Quantum annealing eigensolver as a NISQ era tool for probing strong correlation effects in quantum chemistry
Aashna Anil Zade, Kenji Sugisaki, Matthias Werner +6
The quantum-classical hybrid variational quantum eigensolver (VQE) algorithm is arguably the most popular noisy intermediate-scale quantum (NISQ) era approach to quantum chemistry.…
