Abstract
Bosonic codes use nonclassical bosonic states to encode and process quantum information, which renders them hardware-efficient compared to codes with two-level systems. However, it is still a challenging task to prepare high-quality bosonic code states with high efficiency. In our recent work [Phys. Rev. Lett. 132 , 023602 (2024)], we developed a noncommutative Fourier transformation technique and the new method to generate arbitrary Hamiltonian in the Floquet phase space of a periodically driven oscillator. We establish the relationship between an arbitrary target Floquet Hamiltonian in phase space and the periodic driving potential in real space. Our protocol can be realized in a range of experimental platforms for nonclassical state generation and bosonic quantum computation.
