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…
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…
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…
