Abstract
We study one-way quantum deficit of two-qubit states systematically from analytical derivations. An effective approach to compute one-way quantum deficit of two-qubit states has been provided. Analytical results are presented as for detailed examples. Moreover, we demonstrate the decoherence of one-way quantum deficit under phase damping channel.
