  • Quantum Supremacy Using a Programmable Superconducting Processor

    December 4, 2019

    Dr. Roushan discusses using a processor with programmable superconducting qubits to create quantum states on 53 qubits. The system, Google's Sycamore processor, required about 200 seconds to sample one instance of a quantum circuit a million times, while the equivalent task for a classical supercomputer would take approximately 10,000 years. This dramatic increase in speed compared to all known classical algorithms is an experimental realization of quantum supremacy for this specific computational task.
