WebMar 31, 2024 · In this article. Quantum mechanics is largely the study of quantum dynamics, which seeks to understand how an initial quantum state $\ket{\psi(0)}$ varies over time (see the conceptual docs on quantum computing for more info on Dirac notation). Specifically, given this initial condition a quantum state, an evolution time and a … Webwork [1] it was shown how a general dynamical system can be mapped directly into quantum dynamical systems via a method called Schr¨odingerisation – i.e., turning a non-Schr¨odinger equation into systems of Schr¨odinger’s equations. ... evolution of a state y for a long enough (discrete) time so the state approaches the steady state, i.e ...

In particular, in ... Webglobal stationary state, which is an eigenstate of the to-tal Hamiltonian with zero energy eigenvalue. Dynamical evolution arises from this static state as a result of the quantum entanglement between the degree of freedom of an appropriate subsystem C, called the clock, and the rest of the Universe R. According to this idea, time and
