Appl. No.:

13/284536

International Classification:

G01N 21/65

US Classification:

356301

Abstract:

A process for entangling quantum states of respective quantum systems measures electromagnetic radiation emitted from a first system and from a second system. The two systems are exposed to excitation radiation having a probability per time of producing a photon, and an interference element is coupled to receive photons from the first and second systems. The process further includes measuring a time during which the first and second systems were exposed to the excitation radiation before a photon is detected on either output channel of the interference element and applying an electromagnetic pulse that causes a relative phase shift of a portion of a quantum state of the first and second systems. Parameters of the electromagnetic pulse are selected based on measurements of the electromagnetic radiation from the first and second systems and the time measured.

International Classification:

H01S 3/05

US Classification:

359346

Abstract:

A quantum device includes a resonator and a tuning structure. The tuning structure is made a material such as a chalcogenide and is positioned to interact with the electromagnetic radiation in the resonator so that a resonant mode of the first resonator depends on a characteristic of the tuning structure. The resonator is optically coupled so that a transition between quantum states associated with a defect produces electromagnetic radiation in the resonator. The characteristic of the tuning structure is adjustable after fabrication of the resonator and the tuning structure.

International Classification:

A61B 5/00
A61B 5/05

Abstract:

Systems and methods are described that enable sensing of magnetic fields within skin tissue. Specifically, a system includes one or more microneedles that include a high magnetic permeability material. The system also includes a magnetic sensor communicatively coupled to the microneedle and configured to detect a magnetic field proximate to the microneedle. The system also includes a controller configured to receive information indicative of a magnetic field proximate to a portion of the microneedle. The controller is further configured to determine a presence of at least one magnetic nanoparticle proximate to the portion of the microneedle based on the received information. Alternatively, other embodiments include a microneedle that includes a nanodiamond material configured to detect a local magnetic field. Such embodiments also include a light source configured to cause the nanodiamond material to emit characteristic emission light that may indicate at least a magnitude of the magnetic field.

International Classification:

A61B 5/00
A61B 5/1455

Abstract:

Optical measurement of physiological parameters with wearable devices often includes measuring signals in the presence of significant noise sources. These noise sources include, but are not limited to, noise associated with: variable optical coupling to skin or tissue, variations in tissue optical properties with time due to changes in humidity, temperature, hydration, variations in tissue optical properties between individuals, variable coupling of ambient light sources into detectors, and instrument and detector noise, including electrical noise, radio frequency or magnetic interference, or noise caused by mechanical movement of the detector or its components. The present disclosure includes devices and methods configured to produce representations of the raw data in which noise, broadly defined, is separated from the data of interest. The disclosed devices and methods may include subtracting or calibrating out these noise sources and other spurious fluctuations in wearable devices with optical sensors.

Abstract:

An engineered particle for detecting analytes in an environment includes an electromagnetic receiver that is configured to preferentially receive electromagnetic radiation of a specified polarization relative to the orientation of the electromagnetic receiver. The engineered particle additionally includes an energy emitter coupled to the electromagnetic receiver such that a portion of electromagnetic energy received by the electromagnetic receiver is transferred to and emitted by the energy emitter. The engineered particles are functionalized to selectively interact with an analyte. The engineered particle can additionally be configured to align with a directed energy field in the environment. The selective reception of electromagnetic radiation of a specified polarization and/or alignment with a directed energy field can enable orientation tracking of individual engineered particles, imaging in high-noise environments, or other applications. A method for detecting properties of the analyte of interest by interacting with the engineered particle is also provided.

Abstract:

Methods are provided to identify spatially and spectrally multiplexed probes in a biological environment. Such probes are identified by the ordering and color of fluorophores of the probes. The devices and methods provided facilitate determination of the locations and colors of such fluorophores, such that a probe can be identified. In some embodiments, probes are identified by applying light from a target environment to a spatial light modulator that can be used to control the direction and magnitude of chromatic dispersion of the detected light; multiple images of the target, corresponding to multiple different spatial light modulator settings, can be deconvolved and used to determine the colors and locations of fluorophores. In some embodiments, light from a region of the target can be simultaneously imaged spatially and spectrally. Correlations between the spatial and spectral images over time can be used to determine the color of fluorophores in the target.
