    摘要: A 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 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 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.

    摘要: 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.

    摘要: An adaptive quantum signal processor (AQSP) includes a signal combiner, a physics station, a measurement system, a machine-learning engine and an output generator. The signal combiner combines incoming signals with control functions to yield recipe functions. For example, the recipe functions can be “shaking” functions used to change the wavefunctions of atoms entrained in an optical lattice. The recipe functions are applied to wavefunctions in initial wavefunction states causing the wavefunctions to transition to signal-impacted states. The measurement system measures the wavefunctions in their signal-impacted quantum states to yield wavefunction characterizations. The machine-learning engine updates control functions based on the wavefunction characterizations. The output generator outputs results based on the wavefunction characterizations and/or control function characterizations. In a matched-filter application, the outputs characterize (e.g., identify, classify, rate) the incoming signals.

    摘要: 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 an atom-chip cell which cools the cold particles to below 1 μK; these particles are stored in a reservoir within the atom-chip 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 atom-chip cell to prevent near-resonant light leaking from the MOTs from entering the atom-chip cell (and exciting the ultra-cold particles in the reservoir). The transporting from the MOTs to the atom-chip 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 atom-chip cell.

    摘要: 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.

    摘要: 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.

    摘要: A microwave sensor includes a cloud of particles, e.g., Rubidium 87 atoms. A probe laser beam transitions ground-state particles in its path to an excited state. A set of one or more coupling laser beams causes excited particles to transition to a first Rydberg state so that particles in the intersection of the laser beams are in a dark superposition which is transparent to the probe laser beam so that a frequency spectrum of the probe laser beam shows a transmission peak at the laser frequency. A microwave lens focuses a microwave vector (e.g., a microwave signal) within the intersection, causing particles in the first Rydberg state to transition to a second Rydberg state, splitting the transmission peak into a pair of peaks. The intensity of the microwave vector can be calculated based on the frequency difference between the pair of peaks. The direction of the microwave vector can be determined from the location of the laser-beam intersection.

    摘要: The present invention provides an matter-wave transistor in which the flow of particles (e.g., atoms and molecules) through the transistor is a result of resonant tunneling from a source well, through a gate well and into a drain well (as opposed to being a result of collisions, as in a classical atomtronic transistor). The transistor current of matter-wave particles can be controlled as a function of the breadth of resonant tunneling conditions of the gate well. For example, the resonant tunneling conditions of a gate well that does not include a dipole-oscillating Bose-Einstein condensate (DOBEC) can be broadened by including a DOBEC in the gate well. Similarly, the breadth of resonant tunneling conditions of the gate well can be changed by changing the particle population of a DOBEC in the gate well.

    摘要: 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.
