    "abstract": "Unmeasureability of a quantum state has important consequences in practical\nimplementation of quantum computers. Like copying, deleting of an unknown state\nfrom among several copies is prohibited. This is called no-deletion prinicple.\nHere, we present a no deleting principle for qudits. We obtain a bound on\n$N$-to-$M$ deleting and show that the quality of deletion drops exponentially\nwith the number of copies to be deleted. In addition, we investigate\nconditional, state-dependent and approximate quantum deleting of unknown\nstates. We prove that unitarity does not allow us to delete copies from an\nalphabet of two non-orthogonal states exactly. Further, we show that\nno-deleting principle is consistent with no-signalling.",
