Floquet engineering in a dissipatively protected subspace — •Liz Burton and Francesco Petiziol — TU Berlin, Hardenbergstraße 36, Berlin

A possible approach to quantum error correction is to encode information in the degenerate ground state of a gapped physical system, where correctable errors correspond to excitations of the system and are thus energetically penalized. Error correction is realized "passively", without active manipulation of the system, through dissipation processes that relax the system to the ground state. In our work, we consider a physical realization of the three-qubit code as an Ising model coupled to a bath that implements the necessary dissipative channels. We investigate how to realize logical operations in the code space by means of Floquet engineering techniques. Moreover, one of our major goals is to shed light on the interplay between the Floquet scheme and dissipative protection, and how it impacts the efficiency of the quantum error correction code.

Keywords: Floquet engineering; quantum error correction; three-qubit code
