  1. 21. Generating quantum entangled photons

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Stephan Nieto; Daniel Sanaee; [2021]
    Nyckelord :;

    Sammanfattning : In this project a laser setup was constructed, quantum entangled photons were generated and two different methods were used to show said entanglement. The entangled photons were generated through a process called spontaneous parametric down conversion (SPDC). LÄS MER

  3. 22. Recent Progress on the Black Hole Information Paradox

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Eivind Hilmen Jørstad; [2021]
    Nyckelord :Black Holes; Hawking Radiation; Entanglement Entropy; Black Hole Information Paradox; Dilaton Gravity; Quasiparticles; Physics and Astronomy;

    Sammanfattning : The black hole information paradox is of central importance in the study of quantum gravity. The paradox states that quantum fields surrounding a black hole behave in ways that run into conflict with the unitarity of quantum mechanical time evolution. LÄS MER

  4. 23. Towards Machine Translation with Quantum Computers

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Irene Vicente Nieto; [2021]
    Nyckelord :;

    Sammanfattning : This work explores the possibilities to use quantum computers and quantum based language models for machine translation. Precise translation requires vast expertise and knowledge of various languages, thus machine translationis still far from superseding humans. LÄS MER

  5. 24. Signatures of topological phases in an open Kitaev chain

    Master-uppsats, KTH/Fysik

    Författare :Natalia Ermakova; [2021]
    Nyckelord :Kitaev chain; open quantum systems; Lindblad equation; topological quantum matter;

    Sammanfattning : Some physical systems exhibit topological properties in the form of topological invariants— features of the system that remain constant unless the system undergoessignificant changes i.e. changes that require closing the energy gap of the Hamiltonian.This work studies one example of a system with topological properties — a Kitaevchain.

  7. 25. Vilse, sårbar och bristfällig : Problematiserade subjekt i åtta samtida bilderböcker

    Master-uppsats, Umeå universitet/Institutionen för kultur- och medievetenskaper

    Författare :Sarah Nordgren; [2021]
    Nyckelord :Picture books; Subject; Subject formation; Materiality; Picture book theory; Diffraction; Compromise; Vulnerability; Bilderböcker; Subjekt; Subjektformation; Materialitet; Bilderboksteori; Diffraktion; Kompromiss; Sårbarhet;

    Sammanfattning : The purpose of this essay is to examine and problematize subject formation in relation to the materiality of picture books. A total of eight contemporary picture books are analyzed: Naturen by Emma AdBåge, Jag blir en bubbla som blir ett monster som blir ett barn by Malin Axelsson and Klara Persson, Gittan och gråvargarna by Pija Lindenbaum, I skogen and Olli och Mo by Eva Lindström, En egen flock by Maria Nilsson Thore, Om jag fötts till groda by Annika Sandelin and Karoliina Pertamo and Det var en gång en räv som sprang i mörkret by Anna-Clara and Thomas Tidholm.
