    "abstract": "The amount of information transferred during standard quantum teleportation\nor remote state preparation is equal to the preparation information of the\ntransmitted state, rather than the classical communication required by\nrespective protocol. This is shown by noting that the information required to\nspecify the operation that verifies the transmitted state is identical to the\npreparation information, at the given level of precision m (in bits). Depending\non the resolution of the projective Hilbert space, the preparation information\ncan be made arbitrarily precise and hence indefinitely larger than the\nclassical communication cost. Therefore, the classical communication is\ninsufficient to account for the transfer of preparation information, which is\nthen attributed to the Einstein-Podolsky-Rosen channel. Some fundamental\nrepercussions for relativistic quantum information processing are briefly\ndiscussed.",
