Quantum Physicist Reacts to Google's "Willow" Quantum Chip!
What do quantum physicists think about Google's new quantum computing chip Willow?! Here are some of my reflections, breaking down their blog.
It includes thinking back to Google's quantum supremacy results of 2019; explaining what quantum error correction is, and the response from the quantum community on recent milestones; and comments on what this all has to do with evidence of a quantum multiverse...
