TL;DR: Un unconditional teleportation of massive particle qubits using atomic (9Be+) ions confined in a segmented ion trap is reported, which achieves an average fidelity of 78 per cent, which exceeds the fidelity of any protocol that does not use entanglement.

TL;DR: The creation of cat states of up to six atomic qubits is reported, which represents the current state-of-the-art for large entangled states in any qubit system.

TL;DR: In this article, the authors describe a randomized benchmarking method that yields estimates of the computationally relevant errors without relying on accurate state preparation and measurement, since it involves long sequences of randomly chosen gates, and also verifies that error behavior is stable when used in long computations.

TL;DR: In principle, the approach enables a quantum state to be maintained by means of repeated error correction, an important step towards scalable fault-tolerant quantum computation using trapped ions.
