Aalto University

Doctoral Candidate in Quantum Nanomechanics

Aalto University

Espoo, Finland

The Quantum Nanomechanics group http://physics.aalto.fi/en/groups/nems/ at the Department of Applied Physics, Aalto University http://www.aalto.fi/en/, Finland, is looking for an outstanding

DOCTORAL CANDIDATE

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
In his/her project, the DOCTORAL CANDIDATE will realize a prototype quantum information link using the entangled aluminum drumhead resonators. You will accommodate these devices into a quantum-limited detection system comprising of parametric amplifiers and real-time feedback, in order to demonstrate quantum teleportation or remote state preparation in the electromechanical system. The work involves sample design via electromagnetic simulations, cleanroom fabrication, running of the measurements, and data analysis. At the beginning, the candidate will work together with other group members, both in the cleanroom and with the measurements. Over time, the candidate is expected to gain responsibility of the experimental part. We require the candidates to have experience either in cryogenic measurements, or clean room techniques and e-beam lithography.
