Generally speaking, no. However, correlation within the noise spectrum can enhance and perhaps even promote quantum coherence and entanglement between otherwise decoupled qubits. In my talk, I'll discuss a model we are developing which considers the dynamics of otherwise decoupled & localized qubits that interact via a common environment. I will discuss how correlated and anti-correlated noise can enhance fidelity of prepared Bell states, enhance (or retard) the propagation of a state along a spin chain, and perhaps lead to spontaneous synchronization of qubits.
