msca doctoral network
Quantum Electrodynamics with Silicon Nanotechnology
QuEST: Educating tomorrow’s European researchers in silicon quantum electrodynamics at the deep nanoscale.
Explore the deep nanoscale
Recent breakthroughs have shown that silicon nanostructures with critical dimensions in the range of 1-10 nm - which we refer to as the deep nanoscale - are now accessible for the combination of optical, mechanical, and electronic physics experiments.
This forms the basis for the vision of QUEST: A highly ambitious research training program with the objectives to explore and exploit the confluence of optics, mechanics, and electronics at the deep nanoscale.
We will combine advanced numerical design with quantum theory to measure the mechanical forces resulting from quantum vacuum fluctuations, explore novel emitters and fast electron interactions to probe the properties of photonic cavities, develop new device concepts in optomechanics, and push the frontier of semiconductor material growth and fabrication nanotechnology.
Join the future of European quantum research
The QuEST doctoral network will design and fabricate optical nanocavities with extreme light confinement and embedded color centers for electronic interactions as well as designable vibrations and controllable tuning via electromechanical actuation.
In combination with advanced experimental techniques, we will leverage this material platform for next-generation quantum technology based on silicon quantum electrodynamics at the deep nanoscale.
This highly interdisciplinary and entrepreneurial undertaking brings together research groups from across Europe to educate a new generation of doctoral candidates in the full stack of skills needed in silicon quantum photonics technologies, including theory, modeling, design, material growth, nanofabrication, and a wide range of experimental techniques - as well as communication, collaboration, and leadership skills.
Build your future alongside 14 other PhD students in our highly collaborative network across Europe starting in the spring of 2027.
