Reducing the measurement errors in nonadiabatic holonomic quantum computers

引用

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 64-70页

作者： guo-fu Xu Department of Physics Shandong University

Nonadiabatic holonomic quantum computers serve as the physical platform for nonadiabatic holonomic quantum *** quantum computation has entered the noisy intermediate-scale era, building accurate intermediate-scale nonadiabatic holonomic quantum computers is clearly necessary. Given that measurements are the sole means of extracting information, they play an indispensable role in nonadiabatic holonomic quantum computers. Accordingly, developing methods to reduce measurement errors in nonadiabatic holonomic quantum computers is of great importance. However, while much attention has been given to the research on nonadiabatic holonomic gates, the research on reducing measurement errors in nonadiabatic holonomic quantum computers is severely lacking. In this study, we propose a measurement error reduction method tailored for intermediate-scale nonadiabatic holonomic quantum computers. The reason we say this is because our method can not only reduce the measurement errors in the computer but also be useful in mitigating errors originating from nonadiabatic holonomic gates. Given these features,our method significantly advances the construction of accurate intermediate-scale nonadiabatic holonomic quantum computers.

我国行政公诉不同于西方国家行政公诉的特点,我国行政公诉既是一种公力救济,又具有典型的监督属性,它始终以公权力监督为贯穿主线,体现为对行政权的直接监督、有限监督。从公共利益优先权和公力救济有限性的角度界定行政公诉的范围,将督促行政主体履行职责作为提起行政公诉的前置程序,以节省诉讼成本,提高监督效率。基于检察机关拥有特别的公权力,检察监督具有明显的司法性、专门性、专业性,以及为了防止行政公诉的恣意,诉讼中应当以检察机关负举证责任为原则,行政机关仅对其控制的行政信息情报、规范性文件以及公害案件涉及的高度专业性、技术性问题负责举证。
