Non-Markovian interactions with pulses of quantum radiation
Julien Pinske, Stefan Scheel
The interaction of a traveling pulse of quantum light with a localized quantum system shows non-Markovian features when scattering takes place in a structured environment. Here, we…
Non-adiabatic holonomies as photonic quantum gates
Vera Neef, Julien Pinske, Tom A. W. Wolterink +4
One of the most promising nascent technologies, quantum computation faces a major challenge: The need for stable computational building blocks. We present the quantum-optical reali…
Particle-Number Threshold for Non-Abelian Geometric Phases
Julien Pinske, Vincent Burgtorf, Stefan Scheel
When a quantum state traverses a path, while being under the influence of a gauge potential, it acquires a geometric phase that is often more than just a scalar quantity. The varie…
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…
Symmetry-protected non-Abelian geometric phases in optical waveguides with nonorthogonal modes
Julien Pinske, Stefan Scheel
The generation of non-Abelian geometric phases from a system of evanescently coupled waveguides is extended towards the framework of nonorthogonal coupled-mode theory. Here, we stu…
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…
