Dissipative and stochastic geometric phase of a qubit within a canonical Langevin framework

Pedro Bargueño, Salvador Miret-Artés

Dissipative and stochastic effects in the geometric phase of a qubit are taken into account using a geometrical description of the corresponding open-system dynamics within a canonical Langevin framework based on a Caldeira-Leggett-like Hamiltonian. By extending the Hopf fibration ${S}^{3}\ensuremath{\rightarrow}{S}^{2}$ to include such effects, the exact geometric phase for a dissipative qubit is obtained, whereas numerical calculations are used to include finite-temperature effects on it.

Control of the Geometric Phase in Two Open Qubit–Cavity Systems Linked by a Waveguide

Abdel‐Baset A. Mohamed, Ibtisam A. H. Masmali

We explore the geometric phase in a system of two non-interacting qubits embedded in two separated open cavities linked via an optical fiber and leaking photons to the external environment. The dynamical behavior of the generated geometric phase is investigated under the physical parameter effects of the coupling constants of both the qubit-cavity and the fiber-cavity interactions, the resonance/off-resonance qubit-field interactions, and the cavity dissipations. It is found that these the physical parameters lead to generating, disappearing and controlling the number and the shape (instantaneous/rectangular) of the geometric phase oscillations.
