The system also performed classical machine learning with ~79.7% accuracy on a 12-mode QPU, advancing hybrid quantum-classical computing.", "body_md": "A research collaboration between Quandela, the Center for Theoretical Physics of the Polish Academy of Sciences, and the University of Warsaw has experimentally demonstrated a quantum reservoir processing (QRP) platform capable of both classical machine learning and quantum information tasks, supported by the EU Horizon Europe QUONDENSATE Pathfinder project. The system routes single photons from a semiconductor quantum dot through a 12-mode active demultiplexer into Quandela's Belenos QPU (24 modes), with photon-number-resolving (PNR) detectors at the output. A key result is single-basis quantum state tomography: the QRP protocol reconstructs two-mode density matrices using one fixed unitary transformation, achieving mean fidelity of 0.820 versus 0.747 for a standard PNR benchmark, while also extracting purity, von Neumann entropy, and entanglement negativity. A companion experiment on Quandela's legacy 12-mode Ascella QPU applied hardware-aware perturbation training for classical binary classification, reaching ~79.7% accuracy. The underlying preprint is arXiv:2605.10471 (May 2026), per Quantum Computing Report.", "url": "https://wpnews.pro/news/quandela-demonstrates-photonic-qpu-for-quantum-machine-learning", "canonical_source": "https://letsdatascience.com/news/quandela-demonstrates-photonic-qpu-for-quantum-machine-learn-27b1dc4f", "published_at": "2026-06-27 03:08:16+00:00", "updated_at": "2026-06-27 04:09:13.682135+00:00", "lang": "en", "topics": ["machine-learning"], "entities": ["Quandela", "Center for Theoretical Physics of the Polish Academy of Sciences", "University of Warsaw", "EU Horizon Europe", "Belenos QPU", "Ascella QPU", "Quantum Computing Report"], "alternates": {"html": "https://wpnews.pro/news/quandela-demonstrates-photonic-qpu-for-quantum-machine-learning", "markdown": "https://wpnews.pro/news/quandela-demonstrates-photonic-qpu-for-quantum-machine-learning.md", "text": "https://wpnews.pro/news/quandela-demonstrates-photonic-qpu-for-quantum-machine-learning.txt", "jsonld": "https://wpnews.pro/news/quandela-demonstrates-photonic-qpu-for-quantum-machine-learning.jsonld"}}
