    "abstract": "The ultimate limits of continuous-variable single-mode quantum teleportation\ndue to absorption are studied, with special emphasis on (quasi-)monochromatic\noptical fields propagating through fibers. It is shown that even if an\ninfinitely squeezed two-mode squeezed vacuum were used, the amount of\ninformation that would be transferred quantum mechanically over a finite\ndistance is limited and effectively approaches to zero on a length scale that\nis much shorter than the (classical) absorption length. Only for short\ndistances the state-dependent teleportation fidelity can be close to unity. To\nrealize the largest possibly fidelity, an asymmetrical equipment must be used,\nwhere the source of the two-mode squeezed vacuum is nearer to Alice than to Bob\nand in consequence the coherent displacement performed by Bob cannot be chosen\nindependently of the transmission lengths.",
