Separability in Asymmetric Phase-Covariant Cloning
A. T. Rezakhani, S. Siadatnejad, A. H. Ghaderi
Here, asymmetric phase-covariant quantum cloning machines are defined and trade-off between qualities of their outputs and its impact on entanglement properties of the outputs are…
On a suggestion relating topological and quantum mechanical entanglements
M. Asoudeh, V. Karimipour, L. Memarzadeh +1
We analyze a recent suggestion \cite{kauffman1,kauffman2} on a possible relation between topological and quantum mechanical entanglements. We show that a one to one correspondence…
Comment on "Dense coding in entangled states"
O. Akhavan, A. T. Rezakhani
In a recent Brief Report, Lee et al. [L. Lee, D. Ahn, and S.W. Hwang, Phys. Rev. A 66, 024304 (2002)] have claimed that using pairwise entangled qubits gives rise to an exponential…
Quantum dense coding by spatial state entanglement
O. Akhavan, A. T. Rezakhani, M. Golshani
We have presented a theoretical extended version of dense coding protocol using entangled position state of two particles shared between two parties. A representation of Bell state…
On The Relevance Of Fair Sampling Assumption In The Recent Bell Photonic Experiments
Afshin Shafiee, Mehdi Golshani
In the experimental verification of Bell's inequalities in real photonic experiments, it is generally believed that the so-called fair sampling assumption (which means that a small…
