Quantum Cryptography - 100 percent secure communication

Location

Greater Copenhagen area

The aim of this project is to build an experimental setup for EPR-Quantum Key Distribution to demonstrate 100% communication

Can we use quantum mechanics to achieve communication 100% secure against eavesdropping? In this project, you will develop an experimental setup to send encrypted messages using EPR Quantum Key Distribution. We have a source of entangled photons (EPR states) and we would like to use these to establish a secure communication between two points (Alice and Bob). In order to do this, the concept of quantum key distribution and quantum mechanics are used to ensure the sharing of a secret key between Alice and Bob. Multiple existing protocols will be studied and one of them will be chosen for implementation in our lab, starting from scratch.

Goals of the project (which may be modified according to the interests of the student)

• understanding pro and cons of different EPR-QKD protocols for implementation in our lab

• design and build a robust setup for the chosen protocol, starting from our EPR source

• demonstrate EPR-100% secure communication for the first time at DTU Fotonik 

Requirements

Knowledge of quantum mechanics (e.g. from 10112 Advanced Quantum Mechanics)

Technical University of Denmark

For almost two centuries DTU, Technical University of Denmark, has been dedicated to fulfilling the vision of H.C. Ørsted – the father of electromagnetism – who founded the university in 1829 to develop and create value using the natural sciences and the technical sciences to benefit society.


Today, DTU is ranked as one of the foremost technical universities in Europe, continues to set new records in the number of publications, and persistently increases and develops our partnerships with industry, and assignments accomplished by DTU’s public sector consultancy.
