attempts to design systems for quantum information processing, which promise to be exponentially more powerful than any possible classical computer. I will try to give a flavour about some of these perspectives, focussing largely on a particular paradigm known as "weak measurement."
Weak measurement is a natural extension of a pragmatic view of what it means to measure something about a quantum system, yet leads to some rather surprising results. I will describe a few examples of our recent experiments using weak measurement to probe fundamental issues in uantum mechanics such as what the minimum disturbance due to a quantum measurement is. I will also argue that there are regimes in which weak measurement offers a practical advantage for sensitive measurements.
