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…

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…

Observation-dependent suppression and enhancement of two-photon coincidences by tailored losses

Max Ehrhardt, Matthias Heinrich, Alexander Szameit

The uncanny ability of multiple particles to interfere with one another is one of the core principles of quantum mechanics, and serves as foundation for quantum information process…
