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: A BEC-station and a cloud-based server cooperate to provide Bose-Einstein condensates as a service (BECaaS). The BEC station serves as a system for implementing “recipes” for producing, manipulating, and/or using cold (<1 mK) a BEC, e.g., of 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 BEC station. The session manager controls (in some cases real-time) interactions between a user and a BEC station, some interactions allowing a user to select a recipe based on results returned earlier in the same session.

Abstract: An atomtronics station and a cloud-based server cooperate to provide Bose-Einstein condensates as a service (ATaaS). The atomtronics station serves as a system for implementing “recipes” for producing, manipulating, and/or using atomtronic devices based on cold atoms that are, in some respects, analogous to classical electronic devices based on electricity.

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 an atomtronics station. The session manager controls (in some cases, real-time) interactions between a user and an atomtronics station, some interactions allowing a user to select a recipe based on results returned earlier in the same session.

Abstract: A microwave sensor determines an electric-field strength of a microwave field populated by quantum particles in an ultra-high vacuum (UHV) cell. A probe laser beam and a coupling laser beam are directed into the UHV cell so that they are generally orthogonal to each other and intersect to define a “Rydberg” intersection, so-called as the quantum particles within the Rydberg intersection transition to a pair of Rydberg states. The frequency of the probe laser beam is swept so that a frequency spectrum of the probe laser beam can be captured. The frequency spectrum is analyzed to determine a frequency difference between Autler-Townes peaks. The electric-field strength of the microwave field within the Rydberg intersection is then determined based on this frequency difference.

Abstract: A quantum-mechanics station (?-station) and a cloud-based server cooperate to provide quantum mechanics as a service (?aaS) including real-time, exclusive, interactive sessions. The ?-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 ?-station. The session manager controls (e.g., in real-time) interactions between a user and a ?-station, some interactions allowing a user to select a recipe based on wavefunction characterizations returned earlier in the same session.

Abstract: A quantum sensor including a training agent and a target quantum system is described. The target quantum system includes quantum state carriers that are capable of being mutually entangled. The training agent includes a training quantum system. The target quantum system receives a control input. An output in response to the control input is obtained from the target quantum system. The training agent evaluates the output and determines a subsequent control input for the target quantum system.

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.

Abstract: A qubit array reparation system includes a reservoir of ultra-cold particle, a detector that determines whether or not qubit sites of a qubit array include respective qubit particles, and a transport system for transporting an ultra-cold particle to a first qubit array site that has been determined by the probe system to not include a qubit particle so that the ultra-cold particle can serve as a qubit particle for the first qubit array site. A qubit array reparation process includes maintaining a reservoir of ultra-cold particles, determining whether or not qubit-array sites contain respective qubit particles, each qubit particle having a respective superposition state, and, in response to a determination that a first qubit site does not contain a respective qubit particle, transporting an ultracold particle to the first qubit site to serve as a qubit particle contained by the first qubit site.

Abstract: A resonator for coherent oscillator matterwaves (COMW) includes a cavity bound by reflectors. The reflectors are fields of light blue-detuned with respect to an energy-level transition of the rubidium 87 (87Rb) atoms that constitute the COMW. One of the reflectors is partially transmissive to that COMW can enter and exit the resonator. The COMW resonator can be used to stabilize a COMW oscillator much as an optical resonator can stabilize a laser.

Abstract: A closed-loop coherent oscillator matterwave (COMW) system generates a COMW. Atoms tunnel into a COMW oscillator to populate the COMW generated and emitted by the oscillator. A detuned light-field-based COMW splitter divides the emitted COMW between an output COMW and a regulator COMW. A COMW resonator, including detuned light-field mirrors, receives the regulator COMW and returns a feedback COMW. A COMW sensor evaluates the intensity of the feedback COMW. A controller adjusts the oscillator based on the evaluation to optimize the COMW output of the system.

Abstract: An electromagnetic field detector including a vapor cell, an excitation system, and a frequency tuner is described. The vapor cell has a plurality of quantum particles therein. The excitation system excites the quantum particles to a first Rydberg state. The first Rydberg state has a transition to a second Rydberg state at a first frequency. The frequency tuner generates a tunable field in a portion of the vapor cell. The tunable field shifts the first Rydberg state and/or the second Rydberg state such that the transition to the second Rydberg state is at a second frequency different from the first frequency. The detection frequency range for the electromagnetic field detector is continuous and includes the first frequency and the second frequency.

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.
