Excited-State Workflows¶
Two categories are supported.
Post-VQE methods¶
Require a converged noiseless VQE reference.
LR-VQE
EOM-VQE
QSE
EOM-QSE
Example:
vqe -m H2 --lr-vqe --lr-k 4
Typical workflow:
VQE → response problem → excitation energies
Variational excited states¶
Optimised directly.
SSVQE
VQD
Example:
vqe -m H2 --vqd --k 3
