Tensor Network Simulation of the Heisenberg Model on Heavy-Hex Lattices
Paolo D'Alberto
We extend CppSim, a high-performance C++/HIP tensor network simulator, to the heavy-hex lattice geometry used in superconducting quantum processors. The heavy-hex graph -- a bipart…

GPU-First Heisenberg-Picture Tensor Network Dynamics for the 2D Transverse-Field Ising Model
Paolo D'Alberto
We present CppSim, a C++/GPU 2D Ising simulator for Heisenberg-picture tensor network time evolution on GPUs. The key computational contributions are: first, a zero-malloc GPU work…
