Sense+compute (S+C) quantum-state carriers (QSCs), e.g., rubidium atoms, can be used provide more scalable quantum sensor systems. Multiple S+C QSCs can capture sensor data. The sensor data can then be transformed in the quantum domain according to a quantum tomographic protocol. The transformed data can be measured to provide a respective classical domain measurement. The sensing, transformation, and measurement can be repeated to provide a set of measurements (corresponding to different transformations) that can be combined according to the quantum tomography protocol to generate a model of the original quantum state. Estimation error associated with the model can be scaled down at a rate corresponding more closely to increases in the number N of QSCs than √{square root over (N)}, even in the presence of noise.

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.

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.

Closed-loop generation of coherent oscillatory matterwaves

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.

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.

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.

Wideband tunable rydberg microwave detector

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.

Quantum mechanics as a service

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.

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.

Bose-Einstein condensates as a service

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 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.

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.

Shaken lattice as a service

Atom-scale particles, e.g., neutral and charged atoms and molecules, are pre-cooled, e.g., using magneto-optical traps (MOTs), to below 100 &#x3bc;K to yield cold particles. The cold particles are transported to a sensor cell which cools the cold particles to below 1 &#x3bc;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.

Quantum sensor replenishment

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.

Qubit array reparation

A growing system and/or plant support structure may include one or more feet supporting at least one or more uprights, on which a plurality of plants and/or grow boards for growing plants may be positioned. A nutrient delivery system may be positioned between opposing uprights to provide nutrient supply to a root zone of plants, which nutrient delivery system may be positioned adjacent each opposing upright in an interior chamber of the plant support structure. A light system may be positioned between two adjacent plant support structures such that it simultaneously provides light to the exterior surface of the two plant support structures. A collapsible light may be positioned adjacent plants and plant support structures for improved access to the plants or plant support structures while allowing variable and controllable light distribution beneficial to control of adjacent plants and plant structures.
