Interview with António Costa: Where 2D Materials Meet Quantum Innovation

Since earning his PhD in 1998, António Costa—Associate in the Rossier Research Group—has dedicated his research to the theoretical exploration of low-dimensional magnetic systems, with a particular emphasis on spin excitations. By combining analytical approaches with computational modeling, he investigates how magnetic materials respond to external influences such as magnetic fields and electrical currents, uncovering fundamental mechanisms that underpin their behavior. Your research focuses on 2D materials and the interface between plasmonics and magnonics. What recent breakthroughs stand out in your work?On the magnonics side, we have been studying the spin excitations of a new kind of magnetic materials called altermagnets. These have properties that are sort of in-between ferromagnets and antiferromagnets. We have demonstrated that the lifetime of magnons in metallic altermagnets can be highly anisotropic, a property that can be exploited technologically to guide magnons along certain paths in the material. Further details can be found in the publication here.On the magnonics/plasmonics interface, we have shown that graphene plasmons can couple strongly to the low-energy magnons in a 2D insulating ferromagnet, which can be uses as a new way to probe magnons in 2D materials, and also as a way to convert a magnetic into an electric signal and […]

Graphene-based biosensor breaks detection records for non-invasive monitoring of diabetes

A breakthrough biosensor detects glucose in human tears at ultra-low concentrations, opening new avenues for wearable health monitoring technologies. In a significant leap toward the future of diabetes care, INL researchers have developed a graphene-based biosensor capable of detecting glucose at attomolar levels—representing the lowest detection limits ever achieved for this crucial biomarker. It’s comparable to finding a single grain of sugar dissolved in an entire lake. The study, published in the Journal of the American Chemical Society and led by Dr. Andrea Capasso at INL, introduces an ultra-sensitive glucose sensor based on graphene field-effect transistor (GFET) technology. Engineered to operate with extremely small volumes of biological fluid – down to a single tear -, this device has the potential to revolutionise glucose monitoring, particularly in non-invasive and wearable systems. The researchers developed a targeted graphene functionalisation using glucose oxidase (GOx), enabling highly selective glucose recognition. They then employed advanced spectroscopic and microscopic techniques to analyse the graphene’s chemical composition and surface modifications at each stage of functionalisation, from enzyme immobilisation to interaction with the target analyte. “While finger-prick sensors remain the clinical standard for diabetes monitoring, they are often perceived as uncomfortable and invasive,” says Dr. Capasso. “Our goal […]

No assumptions: just quantum advantage

INL researcher Michael de Oliveira, together with collaborators from the University of Cambridge and the Hon Hai (Foxconn) Quantum Computing Research Center, has published a new article in Nature Communications demonstrating that even small, noisy quantum circuits can outperform certain types of classical computation, without relying on assumptions or ideal conditions. This study focuses on constant-depth quantum circuits, meaning that all operations happen in parallel in a very short time – like multiple people completing a task simultaneously rather than one after another. The researchers show that these simple quantum circuits can solve specific problems that no classical circuit of the same kind and size can solve, even when those classical circuits are modelled after neural networks, with tuneable flexibility. The classical models studied here (biased threshold circuits) are used in theoretical models of machine learning and resemble basic neural networks. Despite the authors considering versions with low bias – and therefore greater versatility – they are still outperformed by shallow quantum circuits, even when the quantum devices are noisy or imperfect. What makes this breakthrough particularly important is that it applies to qudits (quantum systems that go beyond binary bits or qubits), and the results are valid across all […]

Advancing neuronal research using 3D polymeric micro-scaffolds integrated with quantum sensors

A recent research study from INL has successfully merged two cutting-edge 3D tissue engineering strategies – 3D polymeric scaffolds and 3D neuronal spheroids – to create a highly advanced model for studying neuronal behaviour and disease. The collaboration between biomedical engineers, physicists, and neuroscientists has led to the development of a smart polymeric scaffold integrated with fluorescent nanodiamonds, that reveals to be a powerful quantum sensing tool. These low auto-fluorescence scaffolds, fabricated using laser-based 3D microprinting, were designed to be both biocompatible and capable of hosting 3D neuronal spheroids. The fluorescent nanodiamonds embedded within the scaffolds provide the potential for real-time monitoring of magnetic signals and temperature shifts at the nanoscale, providing a new level of precision in studying cellular signalling, disease mechanisms, and drug responses. Beatriz Costa, the first author of this study, emphasises the significance of the work: “The use of low-autofluorescence 3D polymeric scaffolds enabled the integration of quantum metrology techniques with nanodiamonds. When combined with 3D neuronal cell aggregates, this approach holds great potential for in-depth studies of neurodegenerative diseases and beyond.” The study’s success lies in its ability to use these scaffolds to host dopaminergic neurons, crucial to Parkinson’s disease research, and demonstrate the neurons’ […]
