论文摘要
我们介绍了对超肉体磁性Quadrupole $^{1} \ MATHRM {s} _0 $ - $ - $ - $^{3} \ MATHRM {P} _2 _2 $中性跨质的过渡，并显示如何可访问量子模拟和量子计算的方式。通过在一维光学晶格中设计光移，我们执行高分辨率光谱，并观察磁性四极转变的特征吸收模式。 We measure an absolute transition frequency of 446,647,242,704(2) kHz in $^{88}\mathrm{Sr}$ and an $^{88}\mathrm{Sr}$-$^{87}\mathrm{Sr}$ isotope shift of +62.91(4) MHz.在原理实验实验中，我们使用此转变在光学晶格中以532 nm的间距进行了局部讲话，瑞利标准分辨率为494（45）nm。我们的结果为将磁性四极转变的应用铺平了道路，并在光学晶格中使用单位点地址。
We present a detailed investigation of the ultranarrow magnetic-quadrupole $^{1}\mathrm{S}_0$-$^{3}\mathrm{P}_2$ transition in neutral strontium and show how it can be made accessible for quantum simulation and quantum computation. By engineering the light shift in a one-dimensional optical lattice, we perform high-resolution spectroscopy and observe the characteristic absorption patterns for a magnetic quadrupole transition. We measure an absolute transition frequency of 446,647,242,704(2) kHz in $^{88}\mathrm{Sr}$ and an $^{88}\mathrm{Sr}$-$^{87}\mathrm{Sr}$ isotope shift of +62.91(4) MHz. In a proof-of-principle experiment, we use this transition to demonstrate local addressing in an optical lattice with 532 nm spacing with a Rayleigh-criterion resolution of 494(45) nm. Our results pave the way for applications of the magnetic quadrupole transition as an optical qubit and for single-site addressing in optical lattices.
