Title: Towards Experimental Realization of Topological Floquet Models in Circuit QED
Abstract: Topological band structures are well known to produce symmetry-protected chiral edge states which transport particles unidirectionally. These same effects can be harnessed in the frequency domain using a spin-1/2 system subject to periodic drives. Previously, the topological regime of such models was thought to be experimentally inaccessible due to a need for ultrastrong coupling; however, recent results have shown that the desired Hamiltonian is achievable in a rotating frame and can give rise to translations of non-classical states of light in a cavity in the Fock basis which we call "boosting". The native strong light-matter coupling in circuit QED along with tunable qubits allows us to tune the system into the regime where boosting can occur. Here I will present the design we have developed to achieve the strong driving necessary to reach the topological pumping regime and discuss our progress towards realizing boosting.
