Preserving Quantum Coherence in Thermal Noisy Systems Via Qubit Frequency Modulation
Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.Frequency modulation is shown to preserve quantum coherence in a thermal phase‐covariant environment only under specific noise conditions. It protects a qubit against thermal dissipation from a Lorentzian reservoir, but fails against thermal pure dephasing from an Ohmic reservoir.
