For certain quantum architectures and algorithms, most of the required resources are consumed during the distillation of one-qubit magic states for use in performing Toffoli gates. I show that the overhead for magic-state distillation can be reduced by merging distillation with the implementation of Toffoli gates. The resulting routine distills eight one-qubit magic states directly to a Toffoli state, which can be used without further magic to perform a Toffoli gate. © 2013 American Physical Society.

With the fMAX of current generation InP transistors pushing above 1-THz and new transistor scaling in progress, the operational frequency of solid-state amplifiers is being pushed towards THz frequencies. In this paper we present out latest work towards demonstrating THz frequency amplifiers, including measured gain and noise performance of a 0.48 THz low noise amplifier using scaled InP transistors. Initial performance of next generation transistors is also presented, along with infrastructure necessary to package and operate solidstate amplifiers at THz frequencies. © 2010 IEEE.

A system for providing a scalable semantic mechanism for policy-driven assessment and action taking on dynamically changing data includes a policy context that is a collection of ontologies that capture policies of the enterprise in a semantic, declarative grammar, in a semantic database, a performance context that receives and stores sensor data output monitoring managed assets persisted in a time-series database, a workflow context that determines the workflow process necessary to manage the managed asset based on the governance policies and sensor data, implemented using a workflow engine that supports a declarative workflow language, a decision context that contains business rules encoded in a declarative grammar, implemented using a business rule engine and in which the business rules define conditions under which an asset is corrected, and an adjudication context that defines all associations between the four contexts that are necessary to monitor and manage the enterprise managed assets.

A plasma power limiter fabricated using wafer-level fabrication techniques with other circuit elements. The power limiter includes a signal substrate having a first side and a second side, an input signal line formed on the first side, a signal transmission line formed on the second side and an output signal line formed on the first side. The power limiter also includes a ground substrate having a first side and a second side, and being bonded to the signal substrate to form a sealed cavity including an ionizable gas therebetween. The ground substrate includes a ground metal layer formed on the second side. A signal propagating on the input signal line at a power level greater than a threshold power level generates a voltage potential across the cavity that ionizes the gas and generates a plasma discharge, and limits power of the output signal coupled to the output signal line.

A system and method for real-time detection of anomalies in database or application usage is disclosed. Embodiments provide a mechanism to detect anomalies in database or application usage, such as data exfiltration attempts, first by identifying correlations (e.g., patterns of normalcy) in events across different heterogeneous data streams (such as those associated with ordinary, authorized and benign database usage, workstation usage, user behavior or application usage) and second by identifying deviations/anomalies from these patterns of normalcy across data streams in real-time as data is being accessed. An alert is issued upon detection of an anomaly, wherein a type of alert is determined based on a characteristic of the detected anomaly.
