Summer work as a project assistant in quantum technology - Hiring in process/Finished, not possible to apply

Description of the workplace 
The work place are the divisions of Solid state physics and Atomic Physics, Physics department. Information about the divisions can be found at the respective division webpages, https://www.ftf.lth.se/ and https://www.atomic.physics.lu.se/

We offer
Lund University is a public authority which means that employees get particular benefits, generous annual leave and an advantageous occupational pension scheme. Read more on the University website about being a Lund University employee Work at Lund University. The summer work positions are financed by the Marcus and Amalia Wallenberg foundation through EDU-WACQT, an initiative for strengthening Swedish undergraduate education in Quantum Technology.

Work duties 
The work duties will be to perform research within the field of Quantum technology, with the focus of the work determined by the specific project topic.

There are three possible projects available, described briefly below.

1. Microwave resonator circuits. Contact person: Ville Maisi. Our research group studies experimentally solid-state quantum devices. We focus on devices where microwave photons and electrons in semiconductor quantum dots interact coherently. The summer work project provides a unique opportunity to work with microwave resonators hosting the photons. You will be working together with the researchers in the group to make resonators that show non-linearities already with a few photons, a functionality that enables new device concepts. We will aim to demonstrate this by observing the resonance frequency changing considerably already after adding the very first photon into the resonator. The project offers you to see and get hands-on experience over a wide range of nanophysics area: from device fabrication in the cleanroom, to electrical measurements at low temperatures, and theory concepts to understand the device operation.
   
   
2. Machine learning for ultrafast quantum state tomography of photoelectrons. Contact person: David Busto. The project aims at measuring at the quantum state of photoelectrons emitted from the interaction of attosecond extreme ultraviolet pulses with matter. More specifically, a Bayesian optimization algorithm will be developed in order to extract the reduced photoelectron density matrix from a series of photoelectron interferograms. The algorithm will be first optimized using simulated data before applying it experimental data. This project lies at the interface of attosecond physics and quantum information science.
   
   
3. Machine learning for quantum devices. Contact person: Martin Leijnse. In this project you will develop and use machine learning (ML) methods to interpret measurement data from quantum devices, with the long-term goal of automating device tuning and calibration. The focus will be on spin qubits in semiconductor quantum dots. In such qubit systems, one needs to finetune the properties of, and couplings between, a large number of quantum dots. This is a very time-consuming task and becomes unmanageable when scaling to the large numbers of qubits needed for practical quantum computing. Our goal in this project is to take the first steps towards automating this finetuning process.

In the research group we have extensive experience from the theory of quantum dots, quantum transport and spin qubits.

Qualifications
Required qualifications for the position are:

• Ongoing Swedish university education in physics or another subject relevant for the project, at bachelor, master or equivalent level.
• Very good knowledge of English, both spoken and written, is a requirement.

Additional qualifications for the position are:

• Knowledge about the specific topic of the project applied for is considered a merit.
• Consideration will be given to good collaborative skills, drive and independence.

Further information 
Fixed term employment for 2,5-5 months on 50-100%, during the summer 2023. Starting date and scope is decided in agreement with the project contact person. 

How to apply
Applications are to be submitted via the University’s recruitment system. The application should include a CV and a personal letter justifying your interest in the position and how it matches your qualifications. Please specify which of the three project you apply for, and if more than one, provide an order of priority. The application should also include a degree certificates or equivalent and any other document to which you would like to draw attention (copies of grade transcripts, details of referees, letters of recommendation, etc.)”
