>Mapping the distribution of water molecules within protein cavities is essential, but computationally demanding – particularly when investigating buried or occluded pockets. Quantum computing specialists Pasqal are collaborating Qubit Pharmaceuticals to develop a hybrid quantum-classical approach for analyzing protein hydration. This approach combines classical algorithms to generate water density data and quantum algorithms to precisely place water molecules inside protein pockets, even in challenging regions.

>By utilizing quantum principles such as superposition and entanglement, our quantum methods evaluate numerous configurations far more efficiently than classical systems. We successfully implemented this algorithm on Orion, our neutral-atom quantum computer, marking the first time a quantum algorithm has been used for a molecular biology task of this importance. This is a significant step forward in revolutionizing computational drug discovery.
