Your intuition
is probably wrong.

The method

Built around one idea:
collapse the wrong intuition

01
01

Encounter the myth

Each case opens with a claim that feels completely true. You are supposed to believe it — at first.

02
02

Test it yourself

An interactive demo lets you poke the idea until it breaks. The simulator is one click away.

03
03

Watch it collapse

The correction lands harder because you already believed the wrong thing. That is the whole point.

Quantum error correction below the surface code threshold

Acharya, R. et al. (Google Quantum AI)

Nature

Main idea

Google Willow chip demonstrates that increasing the size of a surface code reduces the logical error rate — operating below the error correction threshold for the first time with a superconducting device. A critical milestone toward fault-tolerant quantum computing.

Google demonstrates error correction below the surface code threshold for the first time on a superconducting device — a genuine milestone on the path to fault-tolerant quantum computing.
