macroscopic state

[¦mak·rə¦skäp·ik ′stāt]
(statistical mechanics)
Any state of a system as described by actual or hypothetical observations of its macroscopic statistical properties. Also known as macrostate.

In other words, a macroscopic state exhibiting no quantum mechanical interference appears to arise from some sort of co-operation among the infinity of subsystems.
Quantum mechanics (without the infinity assumption) predicts that superpositions of macroscopic states will be observed in such systems.
These are tunable quantum systems with properties that emerge from the strong interaction between coherent units, with macroscopic states that are determined by collective quantum many-body physics.
as a certain amount of a gas, a crystal, a pointer on a volt meter, a cat, human beings) is crucial since it makes it clear that although also governed by quantum mechanics, nonetheless, the combination of the enormous number of quantum states in the macroscopic object eliminates the quantum interference between macroscopic states, say, two human beings.
Recently, this situation has improved, as scientists find that while it may be difficult to prove the quantumness of macroscopic states, it is not impossible.
