The paper outlining the work, published in the journal Nature this morning, comes a month after a draft was unintentionally posted on a NASA server. It demonstrates that a quantum processor consisting of 54 superconducting quantum bits, or qubits, was able to perform a random sampling calculation - essentially verifying that a set of numbers is randomly distributed - exponentially faster than any standard computer.
