![]() After the system is perturbed in this way, it can be allowed to relax back to the thermal equilibrium (Boltzmann distribution) and the energy emitted during relaxation can be detected. This split, equilibrated system of spin-½ nuclei can be perturbed out of equilibrium by an energy quanta whose frequency corresponds to the ΔE value (resonance excitation). Such a separation into two sub-population of a nuclear spin-½ system under an external magnetic field \(B_o\) is called the Zeeman splitting. A coherent spin–photon interface in silicon.

Our findings pave the way for the use of molecular spins in quantum technologies and spintronics. ![]() We demonstrate coherent electrical control of the quantum spin state and exploit it to independently manipulate the two magnetically identical but inversion-related molecules in the unit cell of the crystal. We study an example of a molecular nanomagnet in which a small structural distortion establishes clock transitions (that is, transitions whose energy is to first order independent of the magnetic field) in the spin spectrum the fact that this distortion is associated with an electric dipole allows us to control the clock-transition energy to an unprecedented degree. Here we show that one path is to identify an energy scale in the spin spectrum that is associated with a structural degree of freedom with a substantial electrical polarizability. However, the electric-field sensitivities reported so far are rather weak, prompting the question of how to design molecules with stronger spin–electric couplings. Thus, recent demonstrations of electric-field sensitivities in molecular spin materials 6, 7, 8 are tantalizing, raising the viability of the quantum analogues of macroscopic magneto-electric devices 9, 10, 11, 12, 13, 14, 15. Electrical control of spins at the nanoscale offers significant architectural advantages in spintronics, because electric fields can be confined over shorter length scales than magnetic fields 1, 2, 3, 4, 5.
