Studying particle diffusion in quantum systems is a major classical computing challenge. Our Willow processor was used to demonstrate disorder-free localization via a quantum algorithm which offers a polynomial speedup for disorder sampling.

A scientific dialogue. Building on Bulchandani, Burnell & Sondhi, we implemented a scalable GHZ game. This result has sparked theirs on classical strategy upper bounds. Excited to see where this conversation leads.

Arjuna: “What does Google’s Willow quantum processor share with the Sundarbans forest?”
Rishi: “They both host the largest cats on earth- Schrödinger’s cat and the Bengal tiger.”

Our @ScienceMagazine perspective : have quantum simulators already found new physics ?
Think hot-air balloons: tricky to fly, not very steerable, but once aloft can drift into unexplored territory and make real “discoverinos.”

New breakthrough quantum algorithm published in @Nature today: Our Willow chip has achieved the first-ever verifiable quantum advantage.
Willow ran the algorithm - which we’ve named Quantum Echoes - 13,000x faster than the best classical algorithm on one of the world's fastest supercomputers. This new algorithm can explain interactions between atoms in a molecule using nuclear magnetic resonance, paving a path towards potential future uses in drug discovery and materials science.
And the result is verifiable, meaning its outcome can be repeated by other quantum computers or confirmed by experiments.
This breakthrough is a significant step toward the first real-world application of quantum computing, and we're excited to see where it leads.

In @Nature, we show a "stable computationally complex phase" is reachable with current quantum processors. Even with noise, these quantum computers can perform calculations that are beyond the capabilities of classical supercomputers. art design by @SayoStudio
Working with researchers at @GoogleQuantumAI is pretty incredible! Today, @Nature published, "Phase transitions in random circuit sampling". Our SayoStudio illustration/animation by Melanie Lee explores a quantum phase transition and incoherent noise. nature.com/articles/s41586-0…

Publishing in @ScienceMagazine , we engineer dissipative reservoirs that can steer many-body quantum systems toward low entropy steady states, establishing engineered dissipation as an alternative for preparing entangled states on NISQ processors.

Noise destroys long-range correlations on quantum processors and hinders the coherent evolution in the nominally available computational space. Using Random Circuit Sampling we estimate the effective available Hilbert space @GoogleQuantumAI

The story of Sarina Esmailzadeh reached me this morning, I'm somewhat at a loss for words. We talk about freedoms with no understanding of what it means to pay the ultimate price in fighting for it. This brave girl was only 16 years in the world...
Look at this beautiful teenage girl, full of life, singing with @Hozier 's "Take Me to Church". The Islamic Republic killed her in the protests following #MahsaAmini's murder. She only wanted to live a free life as a young woman. Say her name: #SarinaEsmailzadeh

I've had privilege to teach, learn, and collaborate with Sharif graduates (including my own Ph.D student Mohammad Mahmoody) throughout my career. They've made innumerable contributions to CS and Science at large
I'm awed by courage of students&faculty and hope humanity prevails

Is no one on #AcademicTwitter going to address the fact that armed police officers today surrounded, shot at, and arrested some of the brightest university students in the world, just because they peacefully protested for their basic human rights? #مهسا_امینی
