- Abstract: Future quantum computers will require quantum error correction for faithful
operation. The correction capabilities come with an overhead for performing
fault-tolerant logical operations on the encoded qubits. One of the most
resource efficient ways to implement logical operations is lattice surgery,
where groups of physical qubits, arranged on lattices, can be merged and split
to realize entangling gates and teleport logical information. Here, we report
on the experimental realization of lattice surgery between two topologically
encoded qubits in a 10-qubit ion trap quantum information processor. In
particular, we demonstrate entanglement between two logical qubits and we
implement logical state teleportation.
