What is the significance of the FeMoCo molecule in this research and its industrial applications?

FeMoCo is the active center of nitrogen fixation enzymes, and its accurate electron structure calculation is crucial for designing new catalysts in the agrochemical and fertilizer industries.

What was the estimated qubit requirement for FeMoCo electron structure calculation, and why is it considered a 'killer application'?

In 2017, it was estimated that 108 qubits would be required for FeMoCo electron structure calculation, making it a long-term goal and a 'killer application' for quantum computers.

What were the key findings of H.I.Council's research, beyond the 108-qubit calculation?

The research demonstrated that FeMoCo calculations can be achieved for a 48-qubit system using a classical pipeline and quantitatively clarified the limitations of current quantum computers, the 'coherence wall'.

Where can the academic papers detailing H.I.Council's research be accessed?

The papers are available on the preprint server ChemRxiv (DOI: 10.26434/chemrxiv.15001770/v2) and the open-access repository Zenodo (DOI: 10.5281/zenodo.19463795).

AI Summary (NQ-processed)

H.I.Council, a deeptech company based in Shibuya, Tokyo, led by Futoshi Hamanoue, has successfully executed the world's first 108-qubit electron structure calculation of the FeMoCo molecule on IBM's ibm_pittsburgh quantum computer (Heron r2, 156 qubits). The research, published on ChemRxiv and Zenodo, achieved a statistical error of ±0.67 mHa and identified the "coherence wall" as a quantitative limit for current quantum computers. Notably, the study also demonstrated that chemical precision for a 48-qubit FeMoCo system can be achieved using classical quantum chemistry methods (DMRG-AFQMC pipeline), challenging the long-held belief that such calculations required quantum computers. The company has also filed a patent (JP Patent Application 2025-182361) and proposed three directions for future quantum hardware improvement.
