quantlop#

High-performance quantum simulation for matrix-free Hamiltonian evolution

Memory-efficient

Directly apply Pauli words without storing the dense representation of the Hamiltonian matrix.

Multi-threaded

Run serially by default or enable OpenMP parallel execution with an explicit thread count.

PennyLane and Qiskit

Build Hamiltonians directly from PennyLane Hamiltonian and Qiskit SparsePauliOp objects.
