Abstract: Atom-scale particles, e.g., neutral and charged atoms and molecules, are pre-cooled, e.g., using magneto-optical traps (MOTs), to below 100 μK to yield cold particles. The cold particles are transported to a sensor cell which cools the cold particles to below 1 μK using an optical trap; these particles are stored in a reservoir within an optical trap within the sensor cell so that they are readily available to replenish a sensor population of particles in quantum superposition. A baffle is disposed between the MOTs and the sensor cell to prevent near-resonant light leaking from the MOTs from entering the sensor cell (and exciting the ultra-cold particles in the reservoir). The transporting from the MOTs to the sensor cell is effected by moving optical fringes of optical lattices and guiding the cold particles attached to the fringes along a meandering path through the baffle and into the sensor cell.

Abstract: A fully reciprocal atomic interferometric gyroscope is provided. The fully reciprocal atomic interferometric gyroscope includes an atomic chamber, a plurality of lasers, a controller and measurement sensor. The atomic chamber is used to hold an atom cloud. The plurality of lasers are selectively positioned to selectively direct laser beams into the atomic chamber. The controller is configured to control the plurality lasers to initially cool the atom cloud to a point where at least one optical lattice can be formed that is used to move wave function halves of atoms of the atom cloud along split wave function paths that form an interferometer cycle. The measurement sensor is configured to conduct a phase readout of a wave function upon the completion of at least one interferometer cycle around the split wave function paths.

Abstract: A flexible electronic device includes a flexible electronic circuit and a flexible microfluidic sensor homogeneously integrated into the flexible circuit. The flexible sensor includes a flexible microfluidic structure, a first material, a second material, and an electrode arrangement. At least one of the first and second materials is a fluid. The structure defines at least one microfluidic chamber. The first and second materials are disposed in the chamber. The second material has a physical property and an electrical property different from the first material. The electrode arrangement includes at least one pair of electrodes spaced apart from each other with at least a portion of the at least one chamber located functionally directly therebetween such that at least one electronic property measured across the pair is based on a relationship between the second material and the electrode pair. The relationship is based on a physical condition of the microfluidic structure.

Abstract: A system for controlling a phase measurement in an atom interferometer comprising one or more lasers, a processor, and a memory. The one or more lasers are for providing interrogating beams. A first cloud of atoms and a second cloud of atoms traverse an interrogating region of the atom interferometer in substantially opposite directions. The interrogating beams interact substantially simultaneously with both atoms in the first cloud and atoms in the second cloud. The first cloud of atoms and the second cloud of atoms interact with each of the interrogating beams in a different order. The processor is configured to determine a phase adjustment offset of at least one interrogating beam based at least in part on one or more past interactions of one or more interrogating beams with either the first cloud of atoms or the second cloud of atoms.

Abstract: One embodiment of the invention includes an atom beam gyroscope system. The system includes an atom beam system that generates an atom beam comprising alkali metal atoms along a length of a detection region orthogonal to a sensitive axis. The system also includes a detection system comprising a detection laser and photodetector. The detection laser can generate an optical detection beam that illuminates the detection region to pump the alkali metal atoms. The photodetector can measure an optical absorption of the optical detection beam by the alkali metal atoms in the atom beam and to generate an intensity signal associated with the measured optical absorption. The system further includes a gyroscope sensor configured to calculate rotation of the atom beam gyroscope system about the sensitive axis based on a magnitude of the intensity signal due to a Doppler-shift in energy of the alkali metal atoms in the atom beam.
