Query: Composable security for continuous variable quantum key distribution:
  Trust levels and practical key rates in wired and wireless networks   Continuous variable (CV) quantum key distribution (QKD) provides a powerful
setting for secure quantum communications, thanks to the use of
room-temperature off-the-shelf optical devices and the potential to reach much
higher rates than the standard discrete-variable counterpart. In this work, we
provide a general framework for studying the composable finite-size security of
CV-QKD with Gaussian-modulated coherent-state protocols under various levels of
trust for the loss and noise experienced by the parties. Our study considers
both wired (i.e., fiber-based) and wireless (i.e., free-space) quantum
communications. In the latter case, we show that high key rates are achievable
for short-range optical wireless (LiFi) in secure quantum networks with both
fixed and mobile devices. Finally, we extend our investigation to microwave
wireless (WiFi) discussing security and feasibility of CV-QKD for very
short-range applications.
