Abstract: An optical cavity array includes a plurality of mirrors that form an optical cavity, a first lens system located within the optical cavity, and a second lens system located within the optical cavity. The first lens system has a first output facing a first mirror of the plurality of mirrors and a second output facing a second mirror of the plurality of mirrors. The second lens system has a second input facing the first input and a second output facing the second mirror. The first and second lens systems are configured such that the optical cavity supports longitudinal modes that are transversely non-degenerate, forming spatially separated waists that lie along a focal plane that is axially located between the first and second inputs. When the longitudinal modes are excited, the waists may be used as an array of optical dipole traps.

Abstract: An optical cavity includes a plurality of mirrors that reflect light along a closed path. First and second mirrors of the plurality of mirrors define an optical axis therebetween. The optical cavity includes first and second lenses located between the first and second mirrors along the optical axis. A mode of the optical cavity has a waist located between the first and second intracavity lenses. Small values of the waist (e.g., <10 microns) produce large cooperativities that relax requirements for the cavity finesse (i.e., reflectivity of the mirrors). The mirrors may be retroreflecting to create a Fabry-Perot cavity. Alternatively, the first and second mirrors may define one segment of a ring cavity. The optical cavity may be used to trap, read, entangle, and drive nonlinear emitters (e.g., atoms, color centers, quantum dots) located near the waist.

Abstract: A nonlinear parametric device includes a planar substrate and a millimeter-wave resonator formed from superconductive material deposited on the planar substrate. When the resonator is cooled below a critical temperature, it exhibits nonlinear kinetic inductance that may be used to implement millimeter-wave nonlinear frequency generation and parametric amplification. Millimeter waves may be coupled into, and out of, the nonlinear parametric device with hollow rectangular electromagnetic waveguides. Niobium nitride is an excellent superconductive material for kinetic inductance due to its high intrinsic sheet inductance, a critical temperature that is higher than many other superconductive materials, and relatively low loss at millimeter-wave frequencies.

Abstract: A millimeter-wave resonator is produced by drilling a plurality of holes into a piece of metal. Each hole forms an evanescent tube having a lowest cutoff frequency. The holes spatially intersect to form a seamless three-dimensional cavity whose fundamental cavity mode has a resonant frequency that is less than the cutoff frequencies of all the evanescent tubes. Below cutoff, the fundamental cavity mode does not couple to the waveguide modes, and therefore has a high internal Q. Millimeter waves can be coupled into any of the tubes to excite an evanescent mode that couples to the fundamental cavity mode. The tubes also provide spatial and optical access for transporting atoms into the cavity, where they can be trapped while spatially overlapping the fundamental cavity mode. The piece of metal may be superconducting, allowing the resonator to be used in a cryogenic environment for quantum computing and information processing.

Abstract: The erasing of data stored in a nonvolatile memory is performed using multiple partial erase operations. Each partial erase operation has a time duration that is shorter than the minimum time duration of an erase operation that is needed to reliably erase the data stored in the storage location. However, the sum of the time durations of the multiple partial erase operations is sufficient to reliably erase the data in the storage location. In one example, during a partial erase operation, a voltage is applied to a memory storage transistor to remove some, but not necessarily all, of the charge stored on a charge storage layer of the transistor. Following multiple partial erase operations, sufficient charge is removed from the charge storage layer to ensure reliable data erasure.
