You are an expert in forward error correction and looking for a new opportunity? We are offering a research position for the development of highly efficient low-density parity check (LDPC) error correcting codes for new quantum communication systems with a prime focus on Continuous-Variable Quantum Communication and Cryptography.

The project will be hosted by the section for Quantum Physics and Information Technology (QPIT) at the Department of Physics, Technical University of Denmark (DTU) headed by Prof. Ulrik L. Andersen. An 18 month research stay at the Digital Safety & Security department at the Austrian Institute of Technology (AIT) will be part of the project.

The overarching vision of the project is to establish a secure quantum communication network in the city of Copenhagen based on continuous variable quantum key distribution. Within the project we will have a special focus on developing rugged, robust, high-efficiency and high rate systems compatible with field implementations. We are working towards the construction of device independent systems that are resilient against any potential device attacks. It is an interdisciplinary and innovative project that involves experts within cryptography, classical post processing, hardware development, fabrication and security analysis.

The project is part of Qubiz, Quantum Innovation Center (www.qubiz.dk), which is a joint Danish national center including DTU, Copenhagen University and Aarhus University with the mission to harness the very strong Danish research positions within quantum technology for creating new quantum technology businesses.

QPIT conducts widely recognized research within a range of diverse topics such as continuous-variable quantum information processing, quantum enhanced sensing, and engineering of solid state quantum systems.
The Digital Safety & Security department at the Austrian Institute of Technology has been developing quantum key distribution technology since 2002 and is a front-runner in post-processing software and error correction coding for quantum cryptographic systems.

Responsibilities and tasks
We are looking for a highly motivated candidate that will be in charge of developing, optimizing, implementing and testing error correction codes and algorithms for the AWGN channel with Gaussian modulation. The special challenge is the requirement for codes that work with a rate very close to capacity and a high decoding throughput over a channel with low SNR.

The work will be performed in tight collaboration with university researchers and industry partners.

Qualifications

  • Strong background in the design of sparse graph codes (low-density parity-check codes).
  • Expertise in efficient decoding algorithms.
  • Knowledge of C++, Python, OpenCL, VHDL will be considered a plus.
  • Candidates should have a PhD degree or equivalent.
We offer
We offer an interesting and challenging job in an international environment focusing on education, research, scientific advice and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world.

Salary and terms of employment
The appointment will be based on the collective agreement with the Confederation of Professional Associations. The allowance will be agreed with the relevant union.

Workplace and period of employment
The work will take place at the DTU campus in Lyngby and at the Austrian Institute of Technology in Vienna.

The period of employment is 3 years and will be offered as 2 + 1 year contracts. Further extension might be possible.

Further information
Informal inquiries can be made to Dr. Christoph Pacher (Christoph.Pacher@ait.ac.at), Assist. Prof. Tobias Gehring (tobias.gehring@fysik.dtu.dk) or Prof. Ulrik L. Andersen (ulrik.andersen@fysik.dtu.dk).

Application procedure
Please submit your online application no later than 15 March 2017.

Applications must be submitted as one PDF file containing all materials to be given consideration. To apply, please open the link "Apply online," fill in the online application form, and attach all your materials in English in one PDF file. The file must include:
  • Application (cover letter)
  • CV
  • Diploma (MSc/PhD)
  • List of publications
Applications and enclosures received after the deadline will not be considered.

All interested candidates irrespective of age, gender, disability, race, religion or ethnic background are encouraged to apply.

QPIT's vision is to understand, engineer and control complex quantum systems of light and matter, and to exploit these systems for quantum information processing and quantum metrology.

We are a large, highly international research group of students and staff with diverse backgrounds. We have a friendly and dynamic research environment with close, daily interaction among all group members and strong collaborations with many academic and industrial partners. Technical support is excellent with electronics and process engineers embedded in the section and a large capacity, skilled mechanical workshop at the Department.

We are situated just north of Copenhagen at the Lyngby campus of DTU, one of the leading technical universities of Northern Europe, where we enjoy newly renovated office and lab space.

DTU is a technical university providing internationally leading research, education, innovation and scientific advice. Our staff of 5,800 advance science and technology to create innovative solutions that meet the demands of society; and our 10,600 students are being educated to address the technological challenges of the future. DTU is an independent academic university collaborating globally with business, industry, government, and public agencies.
