We taught a quantum computer to learn from its own mistakes-- without stopping.
Our RL framework repurposes QEC detection events as learning signals to stabilize the system.
Result: Improved Logical Error Rates for both Surface and Color codes on Willow!

Great work worth a read if you work on superconducting circuit with flux control!
This weekend I tried another home experiment for my toddler. This one was suggested to me by none other than Michel Devoret!
It’s pretty cool. But I was more excited than the kid 😅
Are you a computer scientist and don't know what an OTOC is, but want to understand the problem solved in the recent Nature paper by Google Quantum AI? We wrote a 2-page note that explains the motivation and presents a simplified version of the problem for any input size.

Google Deep Mind in collaboration with Google Quantum put on arxiv their new decoder AlphaQubit 2.
They show high accurancy and fast ML decoding on surface code and Colo(u)r code!
Its exciting to start seeing high accuracy and fast decoder for the color code!

The same quantum tunneling honored by this year’s #NobelPrize is driving #URochesterResearch

Well, so much for my post about learning something new this Nobel week! The Physics prize went to J. Clarke, M. Devoret, and J. Martinis, the pioneers of my own field, superconducting circuits. An absolutely foundational work, and so well-deserved.

I cannot decide what's my favorite slop: The single qubit CNOT gate or the tentative to make a graph for a bell pair or maybe the new notation ∣0^2 and ∣1 ^1 .

Another experiment with my son (4yo)! We use this baby nasal aspirator to show the Venturi effect!
Blowing air through the horizontal tube creates a low-pressure zone at the T-junction, sucking the liquid right up the vertical tube.
Coloring the water is the trick to get my son to pay attention
Nobel Prize week is almost here. I enjoy the predictions, but the real highlight for me is the forced exposure to science outside my field. It’s the one week I get a proper dive into research I’d otherwise miss.
