The author found a mistake in his published article that somehow crept in after the author corrected proofs.

In page-3 of the published article, the last line of the first paragraph from bottom of the page and the second paragraph from bottom of the page should be modified as shown in Table below:

In Page-3

In second Para from bottom of the Page-3

The combined state of the qubits a, δ, A1, B1, B2 is

The combined state of the qubits a, δ, A1, A2, B1, B2 is given in Eq. (6) in which |Ψ±⟩| and |ϕ±⟩ are four Bell-states given by \( \left|\left.{\varPsi}^{\pm}\right\rangle =\frac{1}{\sqrt{2}}\left[\left|\left.00\right\rangle \pm \left|11\right\rangle \right.\right]\right., \) \( \left|\left.{\phi}^{\pm}\right\rangle =\frac{1}{\sqrt{2}}\left[\left|\left.01\right\rangle \pm \left|10\right\rangle \right.\right].\right. \)

 

Here \( \left|\left.{\phi}^{\pm}\right\rangle =\frac{1}{\sqrt{2}}\left[\left|\left.00\right\rangle \pm \right|\left.11\right\rangle \right]\right|\mathrm{and} \) \( \left|\left.{\varphi}^{\pm}\right\rangle =\frac{1}{\sqrt{2}}\left[\left|\left.01\right\rangle \pm \right|\left.10\right\rangle \right]\right| \) are four Bell-state.
