Entangled electron spin states at work in spin dependent molecular processes

摘要

There are summarized our results obtained when studying the entangled electron-hole pairs by the direct and indirect electron paramagnetic resonance methods. These results demonstrate rather peculiar response of the spins in the entangled state to the manipulations with the external microwave fields: intensities of lines in the electron paramagnetic resonance spectra should oscillate; the echo type signal is expected as the response to only one microwave pulse; the primary spin echo signal has anomalous phase compared to the phase of the echo signal in a case of spins in a non-entangled state; the two-quantum transitions can be manifested even in the absence of the spin-spin interaction if the electron paramagnetic resonance is detected indirectly, e.g., optically. A possible scenario for the quantum teleportation experiment is suggested.
