近日，南郵通信與信息工程學院的科研團隊在金剛石NV色心量子磁強計的研製上取得了重大突破。團隊首次采用金剛石NV色心固態量子體係實現了0.01T–1.5T磁場範圍的量子精密測量。金剛石NV色心量子磁強計空間分辨率達到微米尺寸
，而全球知名的瑞士Metrolab公司的PT2025型核磁共振磁強計探頭尺寸為毫米尺度
，對待測磁場的梯度有嚴苛的要求，通常要求小於1000 ppm/cm。金剛石NV色心量子磁強計由於磁場敏感核心物質隻有微米尺寸
，有望解決大磁場梯度缺乏量子計量技術的難題。團隊通過使用新鬆多可機器人GCR5-910，tigaolexinpianbiaomianweibocichangzidonghuaceshishuipinghejingdu，zaikongzhijingduhebianlixingshangdouyoulejudadetisheng，yichenggongshixiandangeyuanzhuyongcitibiaomiancichangqiangdudezisuyuanxianweiceliang。
