A Quantum Algorithm for Simulating Nonunitary Dynamics Governed by Nonautonomous Linear Ordinary Differential Equations
Pouya Khazaei, Eitan Geva
Nonautonomous linear ordinary differential equations of the form , where is non-skew-symmetric, are often used to describe nonunitary dynamics in a…
The Quantum Transition State
Pouya Khazaei
For nearly a century, the transition state---the structure organizing motion between reactants and products---has seemed to lack an exact quantum counterpart. Its geometry---a recr…
Cavity-Modified Nonequilibrium Fermi's Golden Rule Rate Coefficients from Cavity-Free Inputs
Pouya Khazaei, Eitan Geva
The Nonequilibrium Fermi's Golden Rule (NE-FGR) provides a convenient theoretical framework for calculating the charge transfer rate between a photoexcited bright donor electronic…
A Roadmap for Simulating Chemical Dynamics on a Parametrically Driven Bosonic Quantum Device
Delmar G. A. Cabral, Pouya Khazaei, Brandon C. Allen +8
Chemical reactions are commonly described by the reactive flux transferring population from reactants to products across a double-well free energy barrier. Dynamics often involves…
Asymmetry Control in a Parametric Oscillator for the Quantum Simulation of Chemical Activation
Alejandro Cros Carrillo de Albornoz, Rodrigo G. Cortiñas, Max Schäfer +8
Dissipative tunneling remains a cornerstone effect in quantum mechanics. In chemistry, it plays a crucial role in governing the rates of chemical reactions, often modeled as the mo…
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…
