Parameterization and optimizability of pulse-level VQEs
Kyle M Sherbert, Hisham Amer, Sophia E Economou +2
In conventional variational quantum eigensolvers (VQEs), trial states are prepared by applying series of parameterized gates to a reference state, with the gate parameters being va…
Hilbert Space Fragmentation and Subspace Scar Time-Crystallinity in Driven Homogeneous Central-Spin Models
Abhishek Kumar, Rafail Frantzeskakis, Edwin Barnes
We study the stroboscopic non-equilibrium quantum dynamics of periodically kicked Hamiltonians involving homogeneous central-spin interactions. The system exhibits a strong fragmen…
Reducing measurement costs by recycling the Hessian in adaptive variational quantum algorithms
Mafalda Ramôa, Luis Paulo Santos, Nicholas J. Mayhall +2
Adaptive protocols enable the construction of more efficient state preparation circuits in variational quantum algorithms (VQAs) by utilizing data obtained from the quantum process…
