    "abstract": "We propose entangled (M+1)-mode quantum states as a multiuser quantum channel\nfor continuous-variable communication. Arbitrary quantum states can be sent via\nthis channel simultaneously to M remote and separated locations with equal\nminimum excess noise in each output mode. For a set of coherent-state inputs,\nthe channel realizes optimum symmetric 1-to-M cloning at a distance\n(``telecloning\u0027\u0027). It also provides the optimal cloning of coherent states\nwithout the need of amplifying the state of interest. The generation of the\nmultiuser quantum channel requires no more than two\n10\\log_{10}[(\\sqrt{M}-1)/(\\sqrt{M}+1)] dB squeezed states and M beam splitters.",
