Project description
The main goal of the project is implementing the E91 Quantum Key Distribution protocol in a simulated environment, and studying the effects the different noise implementations of the Qiskit and QuantumSim simulators.
Context
Real quantum devices suffer from quantum noise. Simulators employ noise models to simulate noise, allowing researchers to study the effects noise have on various quantum programs, such as the E91 Quantum Key Distribution protocol.
Results
Under ideal conditions both Qiskit and QuantumSim show expected CHSH inequality values, with the cases where an eavesdropper is present showing values below 2, successfully signaling the presence of the eavesdropper.
Under noisy conditions, with the noise parameters applied, the protocol remains functional, however differences arise, with QuantumSim showing higher noise levels, this difference is more pronounced when an eavesdropper is introduced.
