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…
Stronger no-cloning, no-signalling and conservation of quantum information
Indranil Chakrabarty, A. K. Pati, Satyabrata Adhikari
It is known that the stronger no-cloning theorem and the no-deleting theorem taken together provide the permanence property of quantum information. Also, it is known that the viola…
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…
Inseparability of Quantum Parameters
Indranil Chakrabarty, S. Adhikari, Prashant +1
In this work, we show that 'splitting of quantum information' [6] is an impossible task from three different but consistent principles of unitarity of Quantum Mechanics, no-signall…
