Job Description

You are passionate about working at the absolute forefront of technology? Here is the opportunity for you to fulfil your ambitions!
Continuous-variable quantum key distribution (CV-QKD) offers unique advantages for the distribution of secret keys between two parties for data encryption. Utilizing components similar to standard telecom components makes it an attractive solution for cost-effective and high-performance metropolitan applications. The technology exhibits significant parallels with coherent optical telecommunication. However, noise is absolute crucial as it is attributed to an eavesdropper, therefore presenting exciting challenges and opportunities. 
Within this position you will advance digital-signal-processing techniques for coherent and squeezed state CV-QKD by developing new algorithms and by evaluating them in simulations and in experiments.
The position will be hosted by the Section of Quantum Physics and Information Technology (QPIT) at the Department of Physics of the Technical University of Denmark (DTU). We are a dynamic, innovative and diverse research team focused on all aspects of CV-QKD. Our team is passionate about advancing secure communication methods based on quantum physics and bringing quantum key distribution to the people. We have a wide range of academic and industry collaborations, e.g. as part of the EU Flagship on quantum technology and the European Quantum Communication Infrastructure.
Responsibilities and qualifications
We are looking for a highly motivated candidate who will conduct research in advanced digital-signal-processing techniques for continuous-variable quantum key distribution by developing new algorithms and performing experimental evaluation. You will:

• conduct research on digital-signal-processing algorithms towards high-speed CV-QKD
• develop new methods for e.g. clock and phase recovery that support real-time high-speed implementations.
• use machine learning to improve discrete modulation formats.
• develop MATLAB or python code.
• experimentally demonstrate the developed algorithms and methods to evaluate their performance.

You have a passion for digital-signal-processing algorithms for coherent telecommunication systems and you are intrigued by its application in continuous-variable quantum key distribution. You enjoy finding clever solutions to difficult problems and further you have the following qualifications:

• Experience with modern digital-signal-processing techniques for optical telecommunication or continuous-variable quantum key distribution, e.g. matched-filtering, phase recovery, clock recovery, polarization equalization, etc.
• Experience with python or MATLAB programming.
• Experience with version control systems (git)
• Experience with fiber optic setups.
• You thrive by working in a diverse and multidisciplinary team of people. 

As a formal qualification, you must hold a PhD degree (or equivalent). 
We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation, and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility. 
Salary and terms of employment
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union. The period of employment is 2 years.
