基于超导相位量子比特系统中的非简并能量本征态，我们发展了一种绝热阿贝尔几何量子计算策略。在模拟超导相位量子比特电路中存在热涨落的情况下，对所设计的量子门的保真度进行了评估，发现其对随机误差具有相当强的鲁棒性。此外，阐明了所设计的绝热演化中的Berry相可以通过为超导量子比特开发的量子态层析成像直接检测。
We have developed an adiabatic Abelian geometric quantum computation strategy based on the non-degenerate energy eigenstates in (but not limited to) superconducting phase-qubit systems. The fidelity of the designed quantum gate was evaluated in the presence of simulated thermal fluctuation in superconducting phase qubits circuit and was found to be rather robust against the random errors. In addition, it was elucidated that the Berry phase in the designed adiabatic evolution may be detected directly via the quantum state tomography developed for superconducting qubits.
