  1. 1. Gossiping electrons : Strong decoherence from screening

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Felix Langueville; [2022]
    Nyckelord :Quantum mechanics; Decoherence; Quantum decoherence; Screening; Decoherence from screening; quantum entanglement; entangled electrons; Kvantfysik; Dekoherens; Kvantmekanisk sammanflätning; skärmning; Dekoherens från skärmning;

    Sammanfattning : In a strongly correlated material the localized electrons, typically the electrons in the 3d-orbitals, become entangled with each other through the Coulomb interaction. However, these electrons also interact with more mobile (itinerant) electrons in the s- and p-orbitals. LÄS MER

  3. 2. Quantum Entanglement and Superconducting Qubits

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Wai Ho Tang; [2014]
    Nyckelord :Quantum; Entanglement; Superconducting; Qubit; SQUID; Quantum gate;

    Sammanfattning : Conventional computing based on classical technologies is approaching its limits. Therefore scientists are starting to consider the applications of quantum mechanics as a means for constructing more powerful computers. After proposing theoretical methods, many experimental setups have been designed to achieve quantum computing in reality. LÄS MER

  4. 3. Ordering of Entangled States for Different Entanglement Measures

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Författare :Jennie Sköld; [2014]
    Nyckelord :Quantum entanglement; entanglement measures; pure state; mixed state; density matrix; von Neumann entropy; entanglement cost; entanglement distillation; entanglement of formation; relative entropy of entanglement;

    Sammanfattning : Quantum entanglement is a phenomenon which has shown great potential use in modern technical implementations, but there is still much development needed in the field. One major problem is how to measure the amount of entanglement present in a given entangled state. LÄS MER
