Prepare \(\left\vert A,B\right\rangle =\left\vert {g}_{2},{g}_{1}\right\rangle\) and measure the population in \(\left\vert A,B\right\rangle =\left\vert {g}_{1},{g}_{2}\right\rangle\) as a function of spin detuning and delay. a Diagram showing the two spin-phonon coupling schemes. The active spins A and B are highlighted in red and blue which are connected to the common phononic channel by Raman facilitated process, while other spins denoted by the black sphere are inactive and remain “dark” to the phonon. b “Chevron” interference pattern as we tune the two spin frequencies in the opposite direction w.r.t. the phonon mode. c Population swapping between the two spins as we keep them aligned but vary the common detuning to the phonon mode. Interference between distant qubits is revealed by the detuning of the qubit frequency.
