Efficient tensor network simulation of IBM's largest quantum processors

arXiv:2309.15642v3 Announce Type: replace-cross
Abstract: We show how quantum-inspired 2d tensor networks can be used to efficiently and accurately simulate the largest quantum processors from IBM, namely Eagle (127 qubits), Osprey (433 qubits) and Condor (1121 qubits). We simulate the dynamics of a complex quantum many-body system -specifically, the kicked Ising experiment considered recently by IBM in Nature 618, p. 500-505 (2023)- using graph-based Projected Entangled Pair States (gPEPS), which was proposed by some of us in PRB 99, 195105 …
