Talk / Overview

In quantum computing, state preparation is the problem of synthesizing circuits that initialize quantum systems to specific states. It has been shown that there are states that require circuits of exponential size to be prepared, and consequently, despite extensive research on this problem, the existing general methods produce circuits of exponential size. In this talk, I show how state preparation can be made scalable by using techniques that are unique to quantum computing: measurements, and the resulting state collapses. With this approach, we are able to produce wide classes of states in polynomial time, resulting in an exponential improvement over existing methods.
