Towards operating an error correcting code with noise biased bosonic qubits Part 1

Biased noise qubits can improve the hardware efficiency of error correcting codes by allowing them to primarily focus on correcting one type of error. To leverage this advantage, it is critical that the noise bias be preserved not just while idling, but during all circuit operations. We perform an experiment to study the performance of an error correcting code in a biased noise architecture using transmons and cat qubits.

In the first part of the talk series, we introduce the architecture in use and characterize the components and gates of our circuit.
