Monogamous nature of symmetric N-qubit states of the W-class: Concurrence and Negativity Tangle
P. J. Geetha, K. O. Yashodamma, Sudha
Using Majorana representation of symmetric N-qubit pure states, we have examined the monogamous nature of the family of states with two-distinct spinors, the W-class of states. We…
Effectiveness of Depolarizing noise in causing sudden death of entanglement
K. O. Yashodamma, P. J. Geetha, Sudha
Continuing on the recent observation that sudden death of entanglement can occur even when a single qubit of a two qubit state is exposed to noisy environment, we examine the local…
Purification and redistribution of entanglement via single local filtering
K. O. Yashodamma, P. J. Geetha, Sudha
The effect of filtering operation with respect to purification and concentration of entanglement in quantum states are discussed in this paper. It is shown, through examples, that…
Is composite noise necessary for sudden death of entanglement?
K. O. Yashodamma, Sudha
The finite time disentanglement or entanglement sudden death, when only one part of the composite system is subjected to a single noise, is examined. While it is shown that entangl…
