# Circuits

> Inspect a circuit's structure, cost and the jobs that ran it

export const Shot = ({name, alt}) => <Frame>
    <img className="block dark:hidden" src={`/images/dashboard/${name}.png`} alt={alt} />

Each circuit has its own details page. To open it, click the **Details** arrow on any row in **Experiment Circuits** or in a job's **Circuits** list.

<Shot name="circuit" alt="Circuit details page" />

| Section | What it shows |
| - | - |
| Header | The circuit name (click to rename), its **Source** (for example *User* or *Transpiled*), and the target device for transpiled circuits |
| Stats | **Qubit Count**, **2Q Depth**, and the total **QPU Cost** and **CPU Time** of all jobs that used this circuit |
| **Gate Counts** | How many gates of each type the circuit has, plus any **Tunable Parameters** |
| **Circuit Density Heat Map** | Gate activity per qubit (rows) and layer (columns). Hover over a cell for its value. Wide circuits scroll horizontally |
| **Circuit Diagram** | A text drawing of the circuit, like `haiqu.draw` |
| **Related Circuits** | The circuit this one was derived from, and circuits derived from it (for example, transpiled versions) |
| **Jobs Using This Circuit** | Every job that ran this circuit, with the same actions as [All Jobs](/dashboard/jobs) |

<Tip>
  To compare the original circuit with its transpiled or compressed versions, use the **Quantum volume** chart on the [experiment page](/dashboard/experiments#experiment-circuits).
