Postdoc in Machine Learning for Quantum Key Distribution – DTU Electro

Company:

Danmarks Tekniske Universitet

Job description

Job Description:DTU Electro invites applications for a position as a postdoctoral researcher in machine learning enabled continues variable quantum key distribution within the Innovation Fund Denmark program “Advancing cybersecurity with continuous variable quantum cryptography (CyberQ). The position is focused on developing machine learning frameworks, in terms of pulse-shaping, as well as phase noise mitigating for maximizing secure key rate transmission through a fiber-optic channel.The focus will be on energy-efficient solutions.We seek a motivated, curious, and outgoing PhD candidate with a solid background in fiber-optics, communication engineering and machine learning. Experience with application of machine learning to communication systems and experimental work is a plus.The project goal is to develop robust transmitter and receiver architectures that can enable distortion-free secret key rate transmission. The project will cover both algorithm development as well as experimental implementations.We offer an opportunity to develop expertise in various domains, including but not limited to:

• Machine learning techniques for design of CV-QKD fiber-optic communication systems
• Development of physical system models and data driven model
• Realization of experimental procedures for test of the developed frameworks
• Building CV-QKD transmission systems
• Investigating transmission performance in practical test-beds

Responsibilities and qualifications
Your tasks will include research into novel machine learning based methods for mitigation of impairments associated with using an optical fibre as a transmission medium. More specifically, the focus will be on minimizing transmitter-receiver induced distortions. The overall goal will be to maximize the secure key rate and the transmission distance given the energy-consumption constraint. Specifically, you will focus on the following areas:

• Gradient based learning for signal symbol and pulse shaping
• Model-free reinforcement learning signal pre-distortion strategies
• Extracting the relevant information from correlation matrices
• Maintenance of the GitHub repository for the developed code
• Organizing and managing joint experiments with the collaboration groups

As a formal qualification, you must hold a PhD degree (or equivalent). Eligible candidates should have a PhD degree in telecommunication or photonics engineering. Ability to work independently, to plan and carry out complicated task, as well as excellent communication skills in English, both written and spoken, are highly desired.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.
