Quantum AI isn’t enterprise-ready yet, says Gartner report

Gartner has predicted that Quantum AI will not run enterprise AI workloads at scale before 2028, stating that classical accelerated AI will continue to dominate production environments. The research firm also said fault-tolerant quantum computing is expected to remain in the research and development phase for AI through 2030.

According to Gartner, growing interest in quantum technologies should not be confused with production readiness, as enterprise AI continues to rely on conventional computing infrastructure.

Gartner separates Quantum AI from quantum computing

Gartner defines Quantum AI as artificial intelligence or machine learning techniques that require execution on quantum hardware to achieve a performance, cost, or capability advantage over classical computing.

The company said many vendor claims around Quantum AI actually refer to hybrid quantum-classical approaches or quantum-inspired algorithms rather than quantum-native AI running on enterprise-scale quantum hardware. Gartner added that no peer-reviewed results have demonstrated quantum advantage for production AI workloads.

The report distinguishes Quantum AI from three existing approaches: Classical Artificial Intelligence running on CPUs, GPUs, and TPUs, quantum-inspired AI algorithms operating on conventional hardware, and hybrid quantum-classical workflows currently used for research and pilot projects.

Gartner recommends keeping AI and quantum budgets separate

According to the report, organisations should maintain separate investment strategies for quantum research and production AI because the technologies have different timelines, economics, and governance requirements.

According to the company, Generative AI is already delivering measurable business value within 12 to 18 months through automation, improved accuracy, and operational efficiency. In contrast, Quantum AI has not demonstrated measurable value for production workloads and is unlikely to do so in the near future.

Recommendations for Quantum AI enterprise adoption

To prepare for future Quantum AI enterprise adoption, Gartner recommends that organisations deploy quantum-inspired algorithms within existing AI infrastructure instead of relying on quantum hardware, define clear success metrics and exit criteria before launching quantum pilots, and monitor progress in logical qubits, error correction, and quantum control instead of focusing on physical qubit counts.

According to Gartner, these measures can help organisations evaluate quantum technologies while continuing to invest in AI platforms that are already delivering business outcomes.
