Entanglement suppression

What is it about?

In chemistry, it is widely used assumption that microparticles (atoms, molecules or ions) in a solution bear high level of individuality, i.e. high level of independence of their environments. This long standing foundational issue is here addressed via a model of suppressing entanglement in a tripartite quantum system - a model of quantum particles individuality.

Why is it important?

Entanglement between a particle and the solvent molecules system can be reduced for macroscopic time intervals by proper pressing on the environment--a kind of the externally-induced quantum Zeno effect for the environment. In effect, the particle exhibits approximately unitary dynamics for a long time period.
