Titre Fault-tolerant operations on an encoded qubit
Résumé A fault-tolerant architecture based on error-corrected qubits requires logical gates and error syndrome measurements that prevent the spreading of uncorrectable errors. In this talk, I will present a fault-tolerant construction for gates and parity measurements on a cavity-encoded logical qubit. The scheme uses the multilevel structure of a transmon ancilla, along with RF-tunable transmon-cavity interactions, to apply a broad range of operations on a variety of encodings, while protecting the logical qubit against photon loss, as well as ancilla decay and dephasing. These results present an important step towards fully fault-tolerant processing of logical qubits.
