Probabilistic Secret Sharing Through Noisy Quantum Channels
Satyabrata Adhikari, Indranil Chakrabarty, Pankaj Agrawal
In a realistic situation, the secret sharing of classical or quantum information will involve the transmission of this information through noisy channels. We consider a three qubit…
Quantum Dissension: Generalizing Quantum Discord for Three-Qubit States
Indranil Chakrabarty, Pankaj Agrawal, Arun K. Pati
We introduce the notion of quantum dissension for a three-qubit system as a measure of quantum correlations. We use three equivalent expressions of three-variable mutual informatio…
Purification of Mixed State with Closed Timelike Curve is not Possible
Arun K. Pati, Indranil Chakrabarty, Pankaj Agrawal
In ordinary quantum theory any mixed state can be purified in an enlarged Hilbert space by bringing an ancillary system. The purified state does not depend on the state of any extr…
