量子计算机，就像它们的经典计算机一样，可能会受益于可以匹配不同任务的灵活的量子位编码。对于捕获离子量子处理器，访问多种编码的常见方法是使用多个共同捕获的原子种类。在这里，我们概述了一种替代方法，通过使用长寿命的亚稳态作为有效的、可编程的第二物种，在单物种系统中实现灵活的编码功能。我们描述了启用该协议所需的一组附加捕获离子基元，并表明它们与已经运行的大型系统兼容。由 AIP Publishing 独家许可出版。
Quantum computers, much like their classical counterparts, will likely benefit from flexible qubit encodings that can be matched to different tasks. For trapped ion quantum processors, a common way to access multiple encodings is to use multiple, co-trapped atomic species. Here, we outline an alternative approach that allows flexible encoding capabilities in single-species systems through the use of long-lived metastable states as an effective, programmable second species. We describe the set of additional trapped ion primitives needed to enable this protocol and show that they are compatible with large-scale systems that are already in operation.
