The implementation of time-evolution operators U(t), called Hamiltonian simulation, is one the most promising usage quantum computers. For time-independent Hamiltonians, qubitization has recently established efficient realizati...

Environmental theoretical calculation aims to use computer simulation assist in solving environmental problems. Herein, we present the guiding principles of for non-periodic systems. A summary is given recent progress towards reveal degradation/transformation mechanisms contaminants reactions. ‘Beyond experiment’ has been gradually accepted as a general concept chemistry discipline. As and scie...

Low-rank iterative methods of periodic projected Lyapunov equations and their application in model reduction of periodic descriptor systems Low-rank iterative methods of periodic projected Lyapunov equations and their application in model reduction of periodic descriptor systems Abstract We discuss the numerical solution of large-scale sparse projected discrete-time periodic Lyapunov equations ...
