Universal Dynamical Control of Open Quantum Systems

Figure 6

Average modified final decoherence rate 𝑅(𝑇), normalized with respect to the unmodulated rate, as a function of energy constraint. DD—dash, magenta. Optimal modulation—solid, blue. Insets: optimal modulation Ω(𝑡) for different energy constraints. (a) Single-peak resonant dephasing spectrum (inset: 𝐸=20). (b) Single-peak off-resonant spectrum (inset: 𝐸=50). (c) 1/𝑓 spectrum (inset: 𝐸=30). (d) Multipeaked spectrum (inset: 𝐸=30).
