Doctoral student in Physics within Microwave Quantum Optics and Detectors

Overview

Lund University was founded in 1666 and is repeatedly ranked among the world's top universities. The University has around 47 000 students and more than 8 800 staff based in Lund, Helsingborg and Malmö. We are united in our efforts to understand, explain and improve our world and the human condition. Lund University welcomes applicants with diverse backgrounds and experiences. We regard gender equality and diversity as a strength and an asset.

Description of the workplace

The research at the division of Solid State Physics within the Physics Department is focused around different aspects of nanophysics, ranging from materials science to quantum physics and different applications. The division plays a central role in NanoLund, the major interdisciplinary research environment within nanoscience and nanotechnology at Lund University, and it hosts Lund Nano Lab, a central key facility for fabrication of material and devices on the nanoscale. The division is also heavily involved in the undergraduate education, especially within the "Engineering Nanoscience" program. A significant part of the research at our division is in the area of semiconductor quantum devices, where we develop new methods and functionalities for quantum technology. Quantum technology is a new research direction that builds on the fundamental physical laws governing the microscopic world. It provides conceptually new capabilities with radical improvements, in terms of capacity, sensitivity and speed, of applications in a broad range of areas such as information processing, material science and electronics.

Work duties

The main duties of doctoral students are to devote themselves to their research studies which includes participating in research projects and third cycle courses. The work duties can also include teaching and other departmental duties (no more than 20%).

This specific position focuses on performing quantum optics experiments and aims to build photodetectors for microwave photons and gain access to the statistical properties of the photons. The microwave photons mediate coherent interactions as well as form the readout method for the main solid-state approaches to quantum technology ranging from superconducting qubits to spin qubits. As a PhD student in this position, you will get hands-on experience in quantum device fabrication in Lund Nano Lab, perform measurements on them and develop physics understanding of their operation. You will work as an important member of our research team in collaboration with other research groups in Lund and other high-ranking international universities. The work provides a good mix of fundamental physics concepts and technology-oriented mindset to build new sensors.

Detailed description of the work duties, such as:

• Device fabrication in cleanroom environment in the Lund Nano Lab.
• Transport and high-frequency microwave measurements, including programming of measurement scripts.
• Analysis of the measurement results to gain understanding on their operation and to design new devices.
• Writing scientific publications

The purpose of the PhD project is to build a microwave photodetector and measure microwave signals and their statistics at the level of individual photons. In addition, the position may include development of various other optics type components in the microwave domain and fundamental studies of quantum measurements. The PhD student is expected to work independently as well as in close collaboration with the other partners in the project.

Admission requirements
