Specifically, we consider a tree-cluster code as an inner loss-tolerant codeĬoncatenated with an outer 5-qubit code for protection against Pauli errors. Quantum repeater that targets both the loss and operational error rates in aĬommunication channel in a resource-efficient manner using code concatenation. Of such repeaters, for example, the number of qubits per repeater node and theĬomplexity of the quantum error correcting operations are kept to a minimum toĪllow for near-future implementations. Wallman Fault-tolerant quantum computation requires non-destructive quantum measurements with classical feed-forward.
