In a recent paper, we showed that secondary storage can extend the range of quantum
circuits that can be practically simulated with classical algorithms. Here we refine those
techniques and apply them to the simulation of Sycamore circuits with 53 and 54 qubits, with
the entanglement pattern ABCDCDAB that has proven difficult to classically simulate with
other approaches. Our analysis shows that on the Summit supercomputer at Oak Ridge

In a recent paper, we showed that secondary storage can extend the range of quantum circuits that can be practically simulated with classical algorithms. Here we refine those techniques and apply them to the simulation of Sycamore circuits with 53 and 54 qubits, with the entanglement pattern ABCDCDAB that has proven difficult to classically simulate with other approaches. Our analysis shows that on the Summit supercomputer at Oak Ridge National Laboratories, such circuits can be simulated with high fidelity to arbitrary depth in a matter of days, outputting all the amplitudes.
