Non-maximally entangled mixed states of X and non-X types as teleportation channels
Anushree Pandey, Sovik Roy, Md. Manirul Ali +1
Mixed spin-1/2 states violating Bell-CHSH inequality is useful for teleportation. There exist states which do not violate Bell-inequality but is still useful as teleportation chann…
Exploring quantum properties of bipartite mixed states under coherent and incoherent basis
Sovik Roy, Anushree Bhattacharjee, Chandrashekar Radhakrishnan +2
Quantum coherence and quantum entanglement are two different manifestations of the superposition principle. In this article we show that the right choice of basis to be used to est…
Unitary and non-unitary operators leverage perfect and imperfect single qutrit teleportation
Sovik Roy, Anushree Pandey, Tushar Kanti Dey +1
Teleportation, a novel scheme, initially posited by Bennett \textit{et.al}, has been studied here in the context of sending a single qutrit from Alice to Bob using two qutrit entan…
Teleportation of unknown qubit via Star type tripartite states
Anushree Pandey, Abhijit Mandal, Sovik Roy
Eylee Jung \textit{et.al}\cite{jung2008} had conjectured that is a necessary and sufficient condition for the perfect two-party teleportation and consequently…
Quantum Teleportation of a Single Qutrit using Two-Qutrit Entangled States
Surajit Sen, Tushar Kanti Dey, Anushree Bhattacharjee +1
We demonstrate quantum teleportation of a qutrit system using a complete set of two-qutrit entangled states obtained from the representation theory of the SU(3) group. All measurem…
