最近提出了一种构造量子纠错码的方案，该方案将有限维码空间嵌入到由连续量子变量描述的系统的无限维希尔伯特空间中。该方案的难点之一是编码状态的准备。我们将展示如何通过将连续量子变量耦合到单个量子比特来生成这些状态。离子阱量子计算机为耦合到量子位的连续系统提供了自然设置。我们讨论了如何在离子阱中产生编码态。
Recently a scheme has been proposed for constructing quantum error-correcting codes that embed a finite-dimensional code space in the infinite-dimensional Hilbert space of a system described by continuous quantum variables. One of the difficult steps in this scheme is the preparation of the encoded states. We show how these states can be generated by coupling a continuous quantum variable to a single qubit. An ion trap quantum computer provides a natural setting for a continuous system coupled to a qubit. We discuss how encoded states may be generated in an ion trap.
