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…

Fragmentation of Virtual Orbitals for Quantum Computing: Reducing Qubit Requirements through Many-Body Expansion

Federico Zahariev, Vassiliki-Alexandra Glezakou, Mark S. Gordon

We introduce quantum virtual-orbital fragmentation (Q-FVO), a systematic method for reducing the largest active space in correlated quantum-chemistry calculations. The complete occ…

Quantum Simulation Programming via Typing

Liyi Li, Federico Zahariev, Chandeepa Dissanayake +3

Quantum simulations are designed to model quantum systems, and many compilation frameworks have been developed for executing such simulations on quantum computers. Most compilers l…

Nodal Variational Principle for Excited States

Federico Zahariev, Mark S. Gordon, Mel Levy

It is proven that the exact excited-state wave function and energy may be obtained by minimizing the energy expectation value of trial wave functions that are constrained only to h…
