Coherence protection of spin qubits in hexagonal boron nitride

Spin defects in 2D hBN are promising for magnetic field sensing but suffer from short spin coherence times. Here the authors extend the coherence time for an ensemble of spins in hBN to 4 microseconds by using a continuous microwave drive and demonstrate qubit control in a protected spin space.
