摘要
En 中文
We develop and analyze a method for simu-lating quantum circuits on classical computers by representing quantum states as rooted tree tensor networks. Our algorithm first deter-mines a suitable, fixed tree structure adapted to the expected entanglement generated by the quantum circuit. The gates are sequentially applied to the tree by absorbing single-qubit gates into leaf nodes, splitting two-qubit gates via singular value decomposition and thread-ing the resulting virtual bond through the tree. We theoretically analyze the applicability of the method as well as its computational cost and memory requirements and identify advan-tageous scenarios in terms of required bond dimensions as compared to a matrix product state representation. The study is comple-mented by numerical experiments for different quantum circuit layouts up to 37 qubits.
