Bosonic code is a quantum error correction code which encodes the logical qubit by using the large Hilbert space of harmonic oscillator, and has attracted attention recently. The architecture of bosonic qubit is often composed of long-lived high-Q superconducting cavity and superconducting qubits. Here we will introduce our recent works to implement bosonic qubits by using such components.
