  1. 1. Quantum error correction

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Jonas Almlöf; KTH.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum error correction; dissipative channel; decoherence; fidelity; mutual information;

    Sammanfattning : This thesis intends to familiarise the reader with quantum error correction, and also show some relations to the well known concept of information - and the lesser known quantum information. Quantum information describes how information can be carried by quantum states, and how interaction with other systems give rise to a full set of quantum phenomena, many of which have no correspondence in classical information theory.

  2. 2. Quantum error correction

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Jonas Almlöf; KTH.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : Quantum error correction is the art of protecting quantum states from the detrimental influence from the environment. To master this art, one must understand how the system interacts with the environment and gives rise to a full set of quantum phenomena, many of which have no correspondence in classical information theory.

  3. 3. Superconducting qubits - measurement, entanglement, and noise

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Lars Tornberg; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum Electric Circuits; Open Quantum Systems; Quantum Optics; Quantum Computing; Superconducting Qubits; Quantum Measurement;

    Sammanfattning : In the early 1980’s, it was suggested that a computer obeying the laws of quantum mechanics would be able to solve problems beyond the capabilities of a classical computer. The novel ways in which such a quantum computer works relies on the quantum properties of the quantum bits (qubits) used to store the information. LÄS MER

  4. 4. Measurement Back-Action and Photon Detection in Microwave Quantum Optics

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Anton Frisk Kockum; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Parity Measurement; Quantum Measurement; Quantum Optics; Quantum Stochastic Calculus; Circuit QED; Photodetection; Transmon; Dephasing;

    Sammanfattning : In quantum optics, the interaction between atoms and photons is studied. In recent years, microwave quantum optics with superconducting circuits has emerged as an important tool for fundamental quantum optics experiments, and also as a promising way for implementing quantum computation.

  5. 5. Aspects of Fixed-point Implementation of Multiuser Detctors in WCDMA

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Hongxia Zhao; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Wideband code-division multiple-access (WCDMA) has been selected as the radio technique standard for the 3G mobile communication systems. However, it is well known that the conventional single-user detector, which is commonly used in CDMA systems, suffers from multiple-access interference (MAI). LÄS MER
