Query: Engineering fast bias-preserving gates on stabilized cat qubits   Stabilized cat codes can provide a biased noise channel with a set of
bias-preserving (BP) gates, which can significantly reduce the resource
overhead for fault-tolerant quantum computing. All existing schemes of BP
gates, however, require adiabatic quantum evolution, with performance limited
by excitation loss and non-adiabatic errors during the adiabatic gates. In this
work, we apply a derivative-based leakage suppression technique to overcome
non-adiabatic errors, so that we can implement fast BP gates on Kerr-cat qubits
with improved gate fidelity while maintaining high noise bias. When applied to
concatenated quantum error correction, the fast BP gates can not only improve
the logical error rate but also reduce resource overhead, which enables more
efficient implementation of fault-tolerant quantum computing.
