A Review On Quantum Computing | PDF | Quantum Mechanics | Quantum Computing Quantum algorithms for simulating electronic ground states are slower than popular classical mean field algorithms such as hartree–fock and density functional theory but offer higher accuracy. Building on the close relationship between the unraveled lindblad dynamics, stochastic magnus integrators, and variational quantum simulation, we propose a high order scheme for solving the quantum state diffusion equation using exponential integrators. Researchers at rice university have made a meaningful advance in the simulation of molecular electron transfer—a fundamental process underpinning countless physical, chemical and biological. We analyze the query complexity of these algorithms and perform numerical experiments to demonstrate the validity of this approach. this helps to bridge the gap between available quantum algorithms and computational models for quantum dynamics in unbounded domains.

Simulating the dynamics of complex quantum systems is a central application of quantum devices. here we propose leveraging the power of measurements to simulate short time quantum dynamics of physically prepared quantum states in classical postprocessing using a truncated taylor series approach. At a glance: pasqal is a spinout from the institut d’optique, france, building “quantum processing units” made of neutral atoms in large 2d and 3d arrays for computing and simulation of quantum systems. We introduce a hybrid algorithm that utilizes a quantum computer for simulating the field induced quantum dynamics of a molecular system in polynomial time, in combination with a classical optimization approach for updating the field. We show how these features manifest through examples of quantum simulation of dirac dynamics, which is relevant to the study of both high energy physics and 2d materials.
