Ultrafast chemical reactions are difficult to simulate because they involve entangled, many-body wavefunctions whose computational complexity grows rapidly with molecular size. In photochemistry, the breakdown of Born-Oppenheimer approximation further complicates problem by entangling nuclear and electronic degrees freedom. Here, we show that analog quantum simulators can efficiently dynamics u...

Presented is a quantum lattice gas for Navier-Stokes fluid dynamics simulation. The quantum lattice-gas transport equation at the microscopic scale is presented as a generalization of the classical lattice-gas transport equation. A special type of quantum computer network is proposed that is suitable for implementing the quantum lattice gas. The quantum computer network undergoes a partial coll...

The trapped-ion system has been a leading platform for practical quantum computation and simulation since the first scheme of gate was proposed by Cirac Zoller in 1995. Quantum gates with trapped ions have shown highest fidelity among all physical platforms. Recently, sophisticated schemes such as amplitude, phase, frequency modulation, or multi-frequency application, developed to make fast, ro...

Dissipative collective effects are ubiquitous in quantum physics, and their relevance ranges from the study of entanglement biological systems to noise mitigation computers. Here, we put forward first fully simulation dissipative phenomena on a real computer, based recently introduced multipartite collision model. First, theoretically accuracy this algorithm near-term computers with noisy gates...

Abstract The rapid development in hardware for quantum computing and simulation has led to much interest problems where these devices can exceed the capabilities of existing classical computers known methods. Approaching this that go beyond testing performance a device is an important step, many-body quench dynamics one most promising candidates early practical advantage. We analyse requirement...

For the prediction of the device performance of FinFET structures three-dimensional device simulation is inevitable. Due to the strong quantum mechanical confinement in the channel, quantum correction models need to be applied. Two of these models, where one is based on the correction of the densityof-states in a pre-processing step and the other calculates a correction for the band edge energy...
