Two Party Non-Local Games
Indranil Chakrabarty, B. S. Choudhury
In this work we have introduced two party games with respective winning conditions. One cannot win these games deterministically in the classical world if they are not allowed to c…
Boltzmann-Shannon Entropy: Generalization and Application
C. G. Chakrabarti, Indranil Chakrabarty
The paper deals with the generalization of both Boltzmann entropy and distribution in the light of most-probable interpretation of statistical equilibrium. The statistical analysis…
Probabilistic exact deletion and probabilistic no-signalling
Indranil Chakrabarty, Satyabrata Adhikari, B. S. Choudhury
In this work we show that one cannot use non-local resources for probabilistic signalling even if one can delete a quantum state with the help of probabilistic quantum deletion mac…
Broadcasting of three qubit entanglement via local copying and entanglement swapping
Satyabrata Adhikari, B. S. Choudhury
In this work,We investigate the problem of secretly broadcasting of three-qubit entangled state between two distant partners. The interesting feature of this problem is that starti…
Improving the Fidelity of deletion
Satyabrata Adhikari, B. S. Choudhury
In this work we study the quantum deletion machine with two transformers and show that the deletion machine with single transformer performs better than the deletion machine with m…
Revisiting impossible quantum operations using principle of no-signalling and non increase of entanglement under LOCC
Indranil Chakrabarty, Satyabrata Adhikari, B. S. Choudhury
In this letter, we show the impossibility of the general operation introduced by Pati [3] using two different but consistent principles (i) no-signalling (ii) non increase of entan…
