Quantum computers promise to perform certain computational tasks exponentially faster than classical processors. However, achieving these speed-ups requires sufficiently low error rates in the quantum processor. In this talk, I will discuss the development of a programmable quantum processor named Sycamore, which consists of 53 superconducting qubits with state of the art operational fidelities. We benchmark the performance of Sycamore on randomly generated quantum circuits which are significantly more complex than any previous quantum computation. We also show that the performance of the Sycamore device is well predicted by a simple model, confirming that the principles of quantum computing work at scale. Finally, I will discuss progress towards the ultimate goal of quantum computing – a fault-tolerant error corrected quantum computer.
