PolyU Researchers Develop World-First Quantum Microprocessor for Complex Molecular Spectroscopy Simulation

Researchers at The Hong Kong Polytechnic University (PolyU) have achieved a world-first breakthrough by developing a quantum microprocessor chip capable of simulating molecular spectroscopy for large-structured and complex molecules. This advancement overcomes significant computational limitations faced by classical computers in accurately modelling quantum effects like superposition and entanglement, which are crucial for understanding molecular properties. The developed system integrates hardware, software, and programmable quantum algorithms, paving the way for solving previously intractable quantum chemistry problems.
Novel Quantum Microprocessor Chip Developed

The core of this achievement lies in a newly developed 16-qubit quantum microprocessor chip. This chip is integrated into a single unit and forms the foundation of a complete quantum simulation system. The research, published in Nature Communications, details the fabrication and integration of this optical–electrical–thermal packaged chip alongside its electrical control module. This integrated approach is essential for capturing the complex quantum phenomena inherent in molecular interactions.
Enabling Simulation of Molecular Vibronic Spectra

This quantum microprocessor enables the simulation of molecular vibronic spectra, a task that has historically posed considerable challenges for classical computing due to its computational intensity. Traditional super-computers struggle with the accuracy and speed required for such simulations, often being limited to simpler molecular structures. The PolyU team's innovation allows for a more accurate and efficient study of these molecular properties, critical for molecular design and analysis.
Broad Applications in Quantum Chemistry and Beyond

The implications of this breakthrough extend to a wide range of complex quantum chemistry problems that are currently beyond the reach of classical computers. Potential applications include the simulation of large protein structures and the optimisation of molecular reactions, which could significantly accelerate discoveries in fields like pharmaceuticals. Furthermore, the quantum microprocessor is poised to be applied to molecular docking problems and advanced quantum machine learning techniques, such as graph classification.
Future Scaling and Intricate Applications

The research team, led by Professor LIU Ai-Qun and Dr ZHU Hui Hui, plans to scale up the capabilities of the microprocessor to address even more intricate applications. This ongoing development aims to unlock further potential in quantum information processing and real-world problem-solving, promising societal and industrial benefits. The ultimate goal is to create a fundamental building block for future quantum computing applications that can deliver quantum speed-ups in relevant quantum chemistry tasks.
