Abstract :
We propose a scheme to control the collision-induced entanglement between atoms in the two-site Bose-Hubbard model, by means of site-indiscriminate noise. This decoherence mechanism induces the continuous measurement of the quasi-momentum, protecting single-particle coherence via a Bose-enhanced many-body Quantum-Zeno effect.
