标题： Satellite Quantum Communication via the Alphasat Laser Communication Terminal

摘要： 通过利用量子效应，我们现在可以使用在原则上经证明能够抵御任何可想象攻击的加密方法。 这些迷人的量子特性已在世界各地的城市量子网络中得到实现。 为了在长距离上连接此类网络，光学卫星通信是首选方法。 标准电信组件可以使通过测量场分量（连续变量）高效地实现量子通信。 这使得我们能够将激光通信终端（LCTs）适应量子密钥分发（QKD）。 首批卫星测量活动目前正在验证我们的方法。 显示英文摘要

摘要： By harnessing quantum effects, we nowadays can use encryption that is in principle proven to withstand any conceivable attack. These fascinating quantum features have been implemented in metropolitan quantum networks around the world. In order to interconnect such networks over long distances, optical satellite communication is the method of choice. Standard telecommunication components allow one to efficiently implement quantum communication by measuring field quadratures (continuous variables). This opens the possibility to adapt our Laser Communication Terminals (LCTs) to quantum key distribution (QKD). First satellite measurement campaigns are currently validating our approach.
