Abstract
Quantum metrology enables some of the world's most sensitive measurements with transformative potential for the life sciences. However, translating qubit sensors into practical tools for monitoring cellular processes or detecting disease remains a major challenge. In this talk, I will discuss how combining quantum engineering with molecular biology can overcome these barriers and enable a new generation of biologically integrated quantum sensors. I will present advances in biocompatible surface functionalization for highly coherent diamond sensors, core-shell nanodiamonds with engineered spin coherence, and, finally, an entirely new class of biological qubits based on optically addressable spins in fluorescent proteins. These genetically encodable protein qubits combine nanometer-scale dimensions with coherence and optical readout approaching those of solid-state defects. Together, these advances illustrate how integrating quantum engineering with molecular biology opens new opportunities for quantum sensing in the life sciences, with applications ranging from fundamental biology to biomedical diagnostics.
