Quantum Technologies

The Focus Group around Professor Menno Poot concentrates on Quantum Technologies. It makes chips using state-of-the-art nanofabrication techniques to study quantum effects in a variety of systems. For example, the Focus Group looks at nanomechanical resonators at millikelvin temperatures, where these are in their quantum groundstate. Yet their tiny zero-point motion can be measured using ultra-sensitive optomechanical techniques. Another important topic is integrated quantum optics, where photonic chips with functionality to generate, manipulate, and detect single photons are designed, made, and measured.
