1. Quantum Interference : Improved Accuracy and Quantum Limits
Sammanfattning : .... LÄS MER
2. Quantum-Dot Heat Engines
Sammanfattning : 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. LÄS MER
3. Microwave Gaussian quantum metrology
Sammanfattning : 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. LÄS MER
4. Superconducting qubits - measurement, entanglement, and noise
Sammanfattning : 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. LÄS MER
5. For a Fistful of Qubits: Computational Quantum Chemistry on Near-Term Quantum Computers
Sammanfattning : 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. LÄS MER
