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,…

The cost of quantum algorithms for biochemistry: A case study in metaphosphate hydrolysis
Ryan LaRose, Antonios M. Alvertis, Alan Bidart +10
We evaluate the quantum resource requirements for ATP/metaphosphate hydrolysis, one of the most important reactions in all of biology with implications for metabolism, cellular sig…

Measurement reduction for expectation values via fine-grained commutativity
Ben DalFavero, Rahul Sarkar, Jeremiah Rowland +3
We introduce a notion of commutativity between operators on a tensor product space, nominally Pauli strings on qubits, that interpolates between qubit-wise commutativity and (full)…
