    "abstract": "In $2 \\otimes 2$, more than 2 orthogonal Bell states with single copy can\nnever be discriminated with certainty if only local operations and classical\ncommunication (LOCC) are allowed. More than $d$ orthogonal maximally entangled\nstates in $d \\otimed d$, which are in cannonical form, used by Bennett et. al.\n[Phys. Rev. Lett. 70 (1993) 1895] can never be discriminated with certainty\nwhen a single copy of the states is provided. Interestingly we show that all\northogonal maximally entangled states, which are in cannonical form, can be\ndiscriminated with certainty if and only if two copies of each of the states\nare provided. The highly nontrivial problem of local discrimination of $d$ or\nless no. of pairwise orthogonal maximally entangled states in $d \\otimes d$ (in\nsingle copy case), which are in cannonical form, is also discussed.",
