Noise seems a problem here as it destroys quantum coherence

Weak coherent driving
Weak response
Lisbon, 8th July 2009
Weak coherent driving + weak noise give a strong coherent response.
Stochastic resonance
Noise
Lisbon, 8th July 2009
Biological systems can use noise to improve their sensitivity to weak coherent signals
Can we use this in quantum mechanics ?
Noise can be good for you in quantum mechanics too for entanglement generation and preservation !
