研究还揭示了巨型超原子与光相互作用的内在机制,并展示了两种具有实用潜力的耦合构型:在紧密排 列下,量子态可在多个巨型超原子间无损传递;而在远距离精确连接条件下,光波或声波可保持相位一 致,从而实现量子信号定向发送与远距离纠缠。 该工作目前仍处于理论阶段,研究团队计划进一步推进其实验制备。由于该概念可与其他量子系统结 合,也为发展混合量子平台提供了新思路。团队指出,通过智能设计降低硬件复杂性,巨型超原子或将 成为迈向实用化量子技术的关键一步。 (文章来源:科技日报) 研究团队此次提出的"巨型超原子"模型,融合了"巨型原子"与"超原子"两类人造量子结构的特性。其 中,巨型原子具有多个空间分离的耦合点,可同时与环境中的光波或声波相互作用,其发射的波可返回 并影响原子自身,形成类似"回声"的量子效应,从而抑制退相干并赋予系统记忆能力。超原子则是由多 个天然原子共享量子态、整体表现为单一量子实体的结构。 将二者结合形成的巨型超原子,能够以集体形式运作,实现光与物质之间的非局域相互作用。这一设计 使得多个量子比特的信息可被存储和控制于一个单元内,减少对外部复杂电路的依赖。更重要的是,该 系统有望克服以往巨型原子在实现量子 ...

离量子世界更进一步!我国科研团队成功掌握量子系统热化节奏

给量子系统"加热"好似给一块冰升温。一开始温度上升很快,随后进入冰和水共存的阶段。此时即便继续加热,温度依旧长时间卡在0℃不再上升,因为能 量被用来"融冰"而不是升温。量子系统中也出现了类似情形——外界不断输入能量,但系统并没有立刻变得混乱,而是停留在一个相对稳定的"预热化平 台"。通过改变加热的方式和节奏,科学家可以调节平台的持续时间。只有当这个阶段结束后,系统才会像冰完全融化后那样,内部状态迅速变得复杂。此 时信息在整个系统中扩散,其复杂程度经典计算机已经无法算准。 经济观察网据央视新闻客户端消息,记者从中国科学院物理研究所获悉,该所科研团队和合作者们通过实验,掌握了量子系统的热化节奏,使人们离理解和 控制高度复杂的量子世界又更近了一步。相关成果1月28日在国际学术期刊《自然》发表。 科研团队在一块包含78个量子比特的超导芯片"庄子2.0"上进行了实验,不仅发现了预热化平台和可控规律,还展示了量子芯片在模拟复杂系统上的独特优 势。就像科幻里的"MOSS"能预测复杂演化一样,现实中的量子计算机也能掌握那些经典计算机算不清的节奏。通过这样的研究,使我们离理解和控制高度 复杂的量子世界又更近了一步。 在科幻电影 ...
