Molecular qubits are extensively tunable, in contrast to other spin qubits. The use of spin ensembles as quantum repeaters in quantum communication relies on strong coupling between photon and spin modes. Here we show that the effective coupling strength depends on the magnetic interactions between the spins in the ensemble.
与其他自旋量子比特相比，分子量子比特具有广泛的可调性。在量子通信中使用自旋系综作为量子中继器依赖于光子与自旋模式之间的强耦合。在这里，我们表明有效耦合强度取决于系综中自旋之间的磁相互作用。
