What the SEQUOIA Consortium developed is a quantum imaging technique that achieves 0. 5-micron resolution, potentially revolutionizing early detection of eye diseases. Funded by the €4. 5 million Horizon Europe program, this breakthrough combines quantum physics and artificial intelligence to surpass the limitations of current Optical Coherence Tomography (OCT) systems. While conventional OCT struggles to resolve details below 1 micron, SEQUOIA’s approach uses quantum-entangled photons and AI-driven control to probe tissue at finer scales. This could enable clinicians to identify subtle retinal changes earlier, improving diagnostic accuracy and patient outcomes. The project remains in the feasibility phase, but its potential to advance preventative eye care is substantial.
Quantum Entanglement Enhances Retinal Imaging Resolution
The SEQUOIA consortium is pioneering a new retinal imaging technique leveraging the principles of quantum entanglement to dramatically improve resolution. Current Optical Coherence Tomography (OCT), the standard for examining the retina, struggles to resolve details smaller than 1 micron, roughly one hundredth the width of a human hair. This limitation hinders early detection of subtle structural changes indicative of diseases like macular degeneration, glaucoma, and diabetic retinopathy. The SEQUOIA project aims to surpass this barrier, potentially achieving resolutions down to 0. 5 microns, offering a significantly sharper view of the retina’s delicate layers.
This enhanced resolution is made possible by utilizing quantum-entangled photons to illuminate retinal tissue. Unlike classical light sources, these entangled pairs allow imaging of sub-micron structures that would otherwise remain invisible. According to the SEQUOIA team, this approach has the potential to reveal the earliest signs of disease, such as cellular swelling or thinning, before irreversible damage occurs. Building on this, sharper image edges will help clinicians more easily distinguish between healthy and damaged tissue, reducing diagnostic uncertainty and improving patient outcomes.
The project, funded by a €4. 5 million Horizon Europe grant, represents a feasibility study to investigate the potential of quantum OCT. Dr. Patrick Bowen Montague, coordinator of SEQUOIA, clarified that the current focus is on testing the technology, rather than developing a finished product. However, successful demonstration of 0. 5-micron resolution would lay the groundwork for future imaging systems capable of detecting disease at its earliest stages, potentially preventing vision loss and improving the lives of millions. The team hopes to provide clinicians with information at scales previously unattainable with existing technology.
“At this stage, it’s a feasibility study; we are testing the potential, not a finished product.”

AI-Driven Quantum Imaging for Early Eye Disease Detection
The SEQUOIA project is heavily integrating artificial intelligence to process the complex data generated by this new quantum imaging technique. According to the consortium, conventional image reconstruction methods struggle with the noise inherent in quantum signals, limiting the clarity and diagnostic potential. Advanced machine learning algorithms are being developed to filter this noise and enhance the subtle features within retinal scans, effectively translating raw quantum data into clinically useful images. This AI-powered processing is crucial for identifying the earliest indicators of eye diseases, which often manifest as extremely minor structural changes.
Building on this, the AI isn’t simply used for post-processing; it’s also integral to optimizing the quantum imaging process itself. The SEQUOIA team is employing reinforcement learning to dynamically adjust the parameters of the quantum light source and detection system. This allows the system to adapt to individual patient characteristics and maximize the signal-to-noise ratio for each scan. Furthermore, the AI algorithms are trained on vast datasets of retinal images, enabling them to identify patterns and anomalies that might be missed by human observers. This automated analysis could significantly reduce the time required for diagnosis and improve the accuracy of assessments.
This integration of AI and quantum imaging has the potential to move eye disease diagnosis from reactive to proactive. The ability to detect structural changes at the 0. 5-micron level, coupled with AI-powered analysis, could allow clinicians to identify individuals at high risk of developing conditions like macular degeneration or glaucoma before symptoms appear. This early detection opens the door to preventative treatments and interventions that could slow disease progression or even prevent vision loss altogether. The consortium believes this technology represents a significant step towards personalized ophthalmology, tailoring diagnostic and treatment strategies to each patient’s unique needs and risk factors.
“Our aim is to investigate whether quantum OCT can provide clinicians with information at smaller scales than today’s systems”

This breakthrough by the SEQUOIA project could enable earlier and more accurate diagnoses of debilitating eye diseases. Achieving 0. 5-micron resolution represents a significant leap beyond current imaging capabilities, potentially revealing subtle retinal changes previously undetectable with standard Optical Coherence Tomography.
For industries relying on high-resolution medical imaging, this development offers a pathway toward preventative care. The implications extend beyond ophthalmology, as the combination of quantum entanglement and artificial intelligence pioneered by the SEQUOIA consortium may inspire new approaches to biomedical diagnostics. Ultimately, this research could help clinicians preserve vision and prevent blindness through timely intervention.
