近日，北京理工大学姚裕贵院士，珠海校区量子材料珠港澳国际研究中心张先鹏研究员与巴西圣保罗大学Jose Carlos Egues教授在超导量子测量领域取得重要进展。研究团队提出了一种基于动态干涉超导电流(Dynamic Interference Supercurrent)的 Andreev 量子比特读出新方案，利用量子比特自身的相干演化产生的宏观振荡超导电流，实现对任意量子叠加态的高精度、近无损读出。该方案无需引入辅助量子比特，也无需在每次测量后反复重置量子比特，有望显著降低量子测量的实验复杂度，为超导量子计算中的高效量子态测量与量子信息读取提供新的思路。相关研究成果以 “Andreev qubit readout from dynamic interference supercurrent” 为题，发表于国际物理学期刊《Physical Review B：Letter》114, L080502（2026）。
