Abstract : Chemical dissociation processes are important in quantum dynamics. which gives a quantum mechanical description of molecular dynamics.

Because matchgates can be mapped to non-interacting fermions, these circuits can be efficiently simulated on a classical computer. One can perform universal quantum computation by adding any nonmatchgate parity-preserving gate, implying that interacting fermions are natural Optimized quantum algorithms present solution to Fermi-Hubbard model on near-term hardware. Researchers from the University of Bristol and quantum start-up, Phasecraft, have advanced quantum computing research, bringing practical hybrid quantum-classical computing one step closer. Abstract. The Fermi-Hubbard model is of fundamental importance in condensed-matter physics, yet is extremely challenging to solve numerically. Finding the ground state of the Hubbard model using variational methods has been predicted to be one of the first applications of near-term quantum computers.
