High-speed $R_{Z Z}$ gates in Kerr-cat qubits via fast-forward scaling

Takaaki Aoki, Shumpei Masuda

Kerr parametric oscillators can encode Kerr-cat qubits, whose biased-noise nature can reduce the hardware overhead required for fault-tolerant quantum computation. In a recently pr…

Inter-transition interference in spectrum of Kerr parametric oscillators

Shumpei Masuda

We theoretically investigate reflection and transmission measurements of two-photon and four-photon Kerr parametric oscillators (KPOs), introducing interference effects between int…
