Recently, it was demonstrated that the distribution of these quantum states can also exhibit universal …
WebApr 21, 2024 · Recent experiments began to explore the topological properties of quench dynamics, i.e., the time evolution following a sudden change in the Hamiltonian, via tomography of quantum gases in optical lattices. WebJun 25, 2024 · The time evolving quantum state is read out by state tomography. Evidence of dynamical quantum phase transitions, such as paths of time evolution states on the Bloch sphere, non-analytic behavior of the dynamical free energy and the emergence of Skyrmion lattice in momentum-time space, is observed.
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 ... WebMar 12, 2024 · The article establishes a framework for dynamic generation of informationally complete POVMs in quantum state tomography. Assuming that the evolution of a quantum system is given by a dynamical map in the Kraus representation, one can switch to the Heisenberg picture and define the measurements in the time domain.
