WebJun 18, 2024 · Random unitary dynamical evolutions play an important role in characterizing quantum Markovianity. By exploiting the maximally entangled state under the representation of a set of generalized unitary Weyl operators, we present a necessary and sufficient condition for quantum Markovianity in d-level systems from the … Web2 days ago · Subsequently, we resolve the quantum brachistochrone problem by achieving the time-optimal evolution. By restricting the whole system to a two spin-$1/2$ system, we investigate the relevant entanglement from two viewpoints; The first is of geometric nature and explores how the entanglement level affects derived geometric structures such as …
WebApplying the tools The so-called ‘evolution rule’ in dynamical system theory is largely deterministic, meaning that for a specific period of time only, one future state follows the current state. However, some systems are more chaotic in that random external events can actually influence the outcome within systems.
