QunaSys Launches Partner Program and Technical Portal to Advance Quantum Algorithm
Summarize this article with:
QunaSys Inc. has launched both a QSCI Technical Portal and an official partner program aimed at accelerating the commercial deployment of its Quantum-Selected Configuration Interaction algorithm. Originally published in February 2023, QSCI addresses limitations in current quantum computing by combining quantum-native sampling with large-scale classical computation, enabling more realistic problem solving on existing devices and demonstrated through initiatives with RIKEN and IBM. This expansion builds upon growing international research and development, with recent contributions from Keio University and IBM, and seeks to establish a global QSCI ecosystem. “Quantum computing will not reach industrial impact through hardware advances alone,” said Tennin Yan, CEO of QunaSys. “Algorithms that fully leverage hardware capabilities are equally essential.” QSCI Algorithm Bridges NISQ Limitations with Quantum-HPC Hybridization QunaSys is addressing a fundamental hurdle in near-term quantum computing—the limited usability of available qubits—with its Quantum-Selected Configuration Interaction (QSCI) algorithm, initially published in February 2023. While algorithms like Variational Quantum Eigensolver (VQE) often struggle with noise and scaling, QSCI enables the execution of significantly larger and more realistic problem instances on existing quantum devices, a feat demonstrated in collaborative initiatives with RIKEN and IBM utilizing the Fugaku supercomputer and IBM quantum processors. This approach extends beyond quantum chemistry, now being applied to optimization and other computationally intensive fields. Recent advancements in both quantum hardware and algorithmic design have demonstrably increased the scale of problems validated on physical quantum systems, with QSCI playing a key role in these improvements. Compared to traditional methods, QSCI has facilitated larger-scale demonstrations on real devices, bringing practical industrial applications of quantum computing closer to reality. Research from Keio University, QunaSys, and IBM on time-evolution-based state preparation further underscores the growing international momentum surrounding the algorithm, prompting the launch of the QSCI Technical Portal, dubbed “Awesome QSCI,” to provide a comprehensive overview of the technology’s development and ecosystem. The company is actively seeking collaboration with both hardware vendors and enterprise partners interested in early-stage deployment of QSCI-based solutions. QunaSys Launches QSCI Portal and Partner Program for Commercialization QunaSys, a Tokyo-based firm specializing in quantum computing software, is actively fostering the expansion of its Quantum-Selected Configuration Interaction (QSCI) algorithm through the establishment of a dedicated technical portal and a partner program for hardware vendors. Originally detailed in February 2023, QSCI has progressed from initial research to a deployable methodology operating within quantum–HPC hybrid environments, addressing limitations inherent in current noisy intermediate-scale quantum (NISQ) devices. The algorithm uniquely combines quantum-native sampling with large-scale classical matrix computation, enabling the execution of more complex problems on existing quantum hardware and overcoming the constraints of limited, usable qubit counts. Demonstrations leveraging QSCI have already involved collaborations with RIKEN and IBM, integrating the Fugaku supercomputer with IBM quantum processors. The newly launched QSCI Technical Portal, dubbed “Awesome QSCI,” serves as a central repository for companies assessing the adoption of this technology, providing insight into its development, maturity, and the broader ecosystem. QunaSys emphasizes a distinction between QSCI and Sample-based Quantum Diagonalization (SQD) within the portal’s resources, aiming to clarify the algorithmic approach. Beyond its initial application in quantum chemistry, QSCI is now being extended to optimization problems and other computationally intensive fields, reflecting a broadening scope of potential applications. Recent advancements in state preparation techniques, noise resilience, and subspace construction are all contributing to the algorithm’s increasing capabilities. To further accelerate commercial deployment, QunaSys has initiated an official partner program targeting quantum hardware vendors, offering joint technical optimization, enterprise implementation support, and a structured intellectual property framework. QSCI represents a key milestone in that direction.” The company anticipates that QSCI integration will provide hardware vendors with a demonstrable use case, supporting market differentiation and accelerating the path toward practical quantum advantage. Quantum computing will not reach industrial impact through hardware advances alone.
