Here, we propose a robust scheme to realize an entangling gate for distant solid-state spins via a mechanical oscillator in its thermal equilibrium state.

Here we overcome this challenge with engineered quantum sensing sequences that achieve both, enhanced robustness and the simultaneous suppression of higher order harmonic resonances.

We experimentally demonstrate that the performance of the spin sensor is robust against dephasing due to a self protected machanism. The SiC thermometry may provide a promising platform for sensing in a noisy environment ,e.g. biological system sensing.

We demonstrate theoretically that it is possible to detect the effect of the geomagnetic field on the radical pair reaction and propose the present scheme as a possible hybrid model chemical compass.
