    "abstract": "Suppose we are given an entangled pair and then one can ask how well we can\nproduce two entangled pairs starting from a given entangled pair using only\nlocal operations. To give response of the above asked question, we study\nbroadcasting of entanglement using state dependent quantum cloning machine as a\nlocal copier. We show that the length of the interval for\nprobability-amplitude-squared for broadcasting of entanglement using state\ndependent cloner can be made larger than the length of the interval for\nprobability-amplitude-squared for broadcasting entanglement using state\nindependent cloner. Further we show that there exists local state dependent\ncloner which gives better quality copy (in terms of average fidelity) of an\nentangled pair than the local universal cloner.",
