Happy World Quantum Day! Today’s #GoogleDoodle represents the potential of the qubit. We’re harnessing its unique quantum properties to build systems capable of solving problems that remain intractable for classical computers →

Today in nature, we published a breakthrough demonstration of verifiable quantum advantage using a measurement known as out-of-time-order correlator (OTOC), or Quantum Echoes. Performed on our Willow chip, it paves a path toward real-world applications →

Willow is the most advanced quantum chip yet, designed for state-of-the-art performance and flexibility. Our tunable qubits and couplers enable fast gates and operations, leading to improved performance across many metrics. Check it out → #QuantumAI

A quantum computing milestone almost 30 years in the making. Our new Willow chip uses surface codes to achieve exponential suppression of errors “below threshold”. This breakthrough paves the way for larger, more (cont)

Quantum computers aren’t what you think. They’re cooler. Watch our #TED2024 TED Talk from Hartmut Neven, founder &amp; head of Google Quantum AI → See how a quantum computer works, learn about quantum fundamentals, current and future applications, and more.

Level up your quantum expertise. Enroll in our free Coursera course on quantum error correction from Google Quantum AI and become a contributor to the next era of computing. → →

In nature, researchers from Google Quantum AI, TU München, &amp; UoN Physics & Astronomy simulated a (2+1)D lattice gauge theory and visualized string dynamics, revealing the deconfined-to-confined excitation transition as the effective electric field increases. →

Random Circuit Sampling (RCS) is a necessary benchmark to measure quantum computer performance in the presence of noise. Why is RCS considered a cornerstone of quantum computing? Find out in our latest breakdown. #QuantumAI

The future of quantum computing relies on overcoming errors. Quantum error correction is how we'll build reliable and scalable quantum systems. What excites you most about the potential of quantum error correction? #QuantumAI

In honor of World Quantum Day, we’re heading onto our campus to answer the top trending questions people are searching for. Join Jenna and Andrew from our team as they break down the basics of quantum and what these systems could actually be used for →

Our team ran a verifiable quantum algorithm that probes how parts of a quantum system interact, from molecules to magnets and beyond. On our Willow chip, it ran 13,000× faster than the best classical supercomputers. A first in quantum computing →

We demonstrated verifiable quantum advantage with Quantum Echoes. Running 13,000x faster than leading supercomputers, this represents a significant step toward real-world applications. Watch →

Did you know quantum processors must be kept near absolute zero, colder than deep space? These temperatures reduce noise and maintain quantum coherence, making quantum computing possible.

Building quantum computers faces a core challenge: control qubits without losing info. Hear from Yu Chen, Director, Quantum Processor, on the “secret sauce” behind Willow. It let Quantum Echoes run 13,000x faster, a verifiable quantum advantage. Read →

Hear from Michel Devoret, our Chief Scientist of Quantum Hardware, on our latest breakthrough algorithm: Quantum Echoes. His early work on superconducting artificial atoms laid the foundation for the Willow chip, enabling verifiable quantum advantage.

Communicating with qubits is tricky, they must stay isolated to preserve their state yet still “hear” our signals. Our researchers are developing control systems that send commands and collect data without disturbing their fragile quantum states →

Using random circuit sampling (RCS), we've demonstrated that quantum computers can outperform classical supercomputers, even with noise. This 'beyond classical' capability is possible because qubits can exist in multiple states at once, giving quantum computers an edge.

In honor of today’s ceremonies, we celebrate 2025 Nobel Laureate in Physics, Michel Devoret! He shares the prize with John Martinis &amp; John Clarke for the foundational circuits that became the basis of our quantum chips today. Watch Michel's incredible journey.

As we approach the International Year of Quantum, Willow, our latest chip, brings us closer to fault-tolerant quantum computing. Learn more →

Behind building a quantum computer lies a world of subtle sounds. This ASMR journey invites you into the lab’s quiet rhythms, gentle hums, and intricate patterns of work, offering a glimpse into the focus and precision that drive scientific discovery.

Recently published in nature, Decoded Quantum Interferometry (DQI), a new quantum algorithm achieving exponential speedup on select optimization problems. Learn more →

With UC Berkeley, we tested Quantum Echoes by predicting two molecular structures on Willow and confirming them via NMR spectroscopy. This is an exciting exploration of the potential of quantum computing in studying molecular properties.

Willow performed benchmark task, random circuit sampling, in under 5 minutes that would take the world's fastest supercomputer 10 septillion years - longer than the age of the universe. Click the link to learn more about Willow: #QuantumAI

Most of what you see in a quantum computer is mostly infrastructure. The real processing happens on a chip as small as the palm of a hand, where quantum states are manipulated with extreme precision →

Quantum processors rely on superconductivity, which only emerges at extremely low temperatures. Using dilution refrigeration, we cool systems to 0.01 kelvin, colder than outer space →

What comes to mind when you hear "NISQ"? This term encapsulates both the potential and the challenges of today's quantum computers. Leave a comment about what you’re looking forward to beyond the NISQ era. #QuantumAI

To celebrate #WorldQuantumDay we want to share with you our vision of quantum computing's future impact. From medicine to new energy, we're working with the international quantum ecosystem to help solve impossible problems. Learn more →

Although powerful, quantum computing is not seamless. Noise is an inevitable phenomenon that is a result of inherent randomness and uncertainty that can lead to computation errors. Google's Quantum AI team is looking for ways to mitigate this and uncover new insights.
