Disentanglement in qubit-qutrit systems
Mazhar Ali, A. R. P. Rau, Kedar Ranade
We examine the phenomenon of {\it entanglement sudden death} (ESD) for -dimensional systems. As for systems, the negativity vanishes in finite time for s…

The Jamiołkowski isomorphism and a conceptionally simple proof for the correspondence between vectors having Schmidt number and -positive maps
Kedar S. Ranade, Mazhar Ali
Positive maps which are not completely positive are used in quantum information theory as witnesses for convex sets of states, in particular as entanglement witnesses and more gene…

Asymptotic correctability of Bell-diagonal quantum states and maximum tolerable bit error rates
Kedar S. Ranade, Gernot Alber
The general conditions are discussed which quantum state purification protocols have to fulfill in order to be capable of purifying Bell-diagonal qubit-pair states, provided they c…
