Google Quantum AI introduces a new quantum algorithm called Quantum Echoes for measuring Out-of-Time-Order Correlators (OTOCs), demonstrating a verifiable quantum advantage on the Willow quantum chip, and paving the way for solving real-world problems like Hamiltonian learning in NMR.

## Evidence

Verbatim from https://research.google/blog/a-verifiable-quantum-advantage/:

> In our latest Nature publication, we introduce a new quantum computational task measuring Out-of-Time-Order Correlators (OTOCs). This work demonstrates a verifiable quantum advantage and paves the way for solving real-world problems like Hamiltonian learning in Nuclear Magnetic Resonance (NMR).
