IBM Releases Qiskit Paulice to Embed Low-Overhead Spacetime Error-Detection Codes Directly into Near-Term Clifford Circuits

A quantum circuit demonstrating the structure of a singular spacetime Pauli check. The ancilla is represented by the purple qubit/top wire, and four target/payload qubits are represented in blue.

IBM Quantum has officially launched Qiskit Paulice (qiskit-paulice), an open-source Qiskit software add-on engineered to automatically identify, score, and inject hardware-efficient error-detection loops into arbitrary quantum circuits. Co-developed by IBM researchers Simon Martiel and Ali Javadi-Abhari, the package introduces spacetime Pauli checks to mitigate hardware noise profiles on current Noisy Intermediate-Scale Quantum (NISQ) chips.
