The GANDALF algorithm cleans up noisy snapshots of atomic qubits, speeding up readout and reducing errors by a factor of 35.

Each qubit glows with just a few hundred photons. An algorithm inspired by photo editors guesses the state from noisy snapshots. Quantum computers stop waiting and start computing — with errors 35 times rarer.

🎯 Each qubit emits just a handful of photons — as much light as the eye catches from a barely visible star. It is this microscopic signal that GANDALF amplifies.
