Order-invariant two-photon quantum correlations in PT-symmetric interferometers
Tom A. W. Wolterink, Matthias Heinrich, Stefan Scheel +1
Multiphoton correlations in linear photonic quantum networks are governed by matrix permanents. Yet, surprisingly few systematic properties of these crucial algebraic objects are k…
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…
A Passive -Symmetric Floquet-Coupler
Lucas Teuber, Florian Morawetz, Stefan Scheel
Based on a Liouville-space formulation of open systems, we present a solution to the quantum master equation of two coupled optical waveguides with varying loss. The periodic modul…
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…
Solving the quantum master equation of coupled harmonic oscillators with Lie algebra methods
Lucas Teuber, Stefan Scheel
Based on a Liouville-space formulation of open systems, we present two methods to solve the quantum dynamics of coupled harmonic oscillators experiencing Markovian loss. Starting p…
