Abstract: A matter-wave gyro with counter-propagating traps uses three-dimensional lattices formed of interference fringes from three pairs of interfering laser beams. Particles, such as neutral atoms, ion, or molecules are cooled to a ground state near absolute zero. The resulting ultra-cold particles are loaded into the lattices. The laser beams used to form the lattices are driven according to functions that cause the lattices to counter-propagate about a closed path (Sagnac loop) N times, where a desired tradeoff between spatial resolution and temporal resolution can be achieved by choosing an appropriate integer value of N. The lattices can be extinguished so that the particles can be imaged to identify an interference pattern. A shift in the interference pattern relative to an interference pattern that would occur with zero angular momentum can be used to measure angular momentum.

Abstract: A probe laser beam causes molecules to transition from a ground state to an excited state. A control laser beam causes molecules in the excited state to transition to a laser-induced Rydberg state. Microwave lenses convert a microwave wavefront into respective microwave beams. The microwave beams are counter-propagated through molecules so as to create a microwave interference pattern of alternating maxima and minima. The microwave interference pattern is imposed on the probe beam as a probe transmission pattern. The propagation direction of the microwave wavefront can be determined from the translational position of the probe transmission pattern; the intensity of the microwave wavefront can be determined by the intensity difference between the minima and maxima of the probe transmission pattern.

Abstract: A 3D microwave sensor includes a cloud of particles, e.g., rubidium 87 atoms. A laser system produces: a first probe beam directed through the particle cloud along a first path; a second probe beam directed through the particle cloud along a second path that intersects the first path to define a Rydberg intersection; a first coupling beam that counterpropagates with respect to the first probe beam along the first path; and a second coupling beam that counterpropagates with respect to the second probe beam along the second path. A spectrum analyzer characterizes the microwave field strength at the Rydberg intersection. The laser beams can be steered to move the Rydberg intersection within the particle cloud to compile a microwave field strength distribution in the particle cloud.

Abstract: An accelerometer/gravitometer based on coherent oscillatory matterwaves (COMW). The accelerometer includes a pair of COMW generator systems, each with an oscillator and a respective resonator to stabilize the oscillator output. One of the resonators can be aligned with acceleration, while the other is transverse to the acceleration. The COMW generator outputs can be compared to derive a measurement of acceleration.

Abstract: A shaken-lattice station and a cloud-based server cooperate to provide shaken lattices as a service (SLaaS). The shaken-lattice station serves as a system for implementing “recipes” for creating and using shaking functions to be applied to light used to trap quantum particles. The cloud-based server acts as an interface between the shaken-lattice station (or stations) and authorized users of account holders. To this end the server hosts an account manager and a session manager. The account manager manages accounts and associated account-based and user-specific permissions that define what actions any given authorized user for an account may perform with respect to a shaken-lattice station. The session manager controls (e.g., in real-time) interactions between a user and a shaken-lattice station, some interactions allowing a user to select a recipe based on results returned earlier in the same session.

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 quantum-mechanics station (Ψ-station) and a cloud-based server cooperate to provide quantum mechanics as a service (ΨaaS) including real-time, exclusive, interactive sessions. The Ψ-station serves as a system for implementing “recipes” for producing, manipulating, and/or using quantum-state carriers, e.g., rubidium 87 atoms. The cloud-based server acts as an interface between the station (or stations) and authorized users of account holders. To this end, the server hosts an account manager and a session manager. The account manager manages accounts and associated account-based and user-specific permissions that define what actions any given authorized user for an account may perform with respect to a Ψ-station. The session manager controls (e.g., in real-time) interactions between a user and a Ψ-station, some interactions allowing a user to select a recipe based on wavefunction characterizations returned earlier in the same session.
