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.

量子力学是我们最强大的自然理论之一，它以令人难以置信的准确性在微观尺度上描述我们的世界。我们的量子力学知识使人类能够开发出强大的技术，例如激光、计算机和智能手机中的电子硅芯片，并使我们对宇宙的基本运作有了深刻的了解。该奖学金旨在通过激光和高频机械振动进行实验来加深我们对量子力学的理解和控制。范纳博士和他的团队成员将使用激光制备一个“同时”上下移动的量子叠加机械振荡器。这种类型的运动是臭名昭著的“薛定谔的猫”思想实验的实现。通过实证研究这种状态的动力学将使我们能够阐明量子世界和经典世界之间的基本机制。此外，该项目中开发的技术和获得的新知识将用于开发强大的新型量子物理增强技术，用于未来的信息处理应用。
