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: 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.

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.

IPC: G01R29/08
Abstract: 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.

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 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.
