Paderborn University

Paderborn University is a German public research university whose physics and electrical engineering departments host the Institute for Photonic Quantum Systems (PhoQS), a research centre funded by the state of North Rhine-Westphalia. Its work centres on integrated quantum photonics, including periodically poled lithium niobate waveguide sources of photon pairs, semiconductor quantum-dot single-photon emitters, and on-chip photonic circuits for quantum information processing. As a university rather than a company, it contributes components and device-level research to the field instead of selling quantum hardware or cloud access.

New Method Generates Photons That Are Virtually Indistinguishable

Researchers at Paderborn University, the University of Basel, and Ruhr University Bochum demonstrated a photon source based on biexciton decay in quantum dots placed inside an optical cavity. The method increased the indistinguishability of emitted photons from about 60% to roughly 90%. The work is reported in Physical Review Letters.

OutlookPlausible

If the biexciton-cavity source can be fabricated repeatably, it could be integrated into prototype photonic quantum processors, improving two-photon interference fidelity and supporting more reliable on-chip entanglement generation within the next two years.
