Description
The promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor 1. A fundamental challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space. Here we report the use of a processor with programmable superconducting qubits 2, 3, 4, 5, 6, 7 to create quantum states on 53 qubits, corresponding to a computational state-space of dimension 2 53 (about 10 16). Measurements from repeated experiments sample the resulting probability distribution, which we verify using classical simulations. Our Sycamore processor takes about 200 seconds to sample one instance of a quantum circuit a million times—our benchmarks currently indicate that the equivalent task for a state-of-the-art classical supercomputer would take approximately 10,000 years.
