Tomography of a spin qubit in a double quantum dot
Maki Takahashi, Stephen D. Bartlett, Andrew C. Doherty
We investigate a range of methods to perform tomography in a solid-state qubit device, for which a priori initialization and measurement of the qubit is restricted to a single basi…
WKB analysis of relativistic Stern-Gerlach measurements
Matthew C. Palmer, Maki Takahashi, Hans F. Westman
Spin is an important quantum degree of freedom in relativistic quantum information theory. This paper provides a first-principles derivation of the observable corresponding to a St…
Localized qubits in curved spacetimes
Matthew C. Palmer, Maki Takahashi, Hans F. Westman
We provide a systematic and self-contained exposition of the subject of localized qubits in curved spacetimes. This research was motivated by a simple experimental question: if we…
