Quantum measurement of macroscopic objects

My present work is concerned with developing novel measurement techniques based on fundamentally quantum-mechanical principles. 

We examine quantum-mechanical transitions at an avoided crossing of energy levels in a generic system. The Landau-Zener model is taken as the starting point. We then probe the sensitivity of this set-up for experimental measurement of key physical quantities and compare it with other well-known techniques, such as Ramsey spectroscopy.

I am employed jointly by the University of Ulm and Imperial College, London. I am part of the Controlled Quantum Dynamics CQD, which provides me with dedicated lectures, exams to pass, transferable skills courses and ample opportunity for quantum bunching.
