Quantum simulators permit the study of quantum systems that are difficult to study in the laboratory and impossible to model with a supercomputer. In this instance, simulators are special purpose devices designed to provide insight about specific physics problems.[1][2][3] Quantum simulators may be contrasted with generally programmable "digital" quantum computers, which would be capable of solving a wider class of quantum problems.
QKD simulator © is a web application aimed at simulating and analyzing Quantum Key Distribution protocols. The online simulator is powered by the QKD Simulation Toolkit, which is capable of customizing a wide range of parameters for individual components and sub-protocols in the system, e.g., Quantum channel, Sifting, Error estimation, Reconciliation, Privacy Amplification. Each simulation provides detailed information about the intermediate and final stages of the protocol.
