While a number of breakthroughs have been made in donor-based qubit systems, the small dipole moment of donor spins makes inter-connection of many qubits challenging. Acceptor spins, on the other hand, possess spin-orbit coupling, which offers a spin qubit with a large electric dipole moment. However, static and dynamic properties of acceptor spins have yet to be unveiled in experiments. Towards realisation of an acceptor qubit, we investigate spin relaxation and spin coherence for two different kinds of spin level configurations of boron atoms, in both single atom and ensemble measurements.
