Project #1
Promotion of Quantum Computing Technology and Exploration of Use Cases
We aim to form communities and develop human resources related to quantum computing technology. By increasing the number of individuals capable of handling quantum computers in both academia and industry, we seek to promote the field itself. Specifically, we provide opportunities for students to experience everything from basic learning to research through lectures and group work in study sessions. We also prepare environments where students can engage in research and development that address corporate needs in academia-industry co-creation settings. The increase in quantum computing professionals is essential for exploring use cases.

The university has established itself as a world-class center for quantum computing research and education
Osaka University, the leading institution of the Quantum Software Research Hub, has been conducting research and education in quantum information technology for over 25 years, offering comprehensive undergraduate and graduate courses. This history places it among the world's top institutions in the field.

Project #2
Application Research and Development in Machine Learning, Mathematical Data Science, and Finance
We are building quantum computing libraries for machine learning (AI), Monte Carlo simulations, mathematical data science, and finance, enabling faster and more accessible computations compared to traditional computers. Additionally, we are developing novel quantum algorithms and advancing Proof of Concept (PoC) using both simulators and actual devices.

Our team was one of the earliest to introduce quantum machine learning algorithms tailored for NISQ systems
We were among the first to propose the quantum machine learning algorithm "QCL" for NISQ machines, which has been cited in approximately 200 publications over two years. It has also been adopted as a standard method in TensorFlow Quantum (Google) and PennyLane (Xanadu).

Project #3
Application Research and Development in Materials, Chemistry, and Physical Properties
Through molecular simulations using quantum computers, we aim to analyze previously unknown chemical reactions involved in processes like nitrogen fixation and photosynthesis. We are constructing the necessary libraries for these simulations and researching related algorithms. Our research themes include problem decomposition methods to solve large problems with limited qubits, introduction of multiscale and multiphysics approaches for handling complex systems, and development of algorithms and support tools anticipating fault-tolerant quantum computers.

Project #4
Implementation of NISQ-Based Technologies, Simulation Techniques, and Fault-Tolerant Quantum Computing Architectures
We are building software infrastructure tools that maximize the performance of NISQ machines and fault-tolerant quantum computers, making them more accessible. Our research themes include developing quantum circuit synthesis and optimization methods, noise compensation techniques, constructing and demonstrating quantum-classical hybrid algorithms that coordinate supercomputers and quantum computers, and establishing software tools (decoding, quantum circuit synthesis) for fault-tolerant quantum computers.

Project #5
Development of a Cloud Environment for Integrated Control of Quantum and Classical Computers
We are creating an environment where quantum computers can be accessed via cloud services. This cloud environment allows transparent control of Osaka University's quantum computers, external quantum computers, supercomputers, and simulators on local PCs. By enabling access from various computers, we facilitate efficient research and development of quantum software.

Our team fosters deep interdisciplinary understanding between professionals in classical and quantum computing.
Our team, SDLab, consisting of professionals in classical information systems, quantum hardware, and quantum software development, has been active for over 10 years, conducting more than 30 workshops, and establishing a collaborative framework.

Project #6
Development of General-Purpose Quantum Middleware for Platform Realization Defined by Quantum Software
We are developing quantum middleware that connects quantum hardware and quantum software, expanding usability. Since devices controlling qubits in quantum hardware cannot directly connect with quantum software, we are creating quantum middleware that controls quantum states by applying microwaves to qubits, bridging the gap between quantum software and hardware.

Takefumi Miyoshi
(Specially Appointed Professor, Center for Quantum Information and Quantum Biology, Osaka University)
General-purpose quantum middleware
We aim to develop general-purpose quantum middleware capable of controlling a wide range of quantum computing platforms, including superconducting, ion-trap, semiconductor, optical, and molecular systems. While some middleware exists for specific or combined systems, a versatile solution has yet to be developed.

Project #7
Development of a Platform-Type Quantum Computer Testbed
In collaboration with other research and development projects, we are constructing a testbed environment that can connect with various types of quantum computers, including superconducting and ion-trap systems, providing development environments for quantum software developers.
