  Originated from the work extraction in quantum systems coupled to a heat
bath, quantum deficit is a kind of significant quantum correlations like
quantum entanglement. It links quantum thermodynamics with quantum information.
We analytically calculate the one-way deficit of the generalized $n$-qubit
Werner state. We find that the one-way deficit increases as the mixing
probability $p$ increases for any $n$. For fixed $p$, we observe that the
one-way deficit increases as $n$ increases. For any $n$, the maximum of one-way
deficit is attained at $p=1$. Furthermore, for large $n$ ($2^n \rightarrow
\infty$), we prove that the curve of one-way deficit versus $p$ approaches to a
straight line with slope $1$. We also calculate the Holevo quantity for the
generalized $n$-qubit Werner state, and show that it is zero.
