Simulation:   distributed computing

For n=33 qubits, 128 GB of memory is required just for the array of quantum amplitudes. On a single 128 GB node this causes swapping, and the run-time increases to 43832 seconds (about 12 hours) which is a factor of 36 times what would be expected following the exponential scaling (20 minutes). For n=34 qubits a single node has insufficient memory and can not perform the simulation.
