![]() 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. It is crucial that the resource requirements Specifically, we consider a tree-cluster code as an inner loss-tolerant code concatenated with an outer 5-qubit code for protection against Pauli errors. ![]() Download a PDF of the paper titled Resource-efficient fault-tolerant one-way quantum repeater with code concatenation, by Kah Jen Wo and 7 other authors Download PDF Abstract: One-way quantum repeaters where loss and operational errors are counteractedīy quantum error correcting codes can ensure fast and reliable qubit To this end, we propose a one-way quantum repeater that targets both the loss and operational error rates in a communication channel in a resource-efficient manner using code concatenation.
