QKD System Simulation Software
Product Overview
The QKD system simulation software (QKD Simulator, or Qsim) is a tool designed for engineering education related to quantum key distribution. With Qsim, we can perfectly address the contradiction between the large-scale engineering education demands in quantum communication and the high costs and difficulty of scaling up physical quantum information systems. At the same time, Qsim helps shorten teaching time—by simply dragging and dropping components and connecting them, users can easily set up any optical experiment and obtain accurate results.
