Strongly correlated quantum walks with a 12-qubit superconducting processor

2019 · Science

Quantum walks are the quantum analogs of classical random walks, which allow for the simulation of large-scale quantum many-body systems and the realization of universal quantum computation without time-dependent control. We experimentally demonstrate quantum walks …
