    "abstract": "It is shown that by switching a specific time-dependent interaction between a\nharmonic oscillator and a transmission line (a waveguide, an optical fiber,\netc.) the quantum state of the oscillator can be transferred into that of\nanother oscillator coupled to the distant other end of the line, with a\nfidelity that is independent of the initial state of both oscillators. For a\ntransfer time $T$, the fidelity approaches 1 exponentially in $\\gamma T$ where\n$\\gamma$ is a characteristic damping rate. Hence, a good fidelity is achieved\neven for a transfer time of a few damping times. Some implementations are\ndiscussed.",
