Relativistic quantum information theory and quantum reference frames

摘要: This thesis is a compilation of research in relativistic quantum information theory, and reference frames. The the former category provides fundamental construction theory localised qubits curved spacetimes. For example, this concerns experiments on free-space photons electrons vicinity Earth. From field description that traverse classical trajectories spacetimes obtained, for massive spin-1/2 fermions. equations governing evolution two-dimensional state its absolute phase are determined. Quantum these then developed. Stern-Gerlach measurement formalism fermions also derived from theory. In latter research, process changing frames considered case where systems. As part process, it shown decoherence necessarily induced any system described relative to explored using examples involving orientation. Quantifying effect theoretical experiments, serves as first step developing relativity principle theories which all objects including quantum.
