# Circuit Execution

> In this example, you'll learn how to execute quantum circuits using the Haiqu SDK on a variety of backends — from ideal simulators to real quantum hardware (e.g. via IBM Quantum). We will cover different scenarios and walk you through the steps required to execute the circuits on a quantum device or simulator.
