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…
