ABSTRACT
Quantum state teleportation is commonly used in designs for large-scale quantum computers. Using Quantinuum's H2 trapped-ion processor, we demonstrate fault-tolerant circuits a error correction code-specifically the Steane code. The use up to 30 qubits at physical level and employ real-time correction. We conducted experiments on several variations of logical using both transversal gates lattice surgery. measured process fidelity be 0.975 ± 0.002 implementation 0.851 0.009 surgery as well 0.989 an Knill-style
