- Abstract: Quantum key distribution (QKD) is an ingenious technology utilizing quantum
information science for provable secure communication. However, owing to the
technological limitations and device non-idealities it is important to analyze
the system performance critically and carefully define the implementation
security. With an acceleration in the commercial adoption of QKD, a simulation
toolkit is requisite to evaluate the functional architecture of QKD protocols.
We present a simulation framework to model optical and electrical components
for implementing a QKD protocol. The present toolkit aims to model and simulate
the optical path of the DPS-QKD protocol with its imperfections and eventually
characterize the optical path. The detailed device-level modeling and analysis
capabilities of the present toolkit based on Simulink and MATLAB have the
potential to provide universal toolkit for practical design and implementation
of generalized QKD protocols compared to earlier works. We report a novel work
on the implementation of a QKD protocol on Simulink and MATLAB platform.
Further, the absence of any modeling framework for DPS QKD and its simplistic
optical schematic made it an obvious choice for the authors. We are hopeful
that this work will pave way for simulating other QKD protocols from the DPR
family.
