Qiskit addons

June 2026

• Introducing Qiskit Paulice: a new addon that integrates low-overhead quantum error detection into quantum circuits to boost the fidelity of measured distributions. It provides single-shot access to the quantum state and so can be used in both sampling-based and expectation value-based workflows. Check out the blog and documentation for how to get started today.

Previous updates

• We recently released two new addons that use classical resources to reduce the quantum resources needed for error mitigation:

  • Propagated noise absorption (PNA) is a technique for mitigating errors in expectation values by absorbing the inverses of the learned noise channels into observables using Pauli propagation.

  • The Shaded lightcones (SLC) addon uses classical simulations to more tightly bound the sensitivity to errors throughout the circuit. This allows for more efficient, targeted applications of Probabilistic Error Cancellation (PEC) with reduced variance.
