LTM Becomes First Global Systems Integrator to Launch Function in IBM Quantum Functions Catalog with AI-QEM

AI-summarised brief · reviewed before publication

Larsen & Toubro’s technology arm, LTM, has become the first global systems integrator to publish a circuit function on IBM’s Quantum Functions Catalog. Its AI‑QEM software, accessible via the lt‑m/ai‑qeminterface, integrates with Qiskit Estimator workflows to reduce hardware noise using deep‑learning inference. The approach bypasses extra quantum sampling by rescaling noisy expectation values with trained neural networks, achieving a mean absolute error of 0.343 across 80‑ to 150‑qubit tests, outperforming traditional mitigation baselines. IBM Quantum provides tutorials and API documentation for the new function.

💡 Why It Matters

  • · By eliminating the need for costly circuit ensembles, LTM’s AI‑QEM could lower quantum runtime costs and accelerate practical applications on noisy hardware.
  • · The integration demonstrates a scalable, software‑centric path to higher‑fidelity quantum computations.
