Quantum mechanics is one of our most powerful theories of nature and describes our world on the microscopic scale with incredible accuracy. Our knowledge of quantum mechanics has enabled humanity to develop powerful technologies such as the laser, electronic silicon chips in computers and smartphones, and has given us great insight into the fundamental workings of the universe. This fellowship aims to deepen our understanding and control of quantum mechanics by conducting experiments with lasers and high frequency mechanical vibrations. Dr Vanner and the members of his team will use lasers to prepare a mechanical oscillator in a quantum superposition of moving up and down 'at the same time'. This type of motion is then a realization of the infamous 'Schrodinger's cat' thought experiment. Empirically studying the dynamics of this state will enable us to shed much needed light on the fundamental mechanisms at the divide between the quantum and classical worlds. Moreover, the techniques developed, and the new knowledge gained within this project, will be utilized to develop powerful new quantum-physics-enhanced technologies for the information processing applications of the future.
