Probabilistic cloning and signalling
Sibasish Ghosh, Guruprasad Kar, Samir Kunkri +1
We give a proof of impossibility of probabilistic exact cloning of any three different states of a qubit. The simplicity of the proof is due to the use of a surprising res…

Local cloning of Bell states and distillable entanglement
Sibasish Ghosh, Guruprasad Kar, Anirban Roy
The necessary and sufficient amount of entanglement required for cloning of orthogonal Bell states by local operation and classical communication is derived, and using this result,…
