Beyond Orbital Rotations: Correlation-Rank Limits and Clifford-Accessible Measurement, from Algebra and Global Optimization
Federico Zahariev, Vanda Glezakou
One should not assume that reconstructing an electronic observable with a smaller set of measurement settings will cut the number of repetitions in proportion. Each setting is simp…

Certified Bounds on the Measurement Cost of Molecular Hamiltonians
Federico Zahariev, Vanda Glezakou
Quantum estimates of molecular energy require repeated state preparation and measurement. We bound the minimum repetition count for given measurements and processing rules from abo…
