BasejumpSIM by evolutionQ is a quantum-safe network simulator designed to model and simulate quantum key distribution (QKD) networks in a cloud environment. It allows users to simulate various aspects of a quantum delivery network, including QKD devices over fiber and QKD satellite links, without the need for physical QKD devices. BasejumpSIM enables the modeling of different network topologies, QKD link segments, and network traffic scenarios to approximate real operational environments.
