  1. 1. Cost and efficiency comparison of Quantum Key Distribution schemes

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

    Författare :Erik Lidbjörk; Rasmus Söderström Nylander; [2023]
    Nyckelord :;

    Sammanfattning : The development of quantum computing exposes critical vulnerabilities in classical encryption systems. However, quantum computing also enables new methods of secure communication. Quantum key distribution (QKD) is one class of such methods. LÄS MER

  3. 2. Quantum Algorithms for Feature Selection and Compressed Feature Representation of Data

    Master-uppsats, KTH/Fysik

    Författare :William Laius Lundgren; [2023]
    Nyckelord :Feature selection; autoencoders; quantum machine learning; quantum circuits; quantum annealing; Funktionsval; datakompression; kvantmaskininlärning; kvantalgoritmer; kvantkretsar;

    Sammanfattning : Quantum computing has emerged as a new field that may have the potential to revolutionize the landscape of information processing and computational power, although physically constructing quantum hardware has proven difficult,and quantum computers in the current Noisy Intermediate Scale Quantum (NISQ) era are error prone and limited in the number of qubits they contain.A sub-field within quantum algorithms research which holds potential for the NISQ era, and which has seen increasing activity in recent years, is quantum machine learning, where researchers apply approaches from classical machine learning to quantum computing algorithms and explore the interplay between the two.

    Sammanfattning : Quantum computing is an emerging field with potential applications in machine learning. This research project aimed to compare the performance of a quantum kernel to that of a classical kernel in machine learning binary classification tasks. LÄS MER

  5. 4. The Effect of Noise on Grover's Algorithm when Searching with Multiple Marked Items

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