Universality of Quantum Gates in Particle and Symmetry Constrained Subspaces
Andreas Stergiou, Nicolas PD Sawaya
Simulating physical systems on near-term quantum computers often requires preparing states within constrained subspaces, like those with fixed particle number or spin. We use Lie a…

Overlapped groupings for quantum energy estimation: Maximal variance reduction and deterministic algorithms for reducing variance
Jeremiah Rowland, Rahul Sarkar, Nicolas PD Sawaya +2
Grouping-based measurement strategies are widely used to reduce measurement complexity in near-term quantum algorithms. While these schemes have typically produced disjoint groups,…

HamLib: A library of Hamiltonians for benchmarking quantum algorithms and hardware
Nicolas PD Sawaya, Daniel Marti-Dafcik, Yang Ho +13
In order to characterize and benchmark computational hardware, software, and algorithms, it is essential to have many problem instances on-hand. This is no less true for quantum co…
