第一性原理量子蒙特卡罗
First principles quantum Monte Carlo
摘要：
目前的量子蒙特卡罗代码使用适合于找到量子系统的振幅或相关本征值的统计技术。因此，它们不使用真正的物理随机源。它表明，事实上，量子概率承认一个描述的基础上的一个特定的类的随机过程，至少在单粒子的情况下。然后，可以构造精确模拟量子动力学的第一性原理蒙特卡罗程序。解释了关于如何映射振幅干扰中的随机选择的微妙问题。该代码在模拟单次打击实验可能的优势进行了讨论。
英文摘要：
Present quantum Monte Carlo codes use statistical techniques adapted to find the amplitude of a quantum system or the associated eigenvalues. Thus, they do not use a true physical random source. It is demonstrated that, in fact, quantum probability admits a description based on a specific class of random process at least for the single particle case. Then a first principle Monte Carlo code that exactly simulates quantum dynamics can be constructed. The subtle question concerning how to map random choices in amplitude interferences is explained. Possible advantages of this code in simulating single hit experiments are discussed.
