摘要
We show that an arbitrary relative phase can be extracted from a multiqubit two-component (MTC) entangled state by local Hadamard transformations and measurements along a single basis only. In addition, how to distinguish a MTC entangled state with an arbitrary entanglement degree and relative phase from a class of multiqubit mixed states is discussed.
