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…
Unitary Dynamics for Open Quantum Systems with Density-Matrix Purification
Luis H. Delgado-Granados, Samuel Warren, David A. Mazziotti
Accurate modeling of quantum systems interacting with environments requires addressing non-unitary dynamics, which significantly complicates computational approaches. In this work,…
Simulating Chemistry on Bosonic Quantum Devices
Rishab Dutta, Delmar G. A. Cabral, Ningyi Lyu +23
Bosonic quantum devices offer a novel approach to realize quantum computations, where the quantum two-level system (qubit) is replaced with the quantum (an)harmonic oscillator (qum…
