Quantum supremacy using a programmable superconducting processor
Google Quantum AI
A critical question for the field of quantum computing is whether quantum devices without error correction can perform a well-defined computational task beyond the capabilities of state-of-the-art classical computers, achieving so-called quantum supremacy. I will describe the recent result of reaching this milestone with Google quantum computer. I will describe the computational task, sampling from the output distributions of (pseudo-) random quantum circuits and discuss the physics aspects of the quantum chaotic evolution that gave rise to the distribution in question. I will provide an overview of the experiment with 53 qubits, design of superconducting qubit system, benchmarking procedures for the high-fidelity quantum gates and multi-qubit quantum circuits.
