Methods for generating Bose-Einstein condensates (BECs) and excitons at room temperature in certain materials, and enhancing lattice vibration that enhances fluid dynamics, catalyzing reactions, acoustics modification, optics and electronics modification, real-time combustion modification, optics enhancement etc., are disclosed in the present invention.

A quantum register can be read out using under-resolved emissions mapping (e.g., imaging). Regions of the quantum register are illuminated concurrently, one array site per region at a time, typically until all sites of each region have been illuminated. A photodetector system then detects for each region whether or not an EMR emission (e.g., due to fluorescence) has occurred in response to illumination of a respective site in that region. The result of the photo detections is a series of emissions maps, e.g., images. The number of emissions maps in the series corresponds to a number of sites per region, while the number of pixels in each image corresponds to a number of regions. A readout result can be based on a time-multiplexed combination of these emissions maps. The emissions maps are under-resolved since the resolution corresponds to the region size rather than the sizes of individual array sites.

Systems and methods for low power magnetic field generation for atomic sensors using electro-permanent magnets are provided. In one embodiment, a method for magnetic field generation for an atomic sensor comprises: laser cooling a sample of atoms in a chamber; and trapping the sample of atoms in a magneto-optical trap within the chamber by applying an atom trapping field across the sample of atoms using at least one pair of electro-permanent magnet units.

A system for three-dimensional (3D) optical trap printing (OTP) comprises a first particle susceptible to being cured by a light beam, a first light source to generate a trapping light beam to trap the particle, and a second light source to generate a curing light beam to cure the first particle. Using scanning and other optics, the trapping light beam may move the first particle to a desired printing location at which the curing light beam may cure the first particle, thereby adding the first particle to a printed structure. Using OTP, structures may be printed in any orientation, with or without support structures. Additionally, OTP allows for printing composite materials, high resolution color printing, printing of complex structures without sacrificial filler material, simultaneous printing of multiple particles, and combining particles at a print location.

Provided is a method and system for manipulating a particle by using an optical tweezer. The method includes accelerating the optical tweezer in which the particle is trapped, turning off the optical tweezer, and to catch the particle thrown by the optical tweezer that is turned off, turning on and decelerating the optical tweezer.

A three-dimensional magneto-optical trap (3D GMOT) configured to trap a cold-atom cloud is disclosed. The 3D GMOT includes a single input light beam having its direction along a first axis, an area along a second and third axis that are both normal to the first axis, and a substantially flat input light beam intensity profile extending across its area. The 3D GMOT may also include a circular, diffraction-grating surface positioned normal to the first axis and having closely adjacent grooves arranged concentrically around a gap formed in its center. The circular, diffraction-grating surface is configured to diffract first-order light beams that intersect within an intersection region that lies directly above the gap and suppresses reflections and diffractions of all other orders. The 3D GMOT may further include a quadrupole magnetic field with its magnitude being zero within the intersection region.

A system and method for controlling particles using projected light are provided. In some aspects, the method includes generating a beam of light using an optical source, and directing the beam of light to a beam filter comprising a first mask, a first lens, a second mask, and a second lens. The method also includes forming an optical pattern using the beam filter, and projecting the optical pattern on a plurality of particles to control their locations in space.

In an aspect, the present disclosure provides a method comprising providing a plurality of atoms. At least one atom of the plurality of atoms may have a different state than one or more other atoms of the plurality of atoms. The at least one atom may be excited to an excited state. The exciting may be performed using a non-site selective excitation beam over the plurality of atoms that only interacts with the at least one atom.

Furthermore, an atom trapping method for creating a two-dimensional arrangement of atoms and an atom trap apparatus, like an optical atomic clock, a quantum simulation and/or a quantum computing device are described.

The specification describes a method of reconfiguring particles in a grid of particle traps from an initial configuration to a target configuration, the grid of particle traps having target particle traps and surplus particle traps, the particles being movable along rows of the grid, or along columns of the grid, the rows being transversal to the columns.
