Abstract

An output-amplifier-based reciprocal quantum logic (RQL) bias-level sensor is used to measure and/or calibrate bias parameters of AC and/or DC bias signals provided to RQL circuitry. The bias signals can include an output amplifier output bias current. The bias-level sensor includes a stack of DC SQUIDs that are supplied their inputs from outputs of respective Josephson transmission lines (JTLs) to which the SQUIDs are transformer-coupled. Staging relative strengths of the bias taps of the JTLs, or the critical currents of the Josephson junctions in the DC SQUIDs, allows an output voltage signal of the bias-level sensor to be indicative of whether a provided bias value is an improvement or optimization of the bias value when varied over a range. The outputs of two such bias-level sensors driven by I and Q clocks can be compared to adjust AC bias amplitudes of the clocks. Relative clock phase can be similarly adjusted.

Other metal traces on the other surface of the substrate also provide high frequency transmission lines and reference ground. An enclosure made using semiconductor manufacturing technology is mounted to the substrate and has conductive interior recesses defined by extending walls that are connected to the reference ground. The recesses surround the respective components and provide electromagnetic shielding. The dimensional precision in the location and smoothness of the walls and recesses due to the semiconductor manufacturing technology provides repeatable unit-to-unit RF characteristics of the RF module. One way of mounting the enclosure to the substrate uses a plurality of metal bonding bumps extending outwardly from the walls to engage reference ground metal traces on the substrate. Applied pressure deforms the bonding bumps to form a metal-to-metal bond.

Abstract

Methods for fabricating high-temperature composite structures (e.g., structures comprising carbon-carbon composite materials or ceramic composite matrix (CMC) materials and configured for use at temperature at or exceeding about 2000° F. (1093° C.)) include forming precursor structures by additive manufacturing (“AM”) (e.g., “3D printing”) with a filament drawn from a spool. The precursor structures are exposed to high temperatures to pyrolyze a precursor matric material of the initial 3D printed structure. A liquid resin is used to impregnate the pyrolyzed structure, to densify the structure into a near-net final shape. Use of expensive and time-consuming molds and post-processing machining may be avoided. Large, unitary, integrally formed parts conducive for use in high-temperature environments may be formed using the methods of the disclosure.

Abstract

An atomic clock system includes a waveguide cavity that is sealed and comprises a gas enclosed therein. The waveguide cavity has a length that is an integer multiple of approximately one half-wavelength of a resonant frequency of the gas between two states. An oscillator system generates an RF signal through the waveguide cavity. The RF signal has a signal frequency that is approximately equal to the resonant frequency of the gas. A detection system measures a characteristic of the RF signal through the waveguide cavity to detect a maximum transition between the two states of the gas and to provide a feedback signal to the oscillator system to lock the signal frequency of the RF signal to the resonant frequency of the gas based on detecting the maximum transition. The detection system provides a frequency reference output signal based on the signal frequency of the RF signal.

Abstract

Pulse-generator-based reciprocal quantum logic (RQL) bias-level sensors are fabricated on an RQL integrated circuit (IC) to sample AC or DC bias values provided to operational RQL circuitry on the RQL IC. The bias-level sensors include pulse generators having strengthened or weakened bias taps (transformer couplings to RQL AC clock resonators or DC bias lines) as compared to bias taps of Josephson transmission lines in the operational RQL circuitry, or Josephson junctions (JJs) with larger or smaller critical currents as compared to JJs in the operational RQL circuitry. Pulse generators with weakened bias taps or larger JJs can have lower limits of their operational ranges placed near an optimal bias point at the centroid of the operating region of the operational RQL circuitry. The bias-level sensors can be staged by relative strength to indicate whether a provided bias value is an improvement when varied over a range.

Abstract

Pulse-generator-based reciprocal quantum logic (RQL) bias-level sensors are fabricated on an RQL integrated circuit (IC) to sample AC or DC bias values provided to operational RQL circuitry on the RQL IC. The bias-level sensors include pulse generators having strengthened or weakened bias taps (transformer couplings to RQL AC clock resonators or DC bias lines) as compared to bias taps of Josephson transmission lines in the operational RQL circuitry, or Josephson junctions (JJs) with larger or smaller critical currents as compared to JJs in the operational RQL circuitry. Pulse generators with weakened bias taps or larger JJs can have lower limits of their operational ranges placed near an optimal bias point at the centroid of the operating region of the operational RQL circuitry. The bias-level sensors can be staged by relative strength to indicate whether a provided bias value is an improvement when varied over a range.

Abstract

An output-amplifier-based reciprocal quantum logic (RQL) bias-level sensor is used to measure and/or calibrate bias parameters of AC and/or DC bias signals provided to RQL circuitry. The bias signals can include an output amplifier output bias current. The bias-level sensor includes a stack of DC SQUIDs that are supplied their inputs from outputs of respective Josephson transmission lines (JTLs) to which the SQUIDs are transformer-coupled. Staging relative strengths of the bias taps of the JTLs, or the critical currents of the Josephson junctions in the DC SQUIDs, allows an output voltage signal of the bias-level sensor to be indicative of whether a provided bias value is an improvement or optimization of the bias value when varied over a range. The outputs of two such bias-level sensors driven by I and Q clocks can be compared to adjust AC bias amplitudes of the clocks. Relative clock phase can be similarly adjusted.

Abstract

The disclosed invention provides system and method for multi-path mesh network communications. The network system utilizes multiple communication paths and linearly encoded and disassembled packets through mathematical coding techniques that respectively travel the communication paths. The system includes an encoder, a transmitter, a decoder and a receiver. The encoder receives data from an external source and linearly encodes and simultaneously disassembles the data to generate copackets. None of the individual copackets contain decodable information of the data. The transmitter is coupled to the multiple communication paths and respectively transmits the copackets through different communication paths. The receiver receives the copackets transmitted through the communication paths. The decoder decodes available copackets and reassembles the data from the available copackets if a number of the available copackets are no less than a mathematically calculated number. The reassembled data has the complete information of the data originally transmitted.

Abstract

Shift register elements of a phase-mode bit-addressable sensing register sample varied AC or DC bias values provided to operational RQL circuitry on the RQL IC via clock resonators or DC bias lines. The shift register can be constructed of phase-mode D flip-flops and JTLs as data and clock lines. A method of using the sensing register includes shifting in a data bit pattern while a bias parameter (e.g., AC amplitude, DC value, or phase) is set to a nominal value; stopping the logical clock that controls the shifting of values through the sensing register, varying the bias parameter value, inputting one assertion SFQ pulse or reciprocal pulse pair into the logical clock, restoring the bias parameter to the nominal value, restarting the logical clock to shift out an output data bit pattern, and observing the output data bit pattern to determine the effect of the bias parameter value change.

Abstract

A key updater for a first party operating on a network generates a mutually distilled key for communication between the first party and a second party. The key updater determines a set of verifying parties operating on the network needed to authenticate the mutually distilled key, wherein each verifying party of the set of verifying parties operates on the network. The key updater iteratively executes a key equivalency test for each verifying party in the set of verifying parties to determine a nonce sum until the key equivalency test has been executed for each of the verifying parties in the set of verifying parties or until it is determined that at least one node on the network has been compromised. The key updater generates a final key for communication between the first party and the second party based on the nonce sum and the mutually distilled key.

Abstract

The present disclosure relates to an evaluation of system-of-systems (SoS) architectures for cyber vulnerabilities. In an example, architecture description data and component description data for an SoS can be received. Architecture definition file (ADF) data can be generated based on the architecture and component description data. A model of a target SoS architecture for the SoS can be generated based on the ADF data. The target SoS architecture for the SoS can be evaluated to identify potential cyber-attack vectors with respect to the target SoS architecture, and a probabilistic analysis of the potential cyber-attack vectors can be executed to compute a probability for each cyber-attack vector indicative of a likelihood that a respective cyber-attack results in a mission failure by the SoS based on the target SoS architecture. Display data can be generated for visualization on an output device that includes each identified potential cyber-attack vector and associated computed probability.

Abstract

In an example, a component analyzer can compute a respective part score for each part of the platform based on a part property table, and a respective connection score for each connection of the platform based on a connection property table. The component analyzer can provide the respective part and connection scores as score data to an architecture modeling engine to compute a probability model based on the score data and an architecture model. The probability model can include a part probability value and a connection probability value, and the architecture model can characterize a target architecture of the platform. A survivability analysis engine can evaluate the probability model and the architecture model to determine a likelihood that one or more potential cyber-attacks on the platform based on the target architecture are successful or unsuccessful in compromising at least one part of the platform.
