LTM Lists Its AI-QEM Tool in IBM's Quantum Functions Catalog

LTM, the IT services company formerly called LTIMindtree, said on November 12, 2026 that AI-QEM, its AI-powered quantum error mitigation tool, is now available in the IBM Quantum Functions Catalog. LTM said it is the first global systems integrator (GSI) to publish a function in the catalog.

LTM said AI-QEM is offered as a circuit function. Users of eligible IBM Quantum access plans can apply it directly inside their Qiskit workflows, according to the company. LTM, a Larsen & Toubro Group company, announced the listing from Mumbai.

How LTM says AI-QEM cleans up quantum errors

Quantum computers are prone to noise and errors that can affect their results. LTM said common ways of reducing these errors often need extra circuit runs, more quantum processing time or additional qubits. AI-QEM instead uses AI models to learn the error patterns of a specific device and correct them through classical post-processing, the company said.

According to LTM, this improves the accuracy of results without extra quantum processing unit (QPU) time, repeated circuit runs or extra qubits. LTM said the tool has been tested on IBM Quantum computers across circuits of different sizes, including experiments with more than 100 qubits. The IBM Quantum Functions Catalog is a collection of quantum software services built by IBM's partners, which researchers and companies can use in their quantum work.

IBM's Scott Crowder on what AI-QEM offers users

"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."

LTM's other quantum computing work

LTM said its quantum work also includes quantum optimisation solutions for a global insurer and hybrid quantum machine learning for critical infrastructure operations. The company said it also runs quantum-safe security programmes that help financial services and insurance organisations prepare for the move to post-quantum cryptography.

Where LTM stands in IBM's quantum catalog

LTM now has AI-QEM listed as a circuit function in the IBM Quantum Functions Catalog, and the company said it is the first global systems integrator to publish there. The tool is open to users of eligible IBM Quantum access plans through their Qiskit workflows, and LTM said it has been tested on circuits with more than 100 qubits.
