Google Quantum AI
“The first to claim quantum supremacy.”
Claimed the first 'quantum supremacy' moment and is now building error-corrected logical qubits with its Willow chip.
In 2019 Google's Sycamore chip did in 200 seconds what a supercomputer would need 10,000 years for.
The Story
Google Quantum AI lab founded, hiring John Martinis's team from UCSB.
Sycamore runs a task in 200 seconds a classical supercomputer would need 10,000 years for.
Publishes evidence that scaling up reduces logical error rates — a milestone for error correction.
Willow chip demonstrates 'below threshold' error correction — errors decrease as qubits grow.
Willow completes a benchmark in 5 minutes that would take classical hardware 10 septillion years.
