Locally Acting Grover Mixers for Constraint-Preserving QAOA
Minjin Choi, Dongkeun Lee, Junghee Ryu
The Grover mixer quantum alternating operator ansatz (GM-QAOA) employs the Grover mixer to confine the quantum evolution to the feasible subspace defined by the problem. Its mixing…

A variational quantum eigensolver tailored to multi-band tight-binding simulations of electronic structures
Dongkeun Lee, Hoon Ryu
We propose a cost-efficient measurement scheme of the variational quantum eigensolver (VQE) for atomistic simulations of electronic structures based on a tight-binding (TB) theory.…
