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…
Quantum Simulation of Bosons with the Contracted Quantum Eigensolver
Yuchen Wang, LeeAnn M. Sager-Smith, David A. Mazziotti
Quantum computers are promising tools for simulating many-body quantum systems due to their potential scaling advantage over classical computers. While significant effort has been…
Quantum Phase Transitions in a Model Hamiltonian Exhibiting Entangled Simultaneous Fermion-Pair and Exciton Condensations
Samuel Warren, LeeAnn M. Sager-Smith, David A. Mazziotti
Quantum states of a novel Bose-Einstein condensate, in which both fermion-pair and exciton condensations are simultaneously present, have recently been realized theoretically in a…
Quantum Simulation of Quantum Phase Transitions Using the Convex Geometry of Reduced Density Matrices
Samuel Warren, LeeAnn M. Sager-Smith, David A. Mazziotti
Transitions of many-particle quantum systems between distinct phases at absolute-zero temperature, known as quantum phase transitions, require an exacting treatment of particle cor…
Quantum Simulation of Open Quantum Systems Using Density-Matrix Purification
Anthony W. Schlimgen, Kade Head-Marsden, LeeAnn M. Sager-Smith +2
Electronic structure and transport in realistically-sized systems often require an open quantum system (OQS) treatment, where the system is defined in the context of an environment…
Quantum State Preparation and Non-Unitary Evolution with Diagonal Operators
Anthony W. Schlimgen, Kade Head-Marsden, LeeAnn M. Sager-Smith +2
Realizing non-unitary transformations on unitary-gate based quantum devices is critically important for simulating a variety of physical problems including open quantum systems and…
