论文摘要
我们提出了一种用于微域热纯量子(TPQ)方法的量子算法,该算法通过与一些最近开发的量子奇异值转换得出的技术相结合,在评估有限温度下的热力学量方面具有优势。如果已经确切地获得了量子系统的地面能,则有效地实现了哈密顿量的多种产物,并且在量子计算中系统地构建了低温下的TPQ状态。
We present a quantum algorithm for the microcanonical thermal pure quantum (TPQ) method, which has an advantage in evaluating thermodynamic quantities at finite temperatures, by combining with some recently developed techniques derived from quantum singular value transformation. When the ground energy of quantum systems has already been obtained precisely, the multiple products of the Hamiltonian are efficiently realized and the TPQ states at low temperatures are systematically constructed in quantum computations.
