  • Patent number: 11605475
    Abstract: A technique is disclosed for electro-optically inducing a force to fabricated samples and/or devices with laser light. The technique uses the interaction of the oscillating electric field of the laser beam in opposition with the electric field produced by an appropriate electric charge carrier to achieve a net repulsive (or attractive) force on the component holding the electric charge. In one embodiment, force is achieved when the field near the charge carrier is modulated at a subharmonic of the electric field oscillation frequency of the laser and the relative phases of the light field and electric charge carrier field are controlled to provide optimal repulsion/attraction. The effect is scalable by applying the technique to an array of charge carrier fields sequentially as well as using higher power lasers and higher carrier field voltages.

  • Patent number: 11334812
    Abstract: A cold-quanta station and a cloud-based server cooperate to provide cold quanta as a service (CQaaS). The cold-quanta station serves as a system for implementing “recipes” for producing, manipulating, and/or using cold (<1 mK) monatomic or polyatomic molecules, e.g., cold 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 quantum-mechanics station. The session manager controls (in some cases real-time) interactions between a user and a quantum-mechanics station, some interactions allowing a user to select a recipe based on results returned earlier in the same session.

  • Patent number: 11309684
    Abstract: The invention relates to coherent single photon sources that provide photons with a high degree of indistinguishability. It is a disadvantage of single photon sources based on QDs in nanophotonic structures that, even at low temperatures, acoustic vibrations interact with the QDs to reduce the coherence of the emitted spectrum. The invention uses mechanical clamping of the nanostructure to damp vibrations leading to a weaker QD—phonon coupling and a higher degree of indistinguishability between successively emitted photons. The clamp is mechanically connected to the length of the photonic nanostructure and has a stiffness and a size sufficient to suppress low frequency vibrations (??10 GHz) in a combined structure of the clamp and the nanostructure.

  • Patent number: 11257605
    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 ?K to yield cold particles. The cold particles are transported to a sensor cell which cools the cold particles to below 1 ?K 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.

  • Patent number: 11156460
    Abstract: The present disclosure relates to Superfluid QUantum Interference Devices (SQUIDs) that measure phase differences existing in quasi-particles or matter-wave systems, and the related techniques for their use at room-temperatures. These Bose-Einstein Condensation interferometry techniques include quantum scale metrology devices such as quasi-particle based linear accelerometers, gyroscopes, and Inertial Measurement Units that incorporate such interferometers. In the presence of additive white Gaussian noise, estimates are made for the Bias Instability, Angle Random Walk, and Velocity Random Walk of the device for purposes of quantum inertial sensing. Moreover, this disclosure relates to SQUIDs based on charged quasi-particles that can, in turn, be used to construct quantum computing elements such as quantum transistors, and quasi-particle circuits at room-temperatures. These quasi-particle circuits can be used to build analogs of electronic circuit elements, and offer an alternative to traditional electronics.
