Efficient symmetry-preserving state preparation circuits for the variational quantum eigensolver algorithm
Efficient symmetry-preserving state preparation circuits for the variational quantum eigensolver algorithm
The variational quantum eigensolver is one of the most promising approaches for performing chemistry simulations using noisy intermediate-scale quantum (NISQ) processors. The efficiency of this algorithm depends crucially on the ability to prepare multi-qubit trial states on the quantum processor that either include, or at least closely approximate, the actual …
