论文摘要
在$σ$电子状态下的开放壳分子的旋转结构和精细的结构导致了不同奇偶校验的Zeeman状态之间的穿越。在电场的存在下，这些横梁变得避免了。我们提出了一种算法，该算法将ISING模型编码为由$^2σ$分子的对定义的Qubits，该算法在这些避免的交叉点附近共享激发。这可用于实现可通过外部电场或磁场调整的横向场，适用于量子退火应用。我们对具有一维连接性的几个示例进行动力计算。我们的结果表明，获得有效退火解决方案的概率很高，可以通过改变退火时间来优化。
The rotational and fine structure of open-shell molecules in a $Σ$ electronic state gives rise to crossings between Zeeman states of different parity. These crossings become avoided in the presence of an electric field. We propose an algorithm that encodes Ising models into qubits defined by pairs of $^2Σ$ molecules sharing an excitation near these avoided crossings. This can be used to realize a transverse field Ising model tunable by an external electric or magnetic field, suitable for quantum annealing applications. We perform dynamical calculations for several examples with one- and two-dimensional connectivities. Our results demonstrate that the probability of obtaining valid annealing solutions is high and can be optimized by varying the annealing times.
