Optimally Weighted Constrained Shadow Tomography for Reduced Density Matrices
Yuchen Wang, Irma Avdic, Michael Rose +7
Accurate measurement of reduced density matrices (RDMs) is central to quantum simulations of many-fermion systems, but the required measurement resources remain a significant chall…
Size-Consistent Quantum Chemistry on Quantum Computers
Noah Garrett, Michael Rose, David A. Mazziotti
Hybrid quantum-classical algorithms have begun to leverage quantum devices to efficiently represent many-electron wavefunctions, enabling early demonstrations of molecular simulati…
Many-Body Time Evolution from a Correlation-Efficient Quantum Algorithm
Michael Rose, David A. Mazziotti
We introduce the correlation-efficient time-evolution (CETE) algorithm for simulating quantum many-body dynamics. CETE recasts each step of time evolution as a time-independent cor…
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…
