- Abstract summary: We report the observation of a three-photon resonant transition of charge-carrier spins in an organic light-emitting diode.
Ratios of drive-induced shifts of this line to those of two-emitting and one-photon shifts agree with analytical expressions derived from the Floquet Hamiltonian.

- Abstract: We report the observation of a three-photon resonant transition of
charge-carrier spins in an organic light-emitting diode using electrically
detected magnetic resonance (EDMR) spectroscopy at room temperature. Under
strong magnetic-resonant drive (drive field $B_1$ ~ static magnetic field
$B_0$), a $B_0$-field swept EDMR line emerges when $B_0$ is approximately
threefold the one-photon resonance field. Ratios of drive-induced shifts of
this line to those of two- and one-photon shifts agree with analytical
expressions derived from the Floquet Hamiltonian and confirm the nature of
these three-photon transitions, enabling access of spin physics to a hitherto
inaccessible domain of quantum mechanics.

Photoexcited organic chromophores appended to molecular qubits can serve as a source of spin initialization or multi-level qudit generation for quantum information applications.
Time-resolved electron paramagnetic resonance (TREPR) experiments carried out at both 85 K and room temperature reveal the formation of a long-lived spin-polarized quartet state.
Exploiting this phenomenon affords the possibility of using photoinduced triplet states in porphyrins for quantum information as a resource to polarize and magnetically couple molecular electronic or nuclear spin qubits and qudits.
