Application of variational quantum eigensolver for ground state energies calculation in hydrogen and helium atomic sequences

HIGHLIGHTS

  • What: This study provides a foundation for extending VQE to more complex quantum systems, such as molecular systems and periodic materials.
  • Who: SPEKTRA from the Department of Physics, University of Otago, Dunedin, New Zealand, Indonesia have published the paper: Application of Variational Quantum Eigensolver for Ground State Energies Calculation, in the Journal: (JOURNAL)

SUMMARY

    Quantum approaches, including quantum phase estimation (QPE), provide a more direct method for calculating ground_states but currently face scalability issues due to qubit and quantum gate demands, even for relatively small systems. That ansatz is optimized using . . .
