Qiskit addons
Qiskit addons are a collection of research capabilities for enabling algorithm discovery at the utility scale. These capabilities build on Qiskit's performant foundation of tools for creating and running quantum algorithms. They are provided as modular software components that can plug into a workflow to scale or design new quantum algorithms.
Addons for mapping
Approximate quantum compilation with tensor networks
Approximate quantum compilation with tensor networks (AQC-Tensor) enables the construction of high-fidelity circuits with reduced depth.

- Read the documentation.
Addons for optimizing
Operator backpropagation
Operator backpropagation (OBP) reduces circuit depth by trimming operations from the end at the cost of more operator measurements.
- Visit the GitHub repository.
- Read the documentation.
- Read the tutorial on using OBP to improve expectation values.
Circuit cutting
Circuit cutting reduces the depth of transpiled circuits by decomposing entangling gates between non-adjacent qubits.
