论文摘要
我们介绍了核可观察物的量子计算，其中首先根据单位的线性组合对感兴趣的操作员进行分解。然后，我们利用Hadamard测试和基于单位的方法（LCU）方法来计算期望值。我们应用这些方法来计算杜特隆的电二极管。比较了Jordan-Wigner转换和灰色代码编码的结果。我们讨论了我们的方法的多功能性，该方法通常可以用来计算量子计算机上的几个可观察力。
We present the quantum computation of nuclear observables where the operators of interest are first decomposed in terms of the linear combination of unitaries. Then we utilise the Hadamard test and the linear combination of unitaries (LCU) based methods to compute the expectation values. We apply these methods to calculate the electric quadrupole moment of deuteron. The results are compared for the Jordan-Wigner transformation and Gray code encoding. We discuss the versatility of our approach that can be utilized in general to calculate several observables on a quantum computer.
