Postdoctoral Researcher in Quantum Nanomechanics
Application closes on
to experimentally work on electromechanical quantum systems. The work is funded by the European Commission under the FET Proactive project Hybrid Optomechanical Technologies (HOT), by the ERC under the project CAVITYQPD, and by the Academy of Finland.
The position is filled and the work can start as soon as suitable candidate is found, but no later than by the end of 2019.
The research of our ambitious team is focused on fundamental research on the quantum-mechanical properties of micromechanical systems. We use microwave optomechanics based on superconducting microwave cavities and micromechanical resonators made with aluminum or silicon nitride membranes. In our recent work, we demonstrated quantum entanglement between two aluminum resonators [Nature 556, 478 (2018)]. With superconducting qubits, we explore the resonant conversion of quantum information and mechanical motion. In longer term, we are interested in the role of gravitation in quantum micromechanics, and in using levitated nanoparticles as quantum systems.
Our more applied research, as a part of the HOT consortium, will lay the foundation for a new generation of devices that use various types of optomechanical effects for efficient signal processing. We have realized quantum-limited microwave amplifiers and nonreciprocal components to be used in superconducting quantum technology. Besides electromechanics, we are building hybrid devices that aim on controlling ferromagnetic magnons using acoustic waves for signal processing.
Main tasks and requirements
The POSTDOCTORAL RESEARCHER will be responsible for the development and measurement of microwave optomechanical quantum chips, where the core element is a silicon nitride membrane that at very low temperatures becomes nearly isolated from energy losses to the environment. You will accommodate these devices into a quantum-limited detection system comprising of parametric amplifiers and real-time feedback, in order to create non-classical states in novel ways.
For this challenging research, we are looking for outstanding candidates who are motivated in experimental, low-temperature solid state physics. We require the candidates to have a proven track record in quantum nanophysics, clean room techniques, and strong interest in micromechanical systems. In addition, the candidates should have experience in running measurements in modern cryogenic systems.
