Google’s Willow quantum chip achieves the first-ever verifiable quantum advantage, running algorithms 13,000x faster than supercomputers.
In a landmark breakthrough, Google has announced that its Willow quantum chip has achieved the world’s first-ever verifiable quantum advantage — running an algorithm that outperforms the fastest classical supercomputers by over 13,000 times. This milestone marks a major step forward in bringing real-world quantum computing applications closer to reality.
A New Era of Quantum Performance
For the first time in history, a quantum computer has successfully executed a verifiable algorithm on actual hardware, a feat previously considered decades away. This achievement builds on years of innovation — from Google’s 2019 demonstration of quantum supremacy to its 2024 breakthroughs in error suppression with the Willow chip.
At the heart of this latest advancement is the Quantum Echoes algorithm, officially known as the Out-of-Order Time Correlator (OTOC). Published in Nature, this algorithm enables quantum systems to compute the structure of molecules with unprecedented precision. It represents a verifiable quantum advantage, meaning its results can be reproduced by other quantum computers of similar quality — a critical step toward practical, scalable applications.
Quantum Echoes: Listening to the Universe’s Smallest Signals
The Quantum Echoes algorithm functions like an ultra-sensitive “quantum echo.” By sending a carefully crafted signal into the system, disturbing a single qubit, and then reversing the signal’s evolution, the chip “listens” for an amplified echo produced by constructive interference — the amplification of quantum waves that strengthens measurement accuracy.
This novel method enables highly detailed insights into quantum mechanical systems — from molecules and magnetic materials to black holes — all at speeds impossible for classical machines.
Measuring the Invisible: Quantum-Enhanced Molecular Mapping
In collaboration with the University of California, Berkeley, Google’s researchers used the Quantum Echoes algorithm to study two molecules — one with 15 atoms and another with 28 atoms. The Willow chip’s results matched traditional Nuclear Magnetic Resonance (NMR) findings while revealing additional molecular details not previously observable.
This advancement acts as a “quantum-scope,” much like how telescopes and microscopes once expanded human perception. It holds vast potential for drug discovery, materials design, and biological research, offering deeper insights into how molecules interact, bind, and transform.
Towards Real-World Quantum Applications
Quantum computers are uniquely suited to model quantum mechanical phenomena — the interactions that govern atoms, particles, and molecules. As this capability expands, it promises to revolutionize fields such as medicine, chemistry, and materials science.
By enhancing NMR spectroscopy, Quantum Echoes could accelerate breakthroughs in drug discovery, helping researchers understand how potential medicines bind to targets, or enable the design of new materials for batteries, polymers, and quantum hardware.
What Comes Next
With this historic demonstration, Google has achieved a crucial step toward practical quantum computing. The company is now working toward Milestone 3 on its quantum hardware roadmap — the development of a long-lived logical qubit, a foundational element for fully error-corrected quantum systems.
As Google continues to scale its quantum technology, the potential applications are limitless — from simulating chemical reactions and optimizing energy systems to unlocking mysteries of the universe itself.
