Press Release Overview
Mumbai, Maharashtra, India – On Thursday, 12 November 2026, LTM, an AI‑centric global technology services company and a Larsen & Toubro Group entity, announced that its proprietary AI‑powered Quantum Error Mitigation capability, AI‑QEM, is now available as a circuit function in the IBM Quantum Functions Catalog. This marks LTM as the first Global Systems Integrator worldwide to publish a function in the catalog.
IBM Quantum Functions Catalog Context
The IBM Quantum Functions Catalog is an ecosystem of partner‑built quantum software services designed to simplify quantum workflows and enable researchers and enterprises to run quantum experiments more efficiently for algorithm development and application prototyping.
AI‑QEM Capability Details
AI‑QEM is offered as a circuit function that can be invoked by users of eligible IBM Quantum access plans directly within their Qiskit workflows. The capability leverages advanced AI models to learn device‑specific error patterns and applies classical post‑processing to correct them, thereby improving result accuracy without requiring additional quantum processing unit (QPU) time, repeated circuit executions, or auxiliary qubits. This reduces both the cost and complexity of conducting useful quantum experiments.
Validation and Performance
The AI‑QEM function has been validated on IBM Quantum computers across a range of circuit sizes and complexities, including experiments involving more than 100 qubits. The validation demonstrates that the error mitigation works effectively on large‑scale quantum circuits.
Executive Comment
"LTM’s AI‑QEM now available in the IBM Quantum Functions Catalog reflects the growing role of our ecosystem partners in advancing and expanding the tools available for the wider quantum community. The AI‑QEM function will allow our users to mitigate errors faster and with fewer resources, in their efforts to develop algorithms and applications," said Scott Crowder, Vice President, IBM Quantum Adoption and Business Development.
LTM’s Broader Quantum Initiatives
LTM continues to develop practical quantum applications across industries, including quantum optimization solutions for a leading global insurer, hybrid quantum machine learning for critical infrastructure operations, and quantum‑safe security programs that help financial services and insurance organisations prepare for migration to post‑quantum cryptography.
