一类可以有效模拟的量子多体态

A class of quantum many-body states that can be efficiently simulated

G. Vidal

摘要:

我们介绍了多尺度纠缠重整化模型(MERA),一个有效的表示某些量子多体状态的D维晶格。等效于具有对数深度和独特因果结构的量子线路,MERA允许对局部期望值进行精确评估。它也是纠缠重整化的基础结构,这是一种针对晶格上量子系统的粗粒度方案,专注于保持纠缠。

英文摘要:

We introduce the multi-scale entanglement renormalization ansatz (MERA), an efficient representation of certain quantum many-body states on a D-dimensional lattice. Equivalent to a quantum circuit with logarithmic depth and distinctive causal structure, the MERA allows for an exact evaluation of local expectation values. It is also the structure underlying entanglement renormalization, a coarse-graining scheme for quantum systems on a lattice that is focused on preserving entanglement.
