Description logics based languages have became the standard representation scheme for ontologies. They formalize the domain knowledge using interrelated concepts, contained in terminologies. The manual definition of terminologies is an expensive and error prone task, therefore automatic learning methods are a necessity. In this paper we lay the foundations of a multiple concept learning method that uses virtual concepts to aid the learning process, yielding more compact and readable terminologies. In this paper, we define virtual concepts and how they can be implemented in the current concept learning methods. We show through experiments how the method stacks up against other multiple concept learning methods.

Individuals who are visually impaired encounter a number of challenges when attempting to orientate their own position or the position of others in relation to them within an unfamiliar indoor environment. To design an orientation assistive technology, it is crucial to understand the factors that reduce the user's sense of orientation. In this work, we discuss the disorientation factors that resulted from three user studies, which were conducted to formulate the basic requirements for an orientation assistive technology to assist visually impaired individuals in unfamiliar indoor areas. Using the feedback we elicited from one survey and two interview studies, we shed light on the factors that reduce the user's sense of orientation in unfamiliar buildings such as noise and traffic levels.

Nonzero Classical Discord

Quantum discord is the quantitative difference between two alternative expressions for bipartite mutual information, given respectively in terms of two distinct definitions for the conditional entropy. By constructing a stochastic model of shared states, classical discord can be similarly defined, quantifying the presence of some stochasticity in the measurement process. Therefore, discord can generally be understood as a quantification of the system’s state disturbance due to local measurements, be it quantum or classical. We establish an operational meaning of classical discord in the context of state merging with noisy measurement and thereby show the quantum-classical separation in terms of a negative conditional entropy.

Controlling Quantum Devices with Nonlinear Hardware

High-fidelity coherent control of quantum systems is critical to building quantum devices and quantum computers. We provide a general optimal control framework for designing control sequences that account for hardware control distortions while maintaining robustness to environmental noise. We demonstrate the utility of our algorithm by presenting examples of robust quantum gates optimized in the presence of nonlinear distortions. We show that nonlinear classical controllers do not necessarily incur additional computational cost to pulse-optimization, enabling more powerful quantum devices.

Entanglement over global distances via quantum repeaters with satellite links

We study entanglement creation over global distances based on a quantum repeater architecture that uses low-Earth-orbit satellites equipped with entangled photon sources, as well as ground stations equipped with quantum nondemolition detectors and quantum memories. We show that this approach allows entanglement creation at viable rates over distances that are inaccessible via direct transmission through optical fibers or even from very distant satellites.

Security loophole in free-space quantum key distribution due to spatial-mode detector-efficiency mismatch

引用

Physical Review A 2015年第6期91卷 062301-062301页

作者： Shihan Sajeed Poompong Chaiwongkhot Jean-Philippe Bourgoin Thomas Jennewein Norbert Lütkenhaus Vadim Makarov Institute for Quantum Computing University of Waterloo Waterloo Ontario N2L 3G1 Canada Department of Electrical and Computer Engineering University of Waterloo Waterloo Ontario N2L 3G1 Canada Department of Physics and Astronomy University of Waterloo Waterloo Ontario N2L 3G1 Canada Quantum Information Science Program Canadian Institute for Advanced Research Toronto Ontario M5G 1Z8 Canada

In free-space quantum key distribution (QKD), the sensitivity of the receiver's detector channels may depend differently on the spatial mode of incoming photons. Consequently, an attacker can control the spatial mode to break security. We experimentally investigate a standard polarization QKD receiver and identify sources of efficiency mismatch in its optical scheme. We model a practical intercept-and-resend attack and show that it would break security in most situations. We show experimentally that adding an appropriately chosen spatial filter at the receiver's entrance may be an effective countermeasure.

Technology to automatically synthesize linguistically accurate and natural-looking animations of American Sign Language (ASL) from an easy-to-update script would make it easier to add ASL content to websites and media, thereby increasing information accessibility for many people who are deaf. We are investigating the synthesis of ASL facial expressions, which are grammatically required and essential to the meaning of sentences. To support this research, we have enhanced a virtual human character with face controls following the MPEG-4 Facial Action Parameter standard. In a user-study, we determined that these controls were sufficient for conveying understandable animations of facial expressions.
