  1. 1. Probabilistic Exact Inversion of 2-qubit Bipartite Unitary Operations using Local Operations and Classical Communication

    University essay from KTH/Fysik

    Author : Ludvig Lindström; [2024]
    Keywords : Resource Theory; Resource theory of entanglement; Quantum Information Theory; Quantum Computing; Distributed Quantum Computing; Higher-order quantum transformation; Quantum Algorithms; Quantum Physics; Resursteori; Resursteori för Kvantsammanflätning; Kvantinformationsteori; Kvantdatorer; Distribuerade kvantdatorer; Högre ordningens kvanttransformationer; Kvantalgoritmer; Kvantfysik;

    Abstract : A distributed quantum computer holds the potential to emulate a larger quantumcomputer by being partitioned it into smaller modules where local operations (LO)can be applied, and classical communication (CC) can be utilized between thesemodules. Finding algorithms under LOCC restrictions is crucial for leveraging thecapabilities of distributed quantum computing, This thesis explores probabilisticexact LOCC supermaps, that maps 2-qubit bipartite unitary operations to its inver-sion and complex conjugation.

  3. 2. Superconducting gates for InP HEMTs

    University essay from KTH/Tillämpad fysik

    Author : Sebastian Alveteg; [2023]
    Keywords : Cryogenic electronics; HEMT; Superconductors; Applied Physics; Kryogenisk elektronik; HEMT; Supraledare; Tillämpad fysik;

    Abstract : The thesis examines the prospects of using the superconductor NbN as the gatemetal for an InP HEMT. A HEMT or High Electron Mobility Transistor is aheterostructure transistor engineered to reach very high electron mobility. InPHEMTs are used as cryogenic Low Noise Amplifiers (LNAs), which have increasedin demand as quantum computing is scaling up. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

    Abstract : 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. READ MORE

  5. 4. Simulating the Impact of Noise on Quantum Walk Algorithm

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Wilhelm Öberg; Sam Shahriari; [2023]
    Keywords : ;

    Abstract : Quantum computing has recently shown promise for improving the efficiency of some classical algorithms. However, quantum computing suffers from issues in reliability due to the fundamental problem of quantum mechanics called decoherence. READ MORE

  6. 5. Cost and efficiency comparison of Quantum Key Distribution schemes

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Erik Lidbjörk; Rasmus Söderström Nylander; [2023]
    Keywords : ;

    Abstract : 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. READ MORE
