Theoretical Quantum Physicist (Quantum Optics & Information)
Researcher in Theoretical Quantum Optics and Quantum Information
Location - Paris, France
About the Role
We are a Paris-based deep-tech company developing a novel physics-driven approach to quantitative blood analysis. Traditional blood testing relies on chemistry-based methods, where each molecule requires a dedicated test, specific reagents, and often separate instrumentation. This fragmented model leads to high costs, operational complexity, and long turnaround times.
Our approach rethinks molecular measurement from first principles by leveraging light as a metrological tool. Light is intrinsically fast and versatile, with multiple degrees of freedom that offer untapped potential for analysing complex biological samples. In particular, nonlinear spectroscopic interactions provide universal access to organic molecules while retaining molecule-specific fingerprints.
However, in practice, spectral congestion, overlapping contributions, and matrix effects limit conventional spectroscopy, obscuring critical molecular information. To overcome these limitations, we are reformulating light–matter interactions using non-classical states of light and intrinsic quantum properties of matter. Our goal is to engineer molecule-specific interactions mediated by structured quantum light, enabling unambiguous molecular recognition in complex biological media.
