This document provides an overview of quantum computing. It begins with a short history and addresses the need for quantum computing to be faster than classical computing. It explains that while classical bits can only be 1 or 0, quantum bits or qubits can be both 1 and 0 simultaneously using superposition. The document notes that nobody fully understands quantum computing because it describes nature in a way that seems absurd. It provides an example of Google working with quantum computing and discusses some of the challenges like keeping qubits from losing their state due to low temperatures and errors. In the end, it suggests that quantum computing has great potential power.Read less
