Local Equivalence of Rank-Two Quantum Mixed States

Sergio Albeverio, Shao-Ming Fei, Debashish Goswami

We investigate the equivalence of quantum mixed states under local unitary transformations. For a class of rank-two mixed states, a sufficient and necessary condition of local equi…

Generalized Swanson models and their solutions

A. Sinha, P. Roy

We analyze a class of non-Hermitian quadratic Hamiltonians, which are of the form $H = A^{†} A + α A^{2} + β A^{† 2}$ , where $α, β$ are…

A complex periodic QES potential and exceptional points

B. Bagchi, C. Quesne, R. Roychoudhury

We show that the complex $P T$ -symmetric periodic potential $V (x) = - (i ξ sin 2 x + N)^{2}$ , where $ξ$ is real and $N$ is a positive integer, is quasi-exactly solvable. For…

Local cloning of genuine entangled states of three qubit

Sujit K. Choudhary, Guruprasad Kar, Samir Kunkri +2

We discuss (im)possibility of the exact cloning of orthogonal but genuinely entangled three qubit states aided with entangled ancila under local operation and classical communicati…

Local Cloning of Entangled Qubits

Sujit K. Choudhary, Samir Kunkri, Ramij Rahaman +1

We discuss the exact cloning of orthogonal but entangled qubits under local operations and classical communication. The amount of entanglement necessary in blank copy is obtained f…

A Geometrical Approach towards Entanglement

B. Basu, P. Bandyopadhyay

We have studied the concurrence of two-site entanglement and have shown that it is related to the geometric phase accumulated due to a complete rotation of the entangled state. The…
