NTT DoCoMo Business is adding quantum software to its enterprise offering through a partnership with Classiq, aiming to help Japanese customers turn potential applications into testable algorithms.

Under a memorandum of understanding, the company formerly known as NTT Communications will market and sell Classiq’s development platform and help customers develop and evaluate quantum computing use cases. Classiq will supply the software and technical expertise.

The partnership gives Classiq a route to customers through an ICT provider experienced in deploying networks, cloud services, and AI infrastructure. The companies plan joint customer engagements to assess business problems and support quantum algorithm development and execution.

Cutting the circuit-design workload

Access to a quantum computer is only part of the challenge. Developers also have to translate an algorithm into quantum circuits and adapt those circuits to the hardware running them.

Classiq’s platform uses its Qmod modeling language and an automated synthesis engine to generate circuits from higher-level descriptions, optimizing them against specified constraints and hardware requirements. NTT says this can make quantum development more accessible to engineers and data scientists with expertise in AI, machine learning, or linear algebra.

The platform combines that automation with agentic AI interfaces and supports simulators and superconducting, neutral-atom, trapped-ion, and photonic hardware. According to the companies, developers can target different supported quantum architectures without rewriting their algorithms, choosing execution targets according to application needs and available machine time.

“Japan has a strong base of enterprises already exploring how quantum computing can contribute to their long-term technology strategies,” Akira Tanaka, Classiq’s VP and head of its Asia-Pacific (APAC) region, explained in the announcement.

Potential applications include materials development, drug discovery, financial calculations, logistics, and network optimization. The announcement did not identify customer deployments, report performance benchmarks, financial terms, or delivery milestones.

A broader quantum infrastructure push

NTT DoCoMo Business is also involved in quantum-secure communications infrastructure. In June, it announced the start of construction with Toshiba and NEC of a roughly 373-mile quantum key distribution (QKD) network connecting Tokyo, Nagoya, and Osaka. The project targets secure communications for organizations handling sensitive information, including health care, finance, and electricity providers.

NTT will coordinate the demonstration and provide the network, data centers, and applications, while Toshiba and NEC will supply QKD equipment and help build and test the network. The June announcement described construction followed by trials of performance, stability, security, and operational manageability rather than a completed commercial service.
