A Biologically-Compatible Molecular Spin Qubit

ORAL

Abstract

Advances in biology often arise from novel techniques which offer enhanced sensitivity, resolution, chemical specificity, or minimize invasiveness. Quantum sensing offers the potential to detect weak signals with unprecedented sensitivity. Optically addressable spin qubits are particularly promising sensors for biological applications because of their inherent nanoscale size. However, these spins are often embedded in solid state hosts which are large and difficult to tag to target biomolecules. Meanwhile, biologists have developed a library of high performance fluorophores for biological imaging. Here, we optically address the spin state of a common fluorescent tag. We characterize the spin's properties and estimate its sensitivity to magnetic fields. Together, these results position a biocompatible qubit with applications for sensing, cellular imaging and medical diagnostics.
