Abstract: We will describe recent work from our laboratory that focuses on using photo-driven processes to generate entangled electron spins in molecular materials targeting applications in quantum computing, communications and sensing. We will describe how ultrafast photogeneration of radical ion pairs within covalent organic electron donor-acceptor systems results in two entangled spins having sufficiently long coherence times to perform CNOT gate operations and to teleport a prepared quantum state on a third spin to one of the spins comprising the entangled pair. We will also describe recent work using photogenerated entangled spin pairs to serve as molecular electric field sensor. Finally, we will show how singlet exciton fission in single crystals of a molecular chromophore results in the formation of two spin-coherent triplet excitons that evolve into a long-lived spin quintet state potentially useful for quantum logic operations. These results illustrate the versatility of molecular materials in quantum information science.
