Universal Dynamical Control of Open Quantum Systems

Figure 13

Multipartite systems (black) coupled to their environments (red) (color online). (a) Relaxation of identical qubits via coupling to the same bath modes causes cross decoherence. (b) Different AC-Stark shifts on individual qubits couple them to different bath modes, eliminating cross decoherence. (c) Different Rabi driving of dephasing qubits is analogous to (b).
