turning on a corresponding EASLM pixel.
