Accelerating Multiple Sequence Alignment with Quantum Computing

Hello, I'm Yusuke Kimura from the Quantum Applications CPJ at the Quantum Laboratory.

I have been focusing on genome analysis as one of the application areas for quantum computers. Recently, we implemented part of Multiple Sequence Alignment (MSA)—one of the important techniques in genome analysis—as a quantum circuit, and simulated it efficiently using our decision diagram (DD)-based quantum circuit simulator. The work has been published on arXiv. In this article, I'll introduce the contents of the paper in an easy manner.

Breakthrough quantum technology slashes computational requirements for molecular modelling

In recent years, quantum computers have been garnering attention as a next-generation technology. From healthcare and materials development to the energy sector, their potential applications are virtually limitless. However, significant hurdles still stand in the way of practical implementation. In particular, the issue of qubit errors is severe, and achieving high-accuracy computations requires redundancy to correct these errors. Consequently, realistic computations would require around millions of qubits—a technology that currently remains far in the future.

To address this challenge, we have devised a groundbreaking approach. At Fujitsu Quantum*1, we have developed two core technologies: the “STAR Architecture ver. 3”, jointly developed by Fujitsu and The University of Osaka*2 based on the Fujitsu Small Research Lab*3 and “molecular model optimization technology.” Through these, we have succeeded in breaking through the limitations of conventional quantum computers.*4

These technologies will dramatically accelerate the industrial application of quantum computers in the “Early-FTQC era,” characterized by systems with tens of thousands of qubits.They hold the potential to make significant contributions to solving pressing societal challenges, such as shortening the development time for pharmaceuticals and new materials and improving the energy efficiency of chemical compound manufacturing. In this article, we will provide an easy-to-understand explanation of the details and future prospects of these innovative technologies. While it is a bit lengthy, if you read through to the end, the future of quantum computing will surely become much clearer!

The Case for Harness Engineering: Achieving SLM SOTA on SWE-bench Verified with a 27B Model (TTS@8 = 74.8%)

Using Qwen3.5-27B without any fine-tuning, we achieved 74.8% (374/500) on SWE-bench Verified — a benchmark that measures how well a model can fix real OSS issues from GitHub — by generating 8 candidate patches and selecting the best one. This is the highest score*1 among local LLMs with fewer than 229B parameters.

Introducing Fujitsu KG Enhanced RAG (6 sessions) #6 Knowledge Publication - publishing "Usable Knowledge" rather than raw data

Hello. We are Kikuzuki, Narita, Kikuchi, Miyahara from the Artificial Intelligence Laboratory.

To promote the use of generative AI at enterprises, Fujitsu has developed a generative AI framework for enterprises that can flexibly respond to diverse and changing corporate needs and easily comply with the vast amount of data held by a company and laws and regulations. The framework was successfully launched in July 2024 as part of Fujitsu Kozuchi (R&D)'s AI service lineup.

Some of the challenges that enterprise customers face when leveraging specialized generative AI models include:

  • Difficulty handling large amounts of data required by the enterprise
  • Generated AI cannot meet cost, response speed, and various other requirements
  • Requirement to comply with corporate rules and regulations

To address these challenges, the generative AI framework for enterprises consists of the following technologies:

  • Fujitsu Knowledge Graph enhanced RAG( *1 )
  • Amalgamation Technology
  • Generative AI Audit Technology

In this series, we introduce the "Fujitsu Knowledge Graph enhanced RAG" every week. We hope this helps you solve your problems. At the end of the article, we'll also tell you how to try out the technology.

*1: RAG technology: Retrieval Augmented Generation. A technology that extends the capabilities of generative AI by combining it with external data sources.

Toward the Social Implementation of Ocean Digital Twin ~ Demonstration of Seaweed Bed Quantification Technology for Multi‑Species Seaweed Beds ~

Hello, we are Tatsuya Suzuki from the Converging Technologies Research Laboratory and Kazuya Ijuin from the Human Digital Twin Division.

We are engaged in the research and development of the Ocean Digital Twin, which digitally reproduces marine environments to support environmental conservation and industrial applications. As part of this initiative, we are developing seaweed bed quantification technologies that quantitatively evaluate the amount of CO₂ absorbed by seaweed and other marine vegetation and enable their utilization as carbon credits. To date, we have demonstrated the effectiveness of our technology by obtaining certification under J‑Blue Credit, Japan’s domestic blue carbon credit scheme, for seaweed beds consisting of a single seaweed species.
(Reference: Uwaijima Initiative! Collaborative Blue Carbon Project for Eelgrass Restoration by Fisheries Cooperatives, Communities, and Local Government (in Japanese))

Currently, we are advancing these research outcomes toward real‑world business applications and social implementation through Proof of Concept (PoC) activities. In this article, we introduce one such initiative: a demonstration conducted in Yamaguchi Prefecture targeting seaweed beds where multiple seaweed species coexist.

When AI 'Sees' What Isn't There: Introducing a Benchmark for Diagnosing Hallucinations in Multimodal Large Language Models (MLLMs)

Hello. We are Ziqiang Shi, Liu Liu, Zihao Guo from the Artificial Intelligence Laboratory at Fujitsu Research & Development Center (Beijing). Today, we are pleased to present our research findings on a critical yet often overlooked challenge facing MLLMs: the phenomenon where models overly rely on language-derived knowledge, confidently generating responses that contradict visual information. We have named this phenomenon ECHO (EvidenCe-prior Hallucination Observation). To address this issue, we propose the first dedicated benchmark, the Fujitsu Hallucination Benchmark, along with mitigation strategies that leverage this benchmark.
