论文摘要
我们介绍了TQIX.PIS，TQIX库，用于旋转合奏的量子动力学模拟。该库通过量子电路模拟动态过程，包括初始化量子状态，执行量子运算符和测量最终状态。它利用旋转集合中的集体过程来缩小尺寸从指数缩小到二次粒子的数量，即量子状态在dicke的基础上跨度。 It also facilitates the simulation time with multi-core processors and Graphics Processing Units.因此，该库适用于模拟具有集体特性的大量粒子的集合。可以使用库模拟各种现象，例如自旋挤压，变异量子挤压，量子相变和多体量子动力学。
We introduce tqix.pis, a library of tqix, for quantum dynamics simulation of spin ensembles. The library emulates a dynamic process by a quantum circuit, including initializing a quantum state, executing quantum operators, and measuring the final state. It utilizes collective processes in spin ensembles to reduce the dimension from exponentially to quadratically with the number of particles, i.e., the quantum state spans in Dicke basis. It also facilitates the simulation time with multi-core processors and Graphics Processing Units. The library is thus applicable for the simulation of ensembles of large number of particles that have collective properties. Various phenomena, such as spin squeezing, variational quantum squeezing, quantum phase transition, and many-body quantum dynamics, can be simulated using the library.
