Quantinuum teleports a logical qubit with real-time error correction

Apr 25, 2024

Quantinuum uses up to 30 trapped ions to teleport an encoded quantum state while correcting errors during the circuit. Different protocols reach process fidelities of 97.5% and 85.1%; this is a laboratory operation within one processor.

Why it matters

Teleportation with error correction is a building block for moving and processing protected quantum information.
