    "abstract": "Very recently, it was shown by Ghosh, Kar, Roy and Sen (\\emph{Entanglement\nvs. Noncommutativity in Teleportation}, quant-ph/0010012) that if it is \\emph{a\npriori} known that the state to be teleported is from a commuting set of\nqubits, a separable channel is sufficient. We show that 1 ebit of entanglement\nis a necessary resource to teleport a qubit even when it is known to be one of\ntwo noncommuting states.",
