Six research and industry collaborators have come together under the QSPEC initiative to create a quantum-based measurement system that has the potential to revolutionize the verification of food authenticity. This project aims to transition from traditional laboratory analyses, which often require specialized equipment, to compact and rapid tools that can be used widely.
Funded by the German Federal Ministry for Research, Technology, and Space, the consortium seeks to utilize entangled photon pairs to detect fraudulent practices in products like honey and orange juice, two items notoriously prone to counterfeiting globally. By leveraging the unique behavior of long- and short-wavelength photons, this innovative system promises unparalleled sensitivity and precision that far surpasses traditional spectroscopy methods.
Food fraud results in significant economic losses annually and introduces serious health hazards. Currently, confirming food authenticity is often an intricate and time-consuming process. The vision for QSPEC is to develop a compact and budget-friendly quantum spectroscopy system capable of rapidly analyzing food composition.
The partnership includes AMO GmbH, the Photonic Quantum Technologies group at Leibniz University Hannover, TOPTICA Photonics SE, AMOtronics UG, the German Institute of Food Technologies (DIL), and the Laser Zentrum Hannover (LZH). Together, they are focused on creating essential components such as:
– Innovative laser sources for entangled photon production
– Nanophotonic chips that incorporate quantum-optical functionalities
– Temperature-stabilized detection equipment
– Reference databases to validate results
Initial achievements involve the successful generation of entangled photon pairs using AMO-designed chips and the provision of two laser systems fine-tuned for quantum frequency comb applications.
As the project progresses, the next step involves refining the laboratory prototype into a more compact version, with DIL assessing its performance against established NIR and NMR techniques. The long-term goal is to scale this technology for industrial use, ultimately developing a device small enough to fit into a smartphone, allowing for immediate authenticity checks at the point of purchase.
The overarching objective of the QSPEC project is to envision a future in which consumers, retailers, and regulatory agencies can verify the true contents of food products with unmatched speed, accuracy, and simplicity.
