Hybrid QEC and Logical Dynamical Decoupling: Co-Design Criteria for Quantum Memory

USC researchers derive closed-form fidelity criteria for hybrid logical dynamical decoupling + QEC protocols, proving LDD+QEC beats QEC-only when LDD suppresses minimum-weight uncorrectable errors. Co-design of code, decoder, and decoupling group is essential.
