论文摘要
我们研究量子退火的分叉机理。使用具有量子数s = 1的自旋，我们构建了一个简单的模型来进行分叉。 QUTRIT可以通过筑巢两个量子台组成。我们从数值上求解Schroedinger方程，以确认基于分叉的量子退火（BQA）效果很好，并且可以有效地找到基态。结果与标准量子退火（QA）使用QA进行了比较。我们发现BQA的性能与标准质量质量检查相当，或者在某些情况下给出更好的结果。
We study a bifurcation mechanism of quantum annealing. Using spins with quantum number S=1, we construct a simple model to make a bifurcation. The qutrit can be composed by nesting two qubits. We numerically solve the Schroedinger equation to confirm that the bifurcation-based quantum annealing (BQA) works well and the ground state can be found efficiently. The result is compared with that by the standard quantum annealing (QA) using qubits. We find that the performance of the BQA is comparable to the standard QA, or gives better results in some cases.
