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.
