Witnessing Entanglement in Mixed-Particle Quantum Systems
Irma Avdic, David A. Mazziotti
We introduce an entanglement witness that identifies off-diagonal long-range order (ODLRO) -- a distinctive form of entanglement -- in systems containing both fermionic and bosonic…
Entanglement Witnesses of Condensation for Enhanced Quantum Sensing
Lillian I. Payne Torres, Irma Avdic, Anna O. Schouten +3
Quantum phenomena such as entanglement provide powerful resources for enhancing classical sensing. Here, we theoretically show that collective entanglement of spin qubits, arising…
Correlated Purification for Restoring -Representability in Quantum Simulation
Yuchen Wang, Irma Avdic, Michael Rose +4
Classical shadow tomography offers a scalable route to estimating properties of quantum states, but the resulting reduced density matrices (RDMs) often violate constraints that ens…
Constrained Shadow Tomography for Molecular Simulation on Quantum Devices
Irma Avdic, Yuchen Wang, Michael Rose +4
Quantum state tomography is a fundamental task in quantum information science, enabling detailed characterization of correlations, entanglement, and electronic structure in quantum…
Refining ensemble -representability of one-body density matrices from partial information
Julia Liebert, Anna O. Schouten, Irma Avdic +2
The -representability problem places fundamental constraints on reduced density matrices (RDMs) that originate from physical many-fermion quantum states. Motivated by recent dev…
Characterizing conical intersections of nucleobases on quantum computers
Yuchen Wang, Cameron Cianci, Irma Avdic +7
Hybrid quantum-classical computing algorithms offer significant potential for accelerating the calculation of the electronic structure of strongly correlated molecules. In this wor…
Shadow Ansatz for the Many-Fermion Wave Function in Scalable Molecular Simulations on Quantum Computing Devices
Yuchen Wang, Irma Avdic, David A. Mazziotti
Here we show that shadow tomography can generate an efficient and exact ansatz for the many-fermion wave function on quantum devices. We derive the shadow ansatz -- a product of tr…
Enhanced Shadow Tomography of Molecular Excited States from Enforcing -representability Conditions by Semidefinite Programming
Irma Avdic, David A. Mazziotti
Excited-state properties of highly correlated systems are key to understanding photosynthesis, luminescence, and the development of novel optical materials, but accurately capturin…
Quantum Algorithms and Applications for Open Quantum Systems
Luis H. Delgado-Granados, Timothy J. Krogmeier, LeeAnn M. Sager-Smith +10
Accurate models for open quantum systems -- quantum states that have non-trivial interactions with their environment -- may aid in the advancement of a diverse array of fields, inc…
Fewer measurements from shadow tomography with -representability conditions
Irma Avdic, David A. Mazziotti
Classical shadow tomography provides a randomized scheme for approximating the quantum state and its properties at reduced computational cost with applications in quantum computing…
