- Abstract: One of the fundamental arguments in quantum information theory is the
uncertainty principle. In accordance with this principle, two incompatible
observables cannot be measured with high precision at the same time. In this
work, we will use the entropic uncertainty relation in the presence of quantum
memory. Considering a dissipative environment, the effects of the detuning
between the transition frequency of a quantum memory and the center frequency
of a cavity on entrpic uncertainty bound and quantum correlation between
quantum memory and measured particle will be studied. It is shown that by
increasing the detuning, quantum correlation is maintained. As a result, due to
the inverse relationship between the uncertainty bound and quantum correlation,
the measurement results is guessed more accurately.
