- Abstract: The uncertainty principle is one of the comprehensive and fundamental concept
in quantum theory. This principle states that it is not possible to
simultaneously measure two incompatible observatories with high accuracy.
Uncertainty principle has been formulated in various form. The most famous type
of uncertainty relation is expressed based on the standard deviation of
observables. In quantum information theory the uncertainty principle can be
formulated using Shannon and von Neumann entropy. Entropic uncertainty relation
in the presence of quantum memory is one of the most useful entropic
uncertainty relations. Due to their importance and scalability, solid state
systems have received considerable attention nowadays. In this work we will
consider a quantum dot system as a solid state system. We will study the
quantum correlation and quantum memory assisted entropic uncertainty in this
typ of system. We will show that the temperature in of quantum dot system can
affect the quantum correlation and entropic uncertainty bound. It will be
observed that the entropic uncertainty bound decreases with decreasing
temperature and quantum correlations decreases with increasing the temperature.

The uncertainty in the classical domain comes from the lack of information about the exact state of the system.
In this paper we investigate the issue experimentally by implementing the corresponding two-dimensional and three-dimensional guessing games.
Our results confirm that within the guessing-game framework, the quantum uncertainty to a large extent relies on the fact that quantum information determining the key properties of the game is stored in the degrees of freedom that remain inaccessible to the guessing party.
