  • hybrid quantum Information Processing a way for large scale optical quantum Information Processing
    European Quantum Electronics Conference, 2017
    Co-Authors: Akira Furusawa
    Abstract:

    We are working on hybrid quantum Information Processing, which combines two methodologies of quantum Information Processing — qubit and continuous variable (CV) [1]. More precisely, we encode logical qubits by using CV methodology and utilize CV quantum processors for the realization of a fault-tolerant large-scale universal optical quantum computer. The advantage of this methodology is that we can have both high-fidelity nature of qubits and determinisity of CV quantum processors. In other words, we can enjoy both particle- and wave-nature of quantum mechanics. Towards this goal we performed various things, which include quantum error correction with nine-party CV entanglement [2], teleportation of Schrodinger's cat state [3], adaptive homodyne measurement with phase-squeezed states [4], deterministic teleportation of time-bin qubits [5], creation of ultra-large-scale CV cluster states [6], generation and measurement of CV entanglement on a chip [7], and synchronization of photons with cavity-based quantum memories [8].

  • optical hybrid quantum Information Processing
    arXiv: Quantum Physics, 2016
    Co-Authors: Shuntaro Takeda, Akira Furusawa
    Abstract:

    Historically, two complementary approaches to optical quantum Information Processing have been pursued: qubits and continuous-variables, each exploiting either particle or wave nature of light. However, both approaches have pros and cons. In recent years, there has been a significant progress in combining both approaches with a view to realizing hybrid protocols that overcome the current limitations. In this chapter, we first review the development of the two approaches with a special focus on quantum teleportation and its applications. We then introduce our recent research progress in realizing quantum teleportation by a hybrid scheme, and mention its future applications to universal and fault-tolerant quantum Information Processing.

  • Quantum Teleportation and Entanglement: A Hybrid Approach to Optical Quantum Information Processing - Hybrid quantum Information Processing
    2014
    Co-Authors: Akira Furusawa
    Abstract:

    I will briefly explain the definition and advantage of hybrid quantum Information Processing, which is hybridization of qubit and continuous-variable technologies. The final goal would be realization of universal gate sets both for qubit and continuous-variable quantum Information Processing with the hybrid technologies. For that purpose, qubit teleportation with a continuousvariable teleporter is one of the most important ingredients.

  • Quantum teleportation for continuous variables and related quantum Information Processing
    Physics Reports, 2007
    Co-Authors: Akira Furusawa, Nobuyuki Takei
    Abstract:

    Quantum teleportation is one of the most important subjects in quantum Information science. This is because quantum teleportation can be regarded as not only quantum Information transfer but also a building block for universal quantum Information Processing. Furthermore, deterministic quantum Information Processing is very important for efficient Processing and it can be realized with continuous-variable quantum Information Processing. In this review, quantum teleportation for continuous variables and related quantum Information Processing are reviewed from these points of view.

  • Information-Processing bias in social phobia.
    Clinical Psychology Review, 2004
    Co-Authors: Colette R. Hirsch, David M. Clark
    Abstract:

    Social phobia is a persistent disorder that is unlikely to be maintained by avoidance alone. One reason for the enduring nature of social phobia may be the way individuals with the disorder process social Information. It is important for those involved in social phobia to have an understanding of Information-Processing biases, because it has the potential to guide psychological interventions. In this review of social phobia, probability and cost estimates of social situations are examined, interpretive biases are evaluated and findings relating to memory and negative imagery are also reviewed. The clinical implications of social-phobia-related Information-Processing biases are discussed and possible avenues for future research are outlined.

  • Information Processing in social phobia
    Biological Psychiatry, 2002
    Co-Authors: David M. Clark, Freda Mcmanus
    Abstract:

    Cognitive theories suggest that Information Processing biases play a central role in the development and maintenance of emotional disorders. The present article reviews recent studies of Information Processing biases in social phobia and considers the significance of the findings for understanding the persistence of the condition. Taken together, the studies suggest that social phobia is characterized by biases in the following: interpretation of external social events; detection of negative responses from other people; the balance of attention between external and self-Processing; the use of internal Information to make inferences about how one appears to others; recall of negative Information about one's perceived, observable self; and by a variety of problematic anticipatory and post-event types of Processing. If such biases play a role in maintaining social anxiety, experimental manipulation of the biases should modulate anxiety responses. Several recent studies have confirmed this prediction, but further research is required. Methodological limitations of existing Information Processing studies are highlighted. Finally, possible neurobiological correlates are discussed and suggestions are made for future attempts to link neurobiology and cognitive psychology.
