Geometrically robust linear optics from non-Abelian geometric phases
Julien Pinske, Stefan Scheel
We construct a unified operator framework for quantum holonomies generated from bosonic systems. For a system whose Hamiltonian is bilinear in the creation and annihilation operato…

Highly-Degenerate Photonic Waveguide Structures for Holonomic Computation
Julien Pinske, Lucas Teuber, Stefan Scheel
We investigate an all-out optical setup allowing for generation of non-Abelian geometric phases on its large degenerate eigenspaces. The proposal has the form of an M -pod system a…

Holonomic Gates in Pseudo-Hermitian Quantum Systems
Julien Pinske, Lucas Teuber, Stefan Scheel
The time-dependent pseudo-Hermitian formulation of quantum mechanics allows to study open system dynamics in analogy to Hermitian quantum systems. In this setting, we show that the…
