A New Spin on Organic Molecular Qubits

ORAL

Abstract

Optically-addressable spin qubits are a powerful platform for quantum sensing technologies, offering the potential to detect weak signals with unprecedented sensitivity and atomic spatial resolution. Recent efforts in the engineering of these qubit sensors have mostly focused on solid-state and molecular systems with ground-state spins, which are less common and lack some of the advantages of their ubiquitous excited-state spin counterparts. Here, we develop a new technique that enables us to optically address the spin state of a fluorophore commonly used for bioimaging, and characterize its optical and spin properties up to room temperature. This paves the way for a new generation of organic molecular spin qubits for quantum information science.
