In particular, I consider an oscillating magnetic field whose frequency is varied and brought into resonance with a spin qubit set in a static magnetic field. I evaluate the fidelity of this manipulation in a simple case numerically. I explain the algorithm used in the quantum jump method and using this algorithm I model a manipulated spin-qubit system reaching thermal equilibrium with its environment. I find the probability for a state transition caused by this manipulation to be proportional to the square of the ratio of the drive field and static field strengths C_0/B, when the ratio is of the order 0.01.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2021-11-16T05:54:29Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-11-16T05:54:29Z (GMT).
