Numerical Simulation of Large Scrambling Quantum Circuits

ORAL

Abstract

As Noisy Intermediate-Scale Quantum (NISQ) devices are becoming more available, it is important to identify meaningful physics inspired problems beyond randomized quantum circuits. In my talk I will present our latest large scale simulations of quantum scrambling circuits, with the goal to understand how quantum correlation propagates between qubits. As part of my talk, I will introduce the scrambling circuits used in our simulations and the numerical techniques (both exact and approximate) used to verify and benchmark the Sycamore@Google quantum chip.

The project is in collaboration with P. Roushan, C. Quintana, I. Aleiner, Y. Chen, X. Mi and V. Smelyanskiy, and other members of the Google Quantum AI team.
