A team of engineers and physicists at quantum computing company Quantinuum has successfully conducted the first-ever teleportation of a logical qubit using fault-tolerant methods. This groundbreaking achievement, published in the journal Science, opens new horizons for quantum computing. The researchers worked with their H2 trapped-ion quantum processor, employing transversal and lattice surgery methods to transport logical qubits with high fidelity. Real-time decoding using the Steane code played a crucial role in error correction throughout the process, marking a significant advancement in quantum computing.

Innovative Teleportation Methods
This will take approximately three to four hours and the Quantinuum team demonstrated methods for teleporting logical qubits using both transversal and lattice surgery. It worked by doing multiple operations on several qdbits at the same time, reducing the resources for teleportation. Conversely, lattice surgery was oriented toward qubit boundary manipulation compatible with a wider array of architectures. Both methods were effective at removing artifactual stimulation but the transversal approach exhibited stronger fidelity. The team’s unique approach to quantum teleportation involved the real-time decoding of the Steane code for error correction at critical phases.
