SUPER excitation protocol enables ultrafast, non-resonant, spin-conserving optical control of tin-vacancy centers in diamond

We demonstrate ultrafast coherent control of tin-vacancy centers in diamond using femtosecond and SUPER excitation. This scheme enables spin-conserving, non-resonant population transfer and spectral separation of laser and emission for quantum spin-photon interfaces.
