  4. 2. Quantum-Dot Heat Engines

    Author : Martin Josefsson; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quantum dot; heat engine; thermoelectric; quantum thermodynamics; quantum transport; Fysicumarkivet A:2020:Josefsson;

    Abstract : This thesis explores the possibilities of using quantum dots (QDs) in nanoscale energy har- vesters converting heat into electrical energy, i.e. heat engines. From a theory perspective, these possibilities have been investigated for almost two decades, and interest in them seem to continuously increase over time. READ MORE

  5. 3. Microwave Gaussian quantum metrology

    Author : Robert Jonsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum Fisher Information; Bosonic channel; Quantum Sensing; Gaussian; Quantum Radar;

    Abstract : With increasingly sensitive measurements being made possible by technological development, there arises situations where the effects of quantum mechanics have to be taken into account. While quantum mechanics tells us that there are fundamental limits of measurement sensitivity, it also gives us the tools to constructively push the same limits for experimental systems. READ MORE

  6. 4. Superconducting qubits - measurement, entanglement, and noise

    Author : Lars Tornberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum Electric Circuits; Open Quantum Systems; Quantum Optics; Quantum Computing; Superconducting Qubits; Quantum Measurement;

    Abstract : In the early 1980’s, it was suggested that a computer obeying the laws of quantum mechanics would be able to solve problems beyond the capabilities of a classical computer. The novel ways in which such a quantum computer works relies on the quantum properties of the quantum bits (qubits) used to store the information. READ MORE

  7. 5. For a Fistful of Qubits: Computational Quantum Chemistry on Near-Term Quantum Computers

    Author : Mårten Skogh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonadiabatic processes; quantum error mitigation; variational quantum algorithms; quantum computation; computational chemistry;

    Abstract : Quantum computing has been touted as a great new frontier of computation, pushing the limits of what we consider within reach of computation. While not all problems are expected to be efficiently solved by a quantum computer, quantum chemistry is among those where many have speculated on near-term quantum advantage. READ MORE
