Dynamical decoupling and quantum error correction with SU(d) symmetries
Colin Read, Eduardo Serrano-Ensástiga, John Martin
Dynamical decoupling is a long-established and effective way to suppress unwanted interactions in qubit systems, enabling advances in fields ranging from quantum metrology to quant…

Symmetric Resourceful Steady States via Non-Markovian Dissipation
Baptiste Debecker, Eduardo Serrano-Ensástiga, Thierry Bastin +2
We prove a no-go theorem for symmetry-based dissipative engineering of collective-spin steady states: in spin-only Lindblad dynamics with jump operators linear in the collective-sp…
