Experimental observation of hyperbolic spacetime dynamics
Jonas Himmel, Coraline Bacq, Krishna Chand Maurya +11
Understanding quantum dynamics in curved spacetime is a central challenge at the intersection of quantum mechanics and gravity. Anti-de-Sitter (AdS) spacetime plays a pivotal role…
Path integral quantization of the electromagnetic field in nonlinear dielectric materials
Arman Kashef, Oscar Perearnau Herrero, Alexander Szameit +2
We construct a quantum theory of light in nonlinear dielectric media with dispersion and absorption. We employ a mesoscopic model for the light-matter interaction that include a fo…
Optical Tautochrone and Squeezing Dynamics in Nonuniform Lattices
Ioannis Kiorpelidis, Matthias Heinrich, Alexander Szameit +2
We present exact analogies between the tautochrone problem of classical mechanics and the squeezed states of quantum optics to optical lattices. Both phenomena emerge in the same p…
Observation of Joule-Thomson photon-gas expansion
Marco S. Kirsch, Georgios G. Pyrialakos, Richard Altenkirch +9
In recent years, a self-consistent optical thermodynamic framework has emerged that offers a systematic methodology to understand, harness and exploit the complex collective dynami…
Non-Exponential Decay in Finite Photonic Waveguide Arrays
Florian H. Huber, Benedikt Braumandl, Johannes Knörzer +5
Open quantum-system dynamics can follow exponential decay, non-exponential relaxation, or oscillatory dynamics, depending on the system-environment coupling. We study a lattice wit…
Engineering Non-Hermitian Quantum Evolution Using a Hermitian Bath Environment
Mahmoud A. Selim, Max Ehrhardt, Yuqiang Ding +9
Engineering quantum bath networks through non-Hermitian subsystem Hamiltonians has recently emerged as a promising strategy for qubit cooling, state stabilization, and fault-tolera…
Drive-induced Non-local Interactions and Topological Bulk Transport of Extended Doublons
Julius Beck, Matthias Heinrich, Marcus J. Meschede +6
The existence of boundary states and their protection against symmetry-preserving perturbations are a hallmark feature of topological systems. While this concept originally emerged…
Pairing particles into holonomies
Vera Neef, Matthias Heinrich, Tom A. W. Wolterink +1
Holonomies are of great interest to quantum computation and simulation. The geometrical nature of these entities offers increased stability to quantum gates. Furthermore, symmetrie…
Selective Filtering of Photonic Quantum Entanglement via Anti-Parity-Time Symmetry
Mahmoud A. Selim, Max Ehrhardt, Yuqiang Ding +8
Entanglement is a key resource for quantum computing, sensing, and communication, however it is highly susceptible to decoherence. To address this, quantum optics has explored filt…
State Transfer in Latent-Symmetric Networks
Jonas Himmel, Max Ehrhardt, Matthias Heinrich +5
The transport of quantum states is a crucial aspect of information processing systems, facilitating operations such as quantum key distribution and inter-component communication wi…
Eigenmodes of latent-symmetric quantum photonic networks
Jonas Himmel, Max Ehrhardt, Matthias Heinrich +3
We investigate the impact of latent symmetries on the dynamics of photonic systems and their eigenmodes. Residing solely within the eigenspectral domain, latent symmetries are not…
Crossing exceptional points in non-Hermitian quantum systems
Friederike U. J. Klauck, Matthias Heinrich, Alexander Szameit +1
Exceptional points facilitate peculiar dynamics in non-Hermitian systems. Yet, in photonics, they have mainly been studied in the classical realm. In this work, we reveal the behav…
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…
Quantum Random Number Generation using a Solid-State Single-Photon Source
Simon J. U. White, Friederike Klauck, Toan Trong Tran +8
Quantum random number generation (QRNG) harnesses the intrinsic randomness of quantum mechanical phenomena. Demonstrations of such processes have, however, been limited to probabil…
