Question

Decoherence by water?

Answer 1

If two objects (we'll say electrons) are decohered from one another, it means that they do not interact in any way. They are causally separated.  

However, I'm sure there are lots of people on this forum who could give a better explanation. I feel like I'm leaving something out

Answer 2

Quantum decoherence is the loss of quantum coherence. In quantum mechanics, particles such as electrons are described by a wave function, a mathematical description of the quantum state of a system; the probabilistic nature of the wave function gives rise to various quantum effects. As long as there exists a definite phase relation between different states, the system is said to be coherent.
