Scaling law of variational quantum algorithms

Abstract:We study scaling law of variational quantum algorithms by large-scale numerical experiments on combinatorial optimizations. On experiments up to n = 5000 qubits with O( log(n)) circuit depth with a classically simulable ansatz, the converged energies consistently differ by no more than 0.5% from the optimal or reference energies reported in the benchmarks.
