Hardware efficient fault tolerance calculation using superconducting circuit

摘要

A technique is provided that provides hardware-efficient fault-tolerant quantum computation. In some embodiments, the cavity and the Ancylla transmon encode logical qubits using more than two energy levels of the cavities, and encode the information using more than two energy levels of the Ancylla transmon. , Is used to implement quantum operations by creating an interaction between the cavity and the Ansilla transmon, separating at least one type of error in the Ancilla transmon from the cavity.
