The rapid progress in quantum computing has opened up new possibilities for tackling complex scientific problems. Variational quantum eigensolver (VQE) holds the potential to solve…
Adaptive variational algorithms for quantum Gibbs state preparation
Ada Warren, Linghua Zhu, Nicholas J. Mayhall +2
The preparation of Gibbs thermal states is an important task in quantum computation with applications in quantum simulation, quantum optimization, and quantum machine learning. How…
Observation of Flat Frequency Bands at Open Edges and Antiphase Boundary Seams in Topological Mechanical Metamaterials
Kai Qian, Linghua Zhu, Keun Hyuk Ahn +1
Motivated by the recent theoretical studies on a two-dimensional (2D) chiral Hamiltonian based on the Su-Schrieffer-Heeger chains, we experimentally and computationally demonstrate…
Efficient Symmetry-Preserving State Preparation Circuits for the Variational Quantum Eigensolver Algorithm
Bryan T. Gard, Linghua Zhu, George S. Barron +3
The variational quantum eigensolver is one of the most promising approaches for performing chemistry simulations using noisy intermediate-scale quantum (NISQ) processors. The effic…
Flat Energy Bands within Antiphase and Twin Boundaries and at Open Edges in Topological Materials
Linghua Zhu, Emil Prodan, Keun Hyuk Ahn
A model for two-dimensional electronic, photonic, and mechanical metamaterial systems is presented, which has flat one-dimensional zero-mode energy bands and stable localized state…
