Organic dye molecules as possible candidates for spin-photon interfaces — •Max Masuhr and Daqing Wang — Institute of Physics, University Kassel, Heinrich-Plett-Straße 40, Kassel, Germany

Polycyclic hydrocarbon molecules are bright photon emitters, exhibiting high quantum efficiencies and narrow transition linewidths when embedded in matrices and cooled to liquid helium temperatures. The synthetic flexibility of molecules allows for tuning of their emission wavelengths and makes them promising candidates for linking with other quantum systems. Apart from the favorable photon emission properties between the singlet states, the long-lived triplet states in these molecules provide opportunities for quantum information storage. Here, we discuss lifetime measurements of the triplet states and investigate the feasibility of realizing a spin-photon interface based on the singlet-triplet transition in a single molecule.
