  • The 2025 R&D Forum is an invite-only event hosted by NTT Group companies in Tokyo from Nov. 19-21 and Nov. 25-26, 2025. For more information, visit the event webpage.

NTT, Inc. (NTT) is hosting their annual R&D Forum Nov. 19-21 and Nov. 25-26 in Tokyo to demonstrate the company’s technological leadership in the fields of optical and quantum computing, artificial intelligence, digital security, mobility, infrastructure and more. The theme of this year’s forum is IOWN: Quantum Leap following the United Nations’ designation of 2025 as the “International Year of Quantum Science and Technology.” The Japanese government has also designated 2025 as the first year of quantum industrialization.

IOWN Takes a Quantum Leap Forward

NTT is exhibiting recent breakthroughs of its Innovative Optical and Wireless Network (IOWN) Initiative, which aims to realize an advanced communications infrastructure with optical photonics technologies achieving ultra-high capacity, ultra-low latency and ultra-low power consumption.

  • NTT and OptQC Sign Agreement to Realize Scalable, Reliable and Practical Optical Quantum Computers: NTT and OptQC have signed an agreement to collaborate on the realization of scalable and reliable optical quantum computers. The agreement will apply optical communications technologies developed by NTT under the IOWN Initiative with OptQC's world-first optical quantum computer that operates at room temperature and pressure. The companies aim to create a 1-million qubit optical quantum computer by 2030. [Read the Full Release]

NTT Demonstrates AI Leadership

Several exhibitions at the NTT R&D Forum demonstrate NTT’s role as a leader in global AI innovation, including technologies transforming enterprise and organizational workflows today as well as research developments advancing the future of AI capabilities.

  • NTT's Next-Generation LLM "tsuzumi 2" Now Available: In October, NTT announced the next evolution of its proprietary, built-from-scratch LLM, tsuzumi, with tsuzumi 2. The new LLM is a lightweight model aimed at overcoming the electricity consumption, rising operating costs and security risks of competitor LLMs. In business-case deployments, tsuzumi 2 is proven to deliver performance on par with or exceeding that of larger models while offering a superior cost-performance ratio.

The Future of Digital Privacy and Security

Concurrent to its development of advanced computation capabilities, NTT researchers are developing and deploying leading-edge cybersecurity systems to contend with the growing threat of quantum and AI-based cyberattacks.

  • NTT Research Announces Quantum-Secure Zero Trust Data Security Suite: NTT Research, the Silicon Valley-based fundamental research arm of NTT, announced a new set of cybersecurity solutions powered by attribute-based encryption (ABE) to combat the rising threat of quantum computing and AI. ABE, which enables fine-grain access control and enforcement policies, was first proposed by NTT Research Cryptography & Information Security Lab Director Dr. Brent Waters and his co-author, Dr. Amit Sahai, in a 2005 paper, “Fuzzy Identity-based Encryption.” [Read the Full Release]

Autonomous Mobility

Building upon years of research and development of advanced networking technologies, NTT has launched a new company to transform the future of autonomous driving.

  • Establishment of NTT Mobility, Inc.: NTT announced that it has formed NTT Mobility, a new venture capitalizing on the company’s networking expertise to drive level 4 autonomous vehicle adoption across Japan. NTT aims to offer autonomous driving services throughout Japan by fiscal year 2027, with three primary business activities: autonomous driving vehicle provision and management services; autonomous driving implementation and operation support services; remote monitoring system provision services. [Read the Full Release]
  • Automatic Evaluation of Remote Monitoring Video Quality for Level 4 Autonomous Driving: NTT announced the parametric object-recognition-radio-estimation model, a new technology automatically estimates whether remote monitoring video and vehicle-related information transmitted from autonomous vehicles to the control room are of sufficient quality to reliably detect objects suddenly appearing in front of the vehicle. This technology will enhance autonomous driving safety by generating alerts if the quality of remote monitoring video deteriorates and safe supervision is compromised. [Read the Full Release]
