A little more for you:

"Document ID: 20190030475 Quantum Supremacy Using a Programmable Superconducting Processor The tantalizing promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor. A fundamental challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space. Here, we report using a processor with programmable superconducting qubits to create quantum states on 53 qubits, occupying a state space 2(exp53) ~ 10(exp16). Measurements from repeated experiments sample the corresponding probability distribution, which we verify using classical simulations. While our processor takes about 200 seconds to sample one instance of the quantum circuit 1 million times, a state-of-the-art supercomputer would require approximately 10,000 years to perform the equivalent task. This dramatic speedup relative to all known classical algorithms provides an experimental realization of quantum supremacy on a computational task and heralds the advent of a much-anticipated computing paradigm. 20190801 August 2019 Copyright, Public use permitted Unclassified, Unlimited, Publicly available http://hdl.handle.net/2060/20190030475 CASI application/pdf Mandra, Salvatore Rieffel, Eleanor G.

This must be the experiment they ran to show quantum supremacy
