About the project

This project explores quantum machine learning, specifically quantum kernel methods, to enable efficient spike sorting for resource-constrained neural recording systems. The goal is to overcome computational limitations of current methods, facilitating real-time applications like brain-computer interfaces and portable neurotechnology.

This project will investigate whether quantum machine learning (QML) approaches, particularly quantum kernel methods, can enable efficient spike sorting for resource-constrained neural recording systems. Extracellular neural recording systems capture electrical activity from populations of neurons, producing mixed signals that must be computationally separated, a process known as spike sorting. As neural recording technologies advance, enabling simultaneous recording from increasingly large neuronal populations, the computational demands of spike sorting have grown substantially. 

Current high-performing approaches (such as Kilosort and MountainSort) often require significant computational resources, limiting their suitability for low-cost, embedded, or real-time applications like brain-computer interfaces (BCIs), neural prosthetics, and portable neurotechnology. Quantum machine learning, particularly hybrid quantum-classical models, offers a novel framework for classification in low-dimensional feature spaces. Quantum kernel methods may provide an efficient way to represent complex decision boundaries while maintaining a tractable processing pipeline suitable for deployment in low-cost systems.
