Power Consumption Analysis of QKD Networks under Different Protocols and Detector Configurations

We analyze the power consumption of quantum key distribution (QKD) networks under various protocol and detector configurations. Using realistic network topologies, we evaluate discrete-variable vs continuous-variable QKD and optimize device placement, quantifying power trade-offs of SNSPD vs APD detectors and the benefits of optical bypass.

Abstract

We analyze the power consumption of quantum key distribution (QKD) networks under various protocol and detector configurations. Using realistic network topologies, we evaluate discrete-variable vs continuous-variable QKD and optimize device placement, quantifying power trade-offs of SNSPD vs APD detectors and the benefits of optical bypass.
