Understanding the differences between simulators
In this section, you will learn about the various simulator backends that are included in Qiskit Aer, including the differences between them and their distinct features. Note that you will need to install qiskit-aer separately as it is not part of the base Qiskit install.
These features include generating noise models and configuring the simulator backends that allow you to take advantage of modifying their behavior and characteristics to suit your needs.
We will learn about the following simulators and their key features:
- The Aer simulator, which executes a quantum circuit with multiple shots to simulate a noisy backend quantum system
- The Statevector simulator, which provides the state vector of the quantum circuit
- The Unitary simulator, which provides the unitary matrix of the quantum circuit being executed
Let’s move on and look at the quantum systems, herein referred to as simply backends...
