论文摘要
未来的量子计算机将需要忠实操作的量子误差校正。校正功能带有用于在编码量子位上执行容忍失误的逻辑操作的开销。实施逻辑操作的最有效资源的方法之一是晶格手术，可以合并并分开安排在格子上的物理量子台，以实现纠缠大门并传送逻辑信息。在这里，我们报告了两个Qubit Ion trap量子量子信息处理器中两个拓扑编码量子位之间晶格手术的实验实现。特别是，我们证明了两个逻辑Qubits之间的纠缠，并实施了逻辑状态传送。
Future quantum computers will require quantum error correction for faithful operation. The correction capabilities come with an overhead for performing fault-tolerant logical operations on the encoded qubits. One of the most resource efficient ways to implement logical operations is lattice surgery, where groups of physical qubits, arranged on lattices, can be merged and split to realize entangling gates and teleport logical information. Here, we report on the experimental realization of lattice surgery between two topologically encoded qubits in a 10-qubit ion trap quantum information processor. In particular, we demonstrate entanglement between two logical qubits and we implement logical state teleportation.
