Solid-State Quantum Coherence From a High-Spin Donor-Acceptor Conjugated Polymer.

ABSTRACT: Molecular spin systems that can be chemically tuned, coherently controlled, and readily integrated within devices remain central to the realization of emerging quantum technologies. Organic high-spin materials are prime candidates owing to their similarity in electronic structure to leading solid-state defect-based systems, light element composition, and the potential for entanglement and qubit operations mediated through spin-spin exchange. However, the inherent instability of these species precludes their rational design, development, and application. Here, the first example of an organic high-spin qubit based on a conjugated polymer semiconductor comprised of alternating dithienosilole and thiadiazoloquinoxaline heterocycles is demonstrated. It is shown that electron spins within the ma
