Influence of Spin Decoherence on the Yield of Photodriven Quantum Teleportation in Molecular Triads.

The evolution of spin coherences due to spin-selective recombination in the system with three unpaired electrons is discussed. It is shown that in the case of bidirectional kinetics, the decoherence processes can significantly change the quantum yield of the products. This enables one to discriminate between approaches that model spin-selective recombination but predict different decoherence rates. The rigid donor-acceptor-radical molecular triad is suggested to study the decay rate of singlet-triplet coherence. A modification of the photodriven quantum teleportation protocol is proposed to measure the quantum yields of the monoradical products.
