Abstract: Conventional efforts for estimating the geographic location (geolocation) of devices associated with particular Internet Protocol (IP) addresses typically yield woefully inaccurate results. In many cases, the estimated IP geolocations are on the wrong continent. Embodiments of the present technology include techniques for identifying and improving incorrect estimates based on latency measurements, Domain Name Server (DNS) information, and routing information. For example, latency measurements from multiple collectors can be used to rate the plausibility of an IP geolocation estimate and, in certain cases, to increase the accuracy of the IP geolocation estimate. DNS and routing information can be used to corroborate the estimated IP geolocation. The resulting more accurate IP geolocation estimate can be used to route Internet traffic more efficiently, to enforce rules for routing sensitive information, and to simplify troubleshooting.

Abstract: Security guards at big facilities, such as airports, monitor multiple screens that display images from individual surveillance cameras dispersed throughout the facility. If a guard zooms with a particular camera, he will lose image resolution, along with perspective on the surrounding area. Embodiments of the inventive Imaging System for Immersive Surveillance (ISIS) solve these problems by combining multiple cameras in one device. When properly mounted, example ISIS systems offer 360-degree, 100-megapixel views on a single screen. (Other resolutions may also be employed.) Image-stitching software merges multiple video feeds into one scene. The system also allows operators to tag and follow targets, and can monitor restricted areas and sound an alert when intruders breach them.

Abstract: Radio-frequency identification (RFID) systems use readers to query and locate passive RFID tags in stores, warehouses, and other environments. A signal from the reader powers up the tag, which modulates and backscatters the signal toward the reader. Unfortunately, the maximum permitted RF signal power, self-interference at the reader, tag sensitivity, and channel loss limit the range at which readers can detect and locate tags. Using multiple readers simultaneously circumvents these limits. When used together, each reader transmits a signal to a tag in turn, and all of the readers listen for each of the tag's responses. The readers that are not transmitting do not experience self-interference and so can detect responses at lower power levels (longer ranges). Because the readers are at different locations, they measure different angles of arrival (AOAs) for each response. These simultaneous measurements can be used to locate each tag faster and with higher fidelity.

Abstract: A radio-frequency identification (RFID) tag reader interrogates RFID tags and detects their replies. These replies may propagate along direct or line-of-sight paths from the tags to the reader. They may also propagate along indirect or non-light-of-sight paths from the tags to the reader, e.g., by reflecting off nearby objects to the reader. As a result, the reader receives many copies of each tag's reply, with each copy arriving at a delay and angle corresponding to the path that it followed from the tag to the reader. The aggregate or combination of the detected replies is called a multipath profile or signature. Each tag/reader pair produces its own multipath profile. Moving objects near the reader and tag can change that multipath signature by introducing or removing reflections along a given path between the reader and tag. These changes can be used to determine that an object has moved, even if that object does not have an RFID tag.

Abstract: A hybrid quantum system performs high-fidelity quantum state transduction between a superconducting (SC) microwave qubit and the ground state spin system of a solid-state artificial atom. This transduction is mediated via an acoustic bus connected by piezoelectric transducers to the SC microwave qubit. For SC circuit qubits and diamond silicon vacancy centers in an optimized phononic cavity, the system can achieve quantum state transduction with fidelity exceeding 99% at a MHz-scale bandwidth. By combining the complementary strengths of SC circuit quantum computing and artificial atoms, the hybrid quantum system provides high-fidelity qubit gates with long-lived quantum memory, high-fidelity measurement, large qubit number, reconfigurable qubit connectivity, and high-fidelity state and gate teleportation through optical quantum networks.

Abstract: Industrial quality control is challenging for artificial neural networks (ANNs) and deep neural networks (DNNs) because of the nature of the processed data: there is an abundance of consistent data representing good products, but little data representing bad products. In quality control, the task is changed from conventional DNN task of "recognize what I learned best" to "recognize what I have never seen before." Lifelong DNN (L-DNN) technology is a hybrid semi-supervised neural architecture that combines the ability of DNNs to be trained, with high precision, on known classes, while being sensitive to any number of unknown classes or class variations. When used for industrial inspection, L-DNN exploits its ability to learn with little and highly unbalanced data. L- DNN's real-time learning capability takes advantage of rare cases of poor-quality products that L- DNN encounters after deployment. L-DNN can be applied to industrial inspections and manufacturing quality control.

Abstract: Optical read-out of a cryogenic device (such as a superconducting logic or detector element) can be performed with a forward-biased optical modulator that is directly coupled to the cryogenic device without any intervening electrical amplifier. Forward-biasing at cryogenic temperatures enables very high modulation efficiency (1,000-10,000 pm/V) of the optical modulator, and allows for optical modulation with millivolt driving signals and microwatt power dissipation in the cryogenic environment. Modulated optical signals can be coupled out of the cryostat via an optical fiber, reducing the thermal load on the cryostat. Using optical fiber instead of electrical wires can increase the communication bandwidth between the cryogenic environment and room- temperature environment to bandwidth densities as high as Tbps/mm2 using wavelength division multiplexing. Sensitive optical signals having higher robustness to noise and crosstalk, because of their immunity to electromagnetic interference, can be carried by the optical fiber.

Abstract: Systems based on atom and atom-like quantum emitters are promising platforms for quantum sensing, computing, and communications. State-of-the-art lasers and optical microscopy enable high-fidelity quantum control of the atomic quantum bits (qubits). Here, we introduce methods and systems to holographically implement large-scale quantum circuits that individually address atomic quantum nodes for various applications. These methods enable implementation of quantum circuits over large 2D and 3D arrays of atomic qubits at rates of thousands to millions of quantum circuit layers per second. The quantum circuit layers are encoded in multiplexed holograms displayed on a slow SLM and retrieved by fast interrogation to produce spatial distributions that operate on the qubit array. This technology can also be used for optically addressing objects such as biological cells and on-chip photonic components for optical tweezers, opto-genetics, optical computing, and optical neural networks.

Abstract: Optical interconnects can offer higher bandwidth, lower power, lower cost, and higher latency than electrical interconnects alone. The optical interconnect system enables both optical and electrical interconnection, leverages existing fabrication processes to facilitate package-level integration, and delivers high alignment tolerance and low coupling losses. The optical interconnect system provides connections between a photonics integrated chip (PIC) and a chip carrier and between the chip carrier and external circuitry. The system provides a single flip chip interconnection between external circuitry and a chip carrier using a ball grid array (BGA) infrastructure. The system uses graded index (GRIN) lenses and cross-taper waveguide couplers to optically couple components, delivers coupling losses of less than 0.5 dB with an alignment tolerance of ± 1 μm, and accommodates a 2.5x higher bandwidth density.

Abstract: An analog computing system with coupled non-linear oscillators can solve complex combinatorial optimization problems using the weighted Ising model. The system is composed of a fully-connected LC oscillator network with low-cost electronic components and compatible with traditional integrated circuit technologies. Each LC oscillator, or node, in the network can be coupled to each other node in the array with a multiply and accumulate crossbar array or optical interconnects. When implemented with four nodes, the system performs with single-run ground state accuracies of 98% on randomized MAX-CUT problem sets with binary weights and 84% with five-bit weight resolutions. The four-node system can obtain solutions within five oscillator cycles with a time-to-solution that scales directly with oscillator frequency. A scaling analysis suggests that larger coupled oscillator networks may be used to solve computationally intensive problems faster and more efficiently than conventional algorithms.
