摘要:
Large objects, consisting of trillions of atoms, should adhere to the laws of quantum mechanics just like single atoms, photons, etc. One of the consequences is that they exhibit quantum motion – at the scale of femtometers for a typical nanomechanical oscillator. This scale also sets the fundamental limit to the precision of a position measurement. In this project, you will use advanced optical techniques to perform measurements at this limit, and even break it. In doing so, we will in fact gain control over the quantum state of motion of the object. For this purpose, we develop novel nanophotonic structures that show very strong coupling between light and mechanical motion, and study entirely new ways to couple light to and from the systems. You will take a leading role in a small team to establish such quantum measurement and control of a nanomechanical oscillator, and be involved in all aspects of design, realization, and cryogenic optical measurements in order to demonstrate new ways to manipulate the quantum state of large objects. Research In this project, we will use advanced nanophotonic systems to perform quantum measurements on the position of nanomechanical oscillators. Through such measurements, we seek to control the quantum state of a 'macroscopic' object.
