# Quantum error-correction record brings useful computers closer

Researchers have set a record in quantum error correction, a key step toward making quantum computers reliable enough for practical use. The advance matters because correcting errors is essential for scaling quantum machines beyond fragile experimental systems.

**Importance:** 3/5
