Something that turns scrambled signals back into clean, usable information.

Quantum computers make errors constantly — and fixing them in real time was a huge bottleneck. On 22 Sep 2026, IonQ announced the industry's first real-time quantum error decoder that runs on a single ordinary CPU, correcting errors across millions of operations without slowing the machine down.
The decoder is the quantum computer's proof-reader
Qubits are fragile — noise corrupts them mid-calculation. A decoder watches the errors happen and translates the messy, error-riddled signal back into the correct answer, fast enough to keep up. That was the bottleneck: fixing errors used to need a supercomputer and still caused pauses. IonQ's version runs on one off-the-shelf CPU and added as little as 0.02% delay. Decode = de- (undo) + code (the message).
Keep it: decoder = un-scrambler. Your phone does it every time it turns radio waves into a video call.
