据国外媒体报道,量子系统内部非常脆弱,因为任何一点来自外部世界的细小干扰都会使整个系统状态崩溃。这一特性令量子存储的实现困难重重,因为很难确定其是否成功保存输入的信息。为了解决这一难题,科学家们一直在摸索如何实现会纠错的量子存储。如今,英美等国研究人员已初步设计出一套相对简单的方案,可提供量子错误控制:让来自两种不 According to foreign media reports, the quantum system is very fragile, because any small interference from the outside world will make the entire system state collapse. This feature makes quantum storage difficult to achieve because it is difficult to determine if it succeeded in saving the information entered. In order to solve this problem, scientists have been gropeing on how to achieve error correction of quantum storage. Now, researchers in Britain, the United States and other countries have initially designed a relatively simple solution that can provide quantum error control:
