  1. 1. Representation of Quantum Algorithms with Symbolic Language and Simulation on Classical Computer

    Författare :Peter Nyman; Andrei khrennikov; Paul Fischer; Växjö universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deutsch-Josza algorithm; Grover s algorithm; Quantum computing; Quantum error-correcting; Shor s algorithm; Simon s algorithm; Simulation of quantum algorithms; Deutsch-Josza algoritm; Grovers algoritm; Kvantdatorer; kvantmekanisk felrättande kod; Shors algoritm; Simons algoritm; Simulering av kvantdatorer; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

    Sammanfattning : Utvecklandet av kvantdatorn är ett ytterst lovande projekt som kombinerar teoretisk och experimental kvantfysik, matematik, teori om kvantinformation och datalogi. Under första steget i utvecklandet av kvantdatorn låg huvudintresset på att skapa några algoritmer med framtida tillämpningar, klargöra grundläggande frågor och utveckla en experimentell teknologi för en leksakskvantdator som verkar på några kvantbitar.

  3. 2. A Resource for Quantum Computation

    Författare :Niklas Johansson; Jan-Åke Larsson; Peter Jonsson; Christian Calude; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis we address the question, what is the resource, or property, that enables the advantage of quantum computers? The theory of quantum computers dates back to the eighties, so one would think there already is an answer to this question. There are several proposed solutions, but to this date, there is no consensus on an answer. LÄS MER

  4. 3. Semiconductor Quantum Optics at Telecom Wavelengths

    Författare :Katharina Zeuner; Val Zwiller; Klaus D. Jöns; Stephan Reitzenstein; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optik och fotonik; Optics and Photonics;

    Sammanfattning : Quantum technologies are an expanding field in physics and engineering concerning the development of protocols and devices that enable augmented or novel applications based on quantum mechanics. This includes amongst others quantum computation and quantum communication. LÄS MER

  5. 4. Coherent Interactions in Rare-Earth-Ion-Doped Crystals for Applications in Quantum Information Science

    Författare :Mattias Nilsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum optics; relaxation; magnetic resonance; supraconductors; magnetic and optical properties; electrical; Condensed matter:electronic structure; Atom- och molekylärfysik; optical information processing; coherence in solids; Atomic and molecular physics; rare-earth-ion-doped crystals; magnetisk resonans; spektroskopi; supraledare; magnetiska och optiska ; egenskaper elektriska; Kondenserade materiens egenskaper:elektronstruktur; spectroscopy; quantum information;

    Sammanfattning : This thesis describes investigations of the use of cryogenically cooled rare-earth-ion-doped crystals for quantum information processing and quantum optics. Several aspects of the coherent interaction between light and rare-earth ions in solids are addressed. Quantum information science has given physicists new views of quantum mechanics. LÄS MER

  7. 5. Correlation spectroscopy with epitaxial quantum dots : Single-photons alone in the dark

    Författare :Lucas Schweickert; Val Zwiller; Klaus D. Jöns; Richard J. Warburton; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum dots; single--photons; indistinguishability; entanglement; Optik och fotonik; Optics and Photonics;

    Sammanfattning : The advent of quantum computation promises exciting advances, not only in fields like medicine and metrology, but many industries that rely on parameter-heavy calculations or simulation of molecular interaction. At the same time Shor's algorithm for quantum computers presents a threat to current asymmetric encryption protocols used in everyday communication. LÄS MER
