  1. 1. Generation and detection of entangled single-photon pairs

    Kandidat-uppsats, Uppsala universitet/FREIA

    Författare :Gabriella Tesfamichael Habtezion; [2024]
    Nyckelord :;

    Sammanfattning : Quantum information technology is an emerging field with important applications such as quantum cryptography and teleportation, quantum imaging and lithography. These applications make use of single photons and pairs of entangled photons. In this work, we experimentally generate and attempt to detect the entangled photons. LÄS MER

  3. 2. Active flow control of the turbulent boundary layer over a NACA4412 wing profile for skin friction drag reduction

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Giacomo Semprini Cesari; [2023]
    Nyckelord :Active flow control; drag reduction; numerical simulations; turbulent boundary layer; wings;

    Sammanfattning : In the context of building a framework for active flow control of turbulent boundary layers in wings, a set of large-eddy simulation (LES) are implemented in OpenFOAM. The flow around a NACA4412 wing profile is simulated at 5° angle of attack and Re_c = 400˙000. LÄS MER

  4. 3. RF Compressor (SLED) Phase-Modulation to Reduce Peak Fields in the MAX IV Linear Accelerator

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Joel Ekström; [2023]
    Nyckelord :Accelerator; MAX IV; LINAC; Phase-modulation; SLED; Pulse compression; Technology and Engineering;

    Sammanfattning : Modern particle accelerators need strong electric fields in order to produce high energy particles. Such high voltages are typically reached by injecting pulsed radio frequency power through several steps of amplification. At the end, pulse compression is used to further improve the energy gain at the cost of pulse-length. LÄS MER

  5. 4. Particle Simulation and Optimization of a Relativistic Magnetron for HPM Applications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Wilhelm Thunberg; [2022]
    Nyckelord :Relativistic Magnetron; FOI Magnetron; TE11; HPM; High Power Microwaves; Particle in cell; MAgic3d;

    Sammanfattning : A relativistic magnetron (RM) is a high-power microwave (HPM) source. The main objective of the RM is to generate directed electromagnetic pulses with high power, which can be used in e.g. HPM weapons and for electromagnetic compatibility testing. LÄS MER

  7. 5. Folding HP Proteins on a Quantum Annealer

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Författare :Lucas Knuthson; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Quantum annealing provides a promising avenue for obtaining good approximate solutions to difficult optimization problems. Protein folding represents one such problem. For testing novel algorithms and technologies, simplified lattice models are well suited, as they represent considerable computational challenges despite their simplicity. LÄS MER
