Among the many computational challenges faced across different disciplines, quantum-
mechanical systems pose some of the hardest ones and offer a natural playground for the …

Electron transport in realistic physical and chemical systems often involves the nontrivial
exchange of energy with a large environment, requiring the definition and treatment of open …

Quantum systems are inherently open and susceptible to environmental noise, which can
have both detrimental and beneficial effects on their dynamics. This phenomenon has been …

Accurate simulation of the time evolution of a quantum system under the influence of an
environment is critical to making accurate predictions in chemistry, condensed-matter …

Realizing nonunitary transformations on unitary-gate-based quantum devices is critically
important for simulating a variety of physical problems, including open quantum systems and …

Perturbation theory, used in a wide range of fields, is a powerful tool for approximate
solutions to complex problems, starting from the exact solution of a related, simpler problem …

We propose and demonstrate a unified hierarchical method to measure n-point correlation
functions that can be applied to driven, dissipative, or otherwise open or nonequilibrium …

Green's function methods lead to ab initio, systematically improvable simulations of
molecules and materials while providing access to multiple experimentally observable …

We show that current noisy quantum computers are ideal platforms for the simulation of
quantum many-body dynamics in generic open systems. We demonstrate this using the IBM …

In this paper we present a quantum algorithm that uses noise as a resource. The goal of our
quantum algorithm is the calculation of operator averages of an open quantum system …
