Lockheed Martin and IBM Demonstrate SQD-Based Quantum Simulation of Open-Shell Molecule

Lockheed Martin and IBM have applied sample-based quantum diagonalization (SQD) to simulate the electronic structure of methylene (CH₂), marking the first use of SQD for an open-shell molecule. The collaboration highlights SQD as a strong candidate for near-term quantum advantage, capable of modeling strongly correlated systems that challenge classical computational chemistry. In this study, the […]
