    "abstract": "We show that the sender (Alice) and the receiver (Bob) each require coherent\ndevices in order to achieve unconditional continuous variable quantum\nteleportation (CVQT), and this requirement cannot be achieved with conventional\nlaser sources, even in principle. The appearance of successful CVQT in recent\nexperiments is due to interpreting the measurement record fallaciously in terms\nof one preferred ensemble (or decomposition) of the correct density matrix\ndescribing the state. Our analysis is unrelated to technical problems such as\nlaser phase drift or finite squeezing bandwidth.",
