Geometry-Dependent Nonlocal Valence Screening Following Core Ionization of the Water Dimer
Vibin Abraham, Bo Peng
Core ionization is spatially localized, but the correlated valence response that screens the resulting hole need not be. Using the water dimer as a minimal hydrogen-bonded system,…
Unified Uncertainty Quantification Framework Bridging Noisy Quantum Backends Across Variational Quantum Algorithms and Quantum Signal Processing
Priyabrata Senapati, Vibin Abraham, Qiang Guan +1
The paper introduces a unified uncertainty quantification framework that benchmarks noisy quantum processors using both variational quantum algorithms and quantum signal processing…
Near-limit quantum control beyond analytic tractability in many-body spin systems
Jixing Zhang, Bo Peng, Yang Wang +11
As quantum control approaches hardware-imposed performance limits, weak effects omitted by reduced models become consequential. Assumptions required for analytic tractability then…
Chemically decisive benchmarks on the path to quantum utility
Srivathsan Poyyapakkam Sundar, Vibin Abraham, Bo Peng +1
Progress towards quantum utility in chemistry requires not only algorithmic advances, but also the identification of chemically meaningful problems whose electronic structure funda…
Elucidating Many-Body Effects in Molecular Core Spectra through Real-Time Approaches: Efficient Classical Approximations and a Quantum Perspective
Vibin Abraham, Priyabrata Senapati, Himadri Pathak +1
Accurately resolving many-body satellite features in molecular core-level spectra requires theoretical approaches that capture electron correlation both efficiently and systematica…
