# Qubits Summary

## New Types of Computation

This guide is intended for those who already have a strong foundational understanding of computer systems and how they work. As such we'll start our discussion of quantum bits with just a very brief review of classical bits and how they work.

Quantum bits take advantage of the property of superposition to contain multiple pieces of information at the same time. This is a little weird when you first get into it, but overall is very interesting.

## Material

In this section we'll cover classical bits, classical registers, quantum bits and the Bloch sphere:

#### Review Material

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://lewisla.gitbook.io/learning-quantum/qubits/qubits-summary.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
