What is a Quantum Computer?

Quantum computers are gaining attention as an emerging technology poised to shape the future of society through their extraordinary computational capabilities, making possible what was once only imaginable. While realizing this future requires the development of various technologies, recent technical advances are bringing the dream of a “Quantum Computer” closer to reality. This indicates that the quantum industry is approaching a major turning point. In this context, concrete efforts to apply quantum technology are now progressing in earnest within the industrial sector.

QunaSysとは /  About Us :

QunaSysは「量子コンピュータが産業に貢献する未来へ。」をミッションとして、量子コンピュータの性能を最大限に引き出すためのアルゴリズムやソフトウェアを開発しており、量子コンピュータの社会実装に貢献します。

NISQ誤り訂正機能を持たない小中規模の量子コンピュータからEarly-FTQC初期的な誤り耐性量子コンピュータそして本格的なFTQC誤り耐性量子コンピュータへと移行しつつあります。そうした中、QunaSysは、産業界の現実課題に即して、アルゴリズムアーキテクチャハードウェア横断的に、アプリケーションの性能評価を行い、開発を加速するソフトウェア開発基盤を開発・提供しています。

The practical use of quantum computers depends not only on advances in hardware but also on progress in algorithms and software to make the technology truly usable. At QunaSys, our mission is to “Build the future where quantum computers contribute to industry.” We develop algorithms and software to maximize the performance of quantum computers, thereby contributing to their integration into society.

The journey toward practical quantum computing is evolving from NISQ (Noisy Intermediate-Scale Quantum Computers, which lack error correction) to Early-FTQC (early Fault-Tolerant Quantum Computers), and ultimately to full-scale FTQC (Fault-Tolerant Quantum Computers). In this evolving landscape, QunaSys addresses real-world industrial challenges by evaluating application performance across algorithms, architectures, and hardware. We also develop and provide a software development platform that accelerates this progress.

The QS (Quantum Solution) team develops software, ranging from algorithms to Architecture, for current NISQ devices, next-generation Early-FTQC, and future FTQC systems, such as the QURI SDK.

Why We Are Hiring :

FTQCの実現に向けて、量子ハードウェアと、それに適したアーキテクチャに対応するコンパイラ基盤の重要性が高まっています。

QunaSysでは、FTQCを実機上で実現するために不可欠な量子コンパイラの開発を強化するとともに、ユーザーが定義した量子アルゴリズムを各種アーキテクチャにマッピングし、性能評価を行うQURI SDKへの統合を進めています。これにより、複雑化する量子アプリケーション開発において、より高いユーザー価値の提供を目指します。

IR中間表現、ISA命令セットアーキテクチャ、変換・最適化パスの開発に携わるエンジニアを求めています。

As the quantum industry advances toward the realization of FTQC, the importance of compiler infrastructure that supports quantum hardware with appropriate architecture is growing rapidly.

At QunaSys, we are strengthening the development of quantum compilers—an essential component for implementing FTQC on real hardware—and integrating them into the QURI SDK. This SDK includes features to evaluate performance by mapping user-defined quantum algorithms to various architectures. Through these efforts, we aim to deliver greater value to users and become the top choice in the increasingly complex field of quantum application development.

For this role, we are seeking engineers to develop intermediate representation (IR), Instruction Set Architecture (ISA), and transformation / optimization passes that will drive our progress forward.
