Digital Dynamical Decoupling

Digital Dynamical Decoupling (DDD) is an error mitigation technique in which sequences of gates are applied to slack windows, i.e. single-qubit idle windows, in a quantum circuit. Such sequences of gates can reduce the coupling between the qubits and the environment, mitigating the effects of noise. For more discussion of the theory of DDD, see the section What is the theory behind DDD?.

Workflow of the DDD technique in Mitiq, detailed in the What happens when I use DDD? section.

Below you can find sections of the documentation that address the following questions:

• How do I use DDD?
• When should I use DDD?
• What additional options are available when using DDD?
• What happens when I use DDD?
• What is the theory behind DDD?

Here is a tutorial on how to use DDD in Mitiq:
