Abstract: A device for modulating an amplitude of a light beam, comprising a coherent light source configured to generate a phase-modulated beam having a plurality of frequency components; and a dispersive optical element. The dispersive optical element has a group delay dispersion and is configured to receive the phase-modulated beam, to introduce an optical phase shift to each of the plurality of the frequency components, so that the values of the optical phase shift vary non-linearly with frequency according to the group delay dispersion, and to recombine the plurality of frequency components, thereby generating an amplitude-modulated beam.

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 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: An identification of a first area of an IC design surrounding a failure component is received; and, in response, a smaller portion of the first area is selected. The smaller portion also surrounds the failure component, is smaller than the first area, and contains less circuit components than the first area. The smaller portion is matched to other areas of the IC design to identify potentially undesirable patterns of the IC design that are the same size as the first area. Additionally, the potentially undesirable patterns are grouped into pattern categories, the pattern categories are matched to known good pattern categories, and the known good patterns are removed from the potentially undesirable patterns to leave potential failure patterns. The potential failure patterns of the IC design are then output.
