标题： Fast, high fidelity information transmission through spin chain quantum wires

摘要： 自旋链已被提出作为固态量子架构中信息传输的量子导线。 我们表明，使用仅依赖于一个局部的开关执行器的极简控制方法，可以在传输速度和保真度方面获得巨大的提升。 可以使用优化技术确定理想和无序链的有效切换时间序列。 模拟表明，即使在没有准确模型的情况下，也可以进行有效的优化。 显示英文摘要

摘要： Spin chains have been proposed as quantum wires for information transfer in solid state quantum architectures. We show that huge gains in both transfer speed and fidelity are possible using a minimalist control approach that relies only a single, local, on-off switch actuator. Effective switching time sequences can be determined using optimization techniques for both ideal and disordered chains. Simulations suggest that effective optimization is possible even in the absence of accurate models.
