PhD position in Scalable Control of Cryogenic Quantum Photonics Experiments (SCOPE)

Ref LiU-2022-04797

Skilled and committed employees are a crucial factor in the success of Linköping University. And we need more of them. Our core expertise comes from teachers and researchers, but a successful university requires experienced and motivated employees in many fields. Everyone is important. We need to recruit many new employees thanks to, among all, an expansion in our research activity. We need you here. We look forward to receiving your application! The department of Electrical Engineering (ISY) is central to the engineering education at the Institute of Technology, one of four faculties at Linköping University, and this regards both basic and applied knowledge. The research is based on industrial needs, and ranges from basic research to direct application in collaboration projects. Read more at

We are looking for a PhD student in Scalable Control of Cryogenic Quantum Photonics Experiments (SCOPE).

Your work assignments Modern FPGAs such as the Xilinx RFSoC family integrate custom logic, programmable processors and high-performance analog functions and are excellent research vehicles to create the classical control of a cryogenic quantum engine.  In this research, we will consider quantum photonic devices and investigate the optimization of the control system to perform functions such as control signal generation, system reconfiguration and quantum state readout/evaluation. The optimization will focus on reducing latency and power dissipation to complete correction cycles faster than the qubit coherence times and minimize the thermal impact of the control system.  Possible techniques, previously investigated in our group, to reduce power include below-nominal voltage levels and selective power gating of the programmable logic. Initial experimentation will explore how deterministic single photon sources can be created via probabilistic photon multiplexing using interferometers with bidirectional couplers and electro-optical phase modulators controlled with FPGA-based multigigabit per-second digital-analog converters.

As a PhD student, you devote most of your time to doctoral studies and the research projects of which you are part. Your work may also include teaching or other departmental duties, up to a maximum of 20% of full-time.

Your workplace You will be employed in the Division for Computer Engineering that performs teaching and research on processor architectures and logic design. Please read more at

Your qualifications You have graduated at Master’s level in electrical or computer engineering, computer science or similar or completed courses with a minimum of 240 credits, at least 60 of which must be in advanced courses within the same topics. Alternatively, you have gained essentially corresponding knowledge in another way.

You are expected to meet the following requirements:

* Excellent programming skills in C++/Python

* Experience working with FPGA (i.e. Vitis, Zynq)

* Strong communication skills and knowledge in English

* Knowledge of quantum mechanics and optoelectronics is of value.

Terms of employment When taking up the post, you will be admitted to the program for doctoral studies. More information about the doctoral studies at each faculty is available at Doctoral studies at Linköping University

The employment has a duration of four years’ full-time equivalent. You will initially be employed for a period of one year. The employment will subsequently be renewed for periods of maximum duration two years, depending on your progress through the study plan. The employment may be extended up to a maximum of five years, based on the amount of teaching and departmental duties you have carried out. Further extensions can be granted in special circumstances.

Starting date By agreement.

Salary and employment benefits The salary of PhD students is determined according to a locally negotiated salary progression.

More information about employment benefits at Linköping University is available here.
