Errors in quantum computers are inevitable. A new approach with moving neutral atoms lets logical qubits correct errors on the spot, boosting accuracy up to 8-fold.

Quantum computers based on neutral atoms are tripped up by slow state readout. The GANDALF program acts like a filter in a photo editor: it takes a short, noisy exposure and reconstructs a clear signal, doubles the speed of error correction, and slashes failures by tens of times.
