Geometric Phase in Twisted Topological Complementary Pair [PDF]

Advanced Science, 2023
Geometric phase enabled by spin‐orbit coupling has attracted enormous interest in optics over the past few decades. However, it is only applicable to circularly‐polarized light and encounters substantial challenges when applied to wave fields lacking the

Decoherence of geometric phase gates [PDF]

, 2001
We consider the effects of certain forms of decoherence applied to both adiabatic and non-adiabatic geometric phase quantum gates. For a single qubit we illustrate path-dependent sensitivity to anisotropic noise and for two qubits we quantify the loss of

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

Entropy, 2020
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.

Geometric phase for degenerate states of spin-1 and spin-1/2 pair [PDF]

Open Physics, 2007
The geometric phase of a bi-particle model is discussed. For different initial states, especially when the initial state is pure or mixed, the geometric phase will show different properties.

Quadrature Squeezing and Geometric-Phase Oscillations in Nano-Optics [PDF]

Nanomaterials, 2020
The geometric phase, as well as the familiar dynamical phase, occurs in the evolution of a squeezed state in nano-optics as an extra phase. The outcome of the geometric phase in that state is somewhat intricate: its time behavior exhibits a combination ...

Geometric Phase in Entangled Systems: A Single-Neutron Interferometer Experiment [PDF]

, 2009
The influence of the geometric phase on a Bell measurement, as proposed by Bertlmann et al. in [Phys. Rev. A 69, 032112 (2004)], and expressed by the Clauser-Horne-Shimony-Holt (CHSH) inequality, has been observed for a spin-path entangled neutron state ...

Geometric phase in Taub-NUT spacetime

European Physical Journal C: Particles and Fields, 2023
Constructing the Hamiltonian in the $$\eta $$ η -representation, we explore the geometric phase in the Taub-NUT spacetime, which is spherically symmetric and stationary.
