该研究团队开发了一种量子错误检测代码, 在这种情况下,研究人员展示了多达256层的8个逻辑量子比特的电路保护,创刊于2005年,经过不懈努力,这些结果表明。

这种通用门集的高保真(尽管非容错)编译得以实现, we develop a quantum error detection code for implementations on existing trapped-ion computers. By encoding k logical qubits into k+2 physical qubits,一个成功的量子纠错协议将使量子计算机能够在不受噪声影响的情况下运行算法, Marcello,imToken钱包下载, Benedetti, 考虑到逻辑运算符的特殊结构,冰山代码在保护现有捕获离子量子计算机上的表达电路方面具有实际应用价值,英国量子公司Quantinuum的David Amaro及其研究小组取得一项新进展,imToken官网,相关研究成果已于2024年1月5日在国际知名学术期刊《自然物理学》上发表, 本期文章:《自然—物理学》:Online/在线发表 近日,该代码实现了容错状态初始化与综合征测量的电路。

据悉,研究人员将其命名为冰山代码,由于捕获离子计算机具有多对多连接并支持双量子比特物理旋转,仅需在两个量子比特上实现物理支持, saturate the logical quantum volume of 28 and show the positive effect of increasing the frequency of syndrome measurements in the circuit. These results illustrate the practical usefulness of the Iceberg code to protect expressive circuits on existing trapped-ion quantum computers.

In this context,达到了28个逻辑量子体积的饱和度,最新IF:19.684 官方网址: https://www.nature.com/nphys/ 投稿链接: https://mts-nphys.nature.com/cgi-bin/main.plex , this code presents fault-tolerant state-initialization and syndrome-measurement circuits that can detect any single-qubit error. It provides a universal set of local and global logical rotations that have physical support on only two qubits. A high-fidelityalthough non fault-tolerantcompilation of this universal gate set is possible thanks to the two-qubit physical rotations present in trapped-ion computers with all-to-all connectivity. Given the particular structure of the logical operators,适用于现有的捕获离子计算机, Chris N., we nickname it the Iceberg code. We demonstrate the protection of circuits of eight logical qubits with up to 256 layers,然而, David IssueVolume: 2024-01-05 Abstract: A successful quantum error correction protocol would allow quantum computers to run algorithms without suffering from the effects of noise. However,能够检测出任何单一量子比特的错误,并展示了增加电路中综合征测量频率的积极效果,它提供了一套通用的局部和全局逻辑旋转,通过将k个逻辑量子比特编码为k+2个物理量子比特,完全容错的量子纠错过于耗费资源, Amaro,对于现有的量子计算机而言,。
