Minimum measurements quantum protocol for band structure calculation
Michal KrejÄÃ, Lucie KrejÄÃ, Ijaz Ahamed Mohammad +2
Protocols for quantum measurement are an essential part of quantum computing. Measurements are no longer confined to the final step of computation but are increasingly embedded wit…
Efficient implementation of single particle Hamiltonians in exponentially reduced qubit space
Martin Plesch, Martin Friák, Ijaz Ahamed Mohammad
Current and near-term quantum hardware is constrained by limited qubit counts, circuit depth, and the high cost of repeated measurements. We address these challenges for solid stat…
Classical Regularization in Variational Quantum Eigensolvers
Yury Chernyak, Ijaz Ahamed Mohammad, Martin Plesch
While quantum computers are a very promising tool for the far future, in their current state of the art they remain limited both in size and quality. This has given rise to hybrid…
HOPSO: A Robust Classical Optimizer for VQE
Ijaz Ahamed Mohammad, Yury Chernyak, Martin Plesch
Variational Quantum Eigensolver (VQE) algorithm is one of few approaches where the hope for near-term quantum advantage concentrates. However, they face challenges connected with m…
