  1. 6. On quantum systems and the measurement problem

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Nicolas Boulle; [2023]
    Nyckelord :Quantum physics; the measurement problem; quantum information; Hilbert spaces; physical systems; unitary; collapse; Euler angles parametrization; Copenhagen interpretation; many- world; measure;

    Sammanfattning : We focus on the Tensor Product Structure (TPS) of the Hilbert space and the fact that a choice in the TPS has an impact on the representation of the studied quantum system. We define the measurement problem in quantum mechanics and present some theories about quantum mechanics, each of them highlighting a different approach to quantum measurements. LÄS MER

  3. 7. The Effect of Noise Levels on the Performance of Shor’s Algorithm

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Niklas Höstedt; Tobias Ljunggren; [2023]
    Nyckelord :Bachelor’s thesis; Quantum Computing; Shor’s algorithm; Noise; Cryptography; Qiskit; Kandidatexamensarbete; Kvantdatorer; Shors algorithm; Brus; Kryptografi; Qiskit;

    Sammanfattning : Advanced enough quantum computers promise to revolutionise fields such as cryptography, drug discovery and simulations of complex systems. Quantum computers are built on qubits which are fragile and susceptible to error-inducing interference, which is called noise. LÄS MER

  4. 8. Quantum Reinforcement Learning for Sensor-Assisted Robot Navigation Tasks

    Master-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Joyce Cobussen; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Quantum computing has advanced rapidly throughout the past decade, both from a hardware and software point of view. A variety of algorithms have been developed that are suitable for the current generation of quantum devices, which are referred to as noisy intermediate-scale quantum devices. LÄS MER

  5. 9. Revival structure of the residual entanglement in a three-qubit system

    Kandidat-uppsats,

    Författare :Carl Agelii; Rasmus Andersson; William Bakke Lindblom; [2023]
    Nyckelord :qubit; tripartite entanglement; residual entanglement; antisymmetric exchange; Quantum Heisenberg model;

    Sammanfattning : The quantum mechanical phenomenon of entanglement plays a key role in areas such as quantum computing and quantum information. Entangled half spin particles, often called qubits, are used to realize quantum based logic which means that studying systems of qubits and their properties is of vital importance to the development of the fields.

  7. 10. THE COUPLING OF A DOUBLE QUANTUM DOT TO MICROWAVE PHOTONS

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Mohamed Abrash; [2023]
    Nyckelord :Quantum computing; Qubit; Double quantum dot DQD ; Microwave resonator; Quantum integrated circuits; Sweet spots; Hybrid quantum circuits.; Physics and Astronomy;

    Sammanfattning : In this study, we derive a mathematical description of a double quantum dot (DQD) embedded in a microwave resonator starting from classical electrostatics. DQDs are a promising platform for building quantum computers and have important applications in quantum sensing and the study of light-matter interactions. LÄS MER
