论文摘要
量子绝热转移广泛用于量子计算和量子模拟中。但是，传输速度受量子绝热近似条件的限制，该条件阻碍了其在量子系统中的应用，其反应时间很短。在这里，我们演示了量子绝热状态转移，这些转移以一量和两量的超导通传输沿大地测量学沿着地球化学跳跃。与通常的绝热过程相比，这种方法具有速度，鲁棒性和高保真度的优势。我们的协议提供了可行的策略，以改善超导量子电路中的状态操作和门操作。
Quantum adiabatic transfer is widely used in quantum computation and quantum simulation. However, the transfer speed is limited by the quantum adiabatic approximation condition, which hinders its application in quantum systems with a short decoherence time. Here we demonstrate quantum adiabatic state transfers that jump along geodesics in one-qubit and two-qubit superconducting transmons. This approach possesses the advantages of speed, robustness, and high fidelity compared with the usual adiabatic process. Our protocol provides feasible strategies for improving state manipulation and gate operation in superconducting quantum circuits.
