microstate
From Physics wiki
A microstate is a condition of a system that distinct from any other condition, in that specifying which microstate a system is in is equivalent to specifying every knowable aspect of every part of the system. A microstate is usually the same as a pure quantum state.
The collection of all allowable microstates of a system is known as a microcanonical ensemble.
