Assessing the Robustness of the Clock Transition in a Mononuclear S = 1 Ni(II) Complex Spin Qubit

Ni­(II) complexes with an integer spin S = 1 that behave as clock transition spin qubits at zero magnetic field are resilient to magnetic fluctuations of the spin bath, while Co­(II) complexes with a half-integer spin (S = 3/2) lose their coherence when they are subject to the same fluctuating magne...

Abstract Ni­(II) complexes with an integer spin S = 1 that behave as clock transition spin qubits at zero magnetic field are resilient to magnetic fluctuations of the spin bath, while Co­(II) complexes with a half-integer spin (S = 3/2) lose their coherence when they are subject to the same fluctuating magnetic field as the Ni­(II) ones. These findings demonstrate that adequately designed Ni­(II) complexes are excellent candidates for spin qubits.
