Partial K-way negativities and three tangle for three qubit states
S. Shelly Sharma, N. K. Sharma
We obtain, analytically, the global negativity, partial way negativities (K=2, 3), Wooter's tangle and three tangle for the generic three qubit canonical state. It is found tha…

Multipartite entanglement of three trapped ions in a cavity and W- State generation
S. Shelly Sharma, Eduardo de Almeida, Naresh K. Sharma
A scheme to generate three qubit maximally entangled W-states, using three trapped ions interacting with red sideband tuned single mode field of a high finesse cavity, is proposed.…

Quantum mutual entropy for two-level ion in a q-analog trap
S. Shelly Sharma, N. K. Sharma
Quantum mutual entropy is used as a measure of information content of ionic state due to ion-laser interaction in a q-analog trap. The initial state of the system is a Schrodinger…
