WebApr 12, 2024 · Download PDF Abstract: We discuss the interconnections between basic correlation measures of a bipartite quantum state and basic information characteristics of a quantum channel, focusing on the benefits of these interconnections for solving specific problems concerning the characteristics of both types. We describe the basic properties … WebQuantum optical Gaussian states are a type of important robust quantum states which are manipulatable by the existing technologies. … Extending the existing results of quantum … WebWe show how to exploit a variational ansatz based on non-Gaussian wavefunctions for fast non-adiabatic preparation of quantum many-body states using quantum optimal control. We demonstrate this on the example of spin-boson model, where we determine the optimal time variation of the Hamiltonian parameters to prepare (near) critical ground states in times, … cough and lisinopril side effects
