Could not imagine working without stim, it’s an incredibly useful and fast tool.

Scaling and logic in the color code on a superconducting quantum processor Quantum error correction is essential for bridging the gap between the error rates of physical devices and the extremely low logical error rates required for quantum algorithms. Recent error-correctio...

Second, also out today from Nathan Lacroix, Alexandre Bourassa, Kevin Satzinger, and the rest of the Google Quantum AI is a realization of the color code, complete with logical operations! Check it out here: arxiv.org/abs/2412.14256

Thanks to my colleagues @mattmcewen.bsky.social , @amorvan.bsky.social, and the rest of the Google Quantum AI team! These circuits were first proposed by @mattmcewen.bsky.social , Dave Bacon, and @craiggidney.bsky.social ( arxiv.org/abs/2302.02192 )

Here we realize three novel QEC implementations:

- the surface code embedded on a hexagonal lattice
- a walking surface code
- the surface code using iSWAP gates instead of CZ gates,

each enabling a new avenue for design and optimization of QEC circuits and hardware.

Demonstrating dynamic surface codes A remarkable characteristic of quantum computing is the potential for reliable computation despite faulty qubits. This can be achieved through quantum error correction, which is typically implemented ...

Check out our latest quantum error correction preprints from the team at Google Quantum AI! In the first, we demonstrate three time-dynamic implementations of the surface code, each with state-of-the-art performance enabled by Willow devices: arxiv.org/abs/2412.14360

The fabulous world of GKP codes Quantum error correction is an essential ingredient in the development of quantum technologies. Its subject is to investigate ways to embed quantum Hilbert spaces into a physical system such that this...

Hi all!

I just uploaded my recently defended thesis, I hope you like it. Hit me up if you want to chat about anything GKP/QEC or life. :)
