demonstration of quantum cryptography 🐈 🔐 , one-time pad communication via BB84. repo for our IT Security Master project

The security of our critical infrastructure is threatened by the advent of future quantum computers, breaking asymmetric cryptography – an essential part of our secure communication architecture. Quantum key distribution (QKD) remedies this weakness by providing a long term secure solution, safe against attacks from quantum computers.

The aim is to allow Alice and Bob to generate a secure private key that can be used for the one-time pad without having to meet privately.

This repo consists of a python demonstration of the BB84 protocol of Quantum Key Distribution.

Python code to compute optimal protocol parameters for different QKD protocols.

Possible implementation of BB84 protocol using Simulaqron

My assignment solutions for Quantum Computing Workshop

The model of the quantum key exchange protocol BB84, implemented with high-level programming language Silq

Simulation of the BB84-protocol

Simulation of the BB84 Protocol

A simulation of the BB84 protocol in a Jupyter Notebook using the code from https://qiskit.org/textbook/ch-algorithms/quantum-key-distribution.html. Protocol steps until key sifting have been implemented. Error correction & parameter estimation were not executed.

Can we send information to the past or future, and due to entanglement past and present are same instance, Quantum delayed choice experiment - already proven impossible - however, personal rework and conceptual understanding

Project done on Jovian, as Jupyter won't easily work on github
