    "abstract": "In this paper we present an optimal protocol by which an unknown state on a\nHilbert space of dimension $N$ can be approximately stored in an\n$M$-dimensional quantum system or be approximately teleported via an\n$M$-dimensional quantum channel. The fidelity of our procedure is determined\nfor pure states as well as for mixed states and states which are entangled with\nauxiliary quantum systems of varying Hilbert space dimension, and it is\ncompared with theoretical results for the maximally achievable fidelity.",
