In contrast to classical systems, actual implementation of non-Hermitian Hamiltonian dynamics for quantum systems is a challenge because the processes of energy gain and dissipation are based on the underlying Hermitian system–environment dynamics, which are trace preserving. Recently, a scheme for engineering non-Hermitian Hamiltonians as a result of repetitive measurements on an ancillary qubit has been proposed. The induced conditional dynamics of the main system is described by the…

Multipartite Correlations in Quantum Collision Models
Quantum collision models have proved to be useful for a clear and concise description of many physical phenomena in the field of open quantum systems: thermalization, decoherence, homogenization,
Spin‐Chain‐Star Systems: Entangling Multiple Chains of Spin Qubits
We consider spin‐chain‐star systems characterized by N‐wise many‐body interactions between the spins in each chain and the central one. We show that such systems can be exactly mapped into standard
Greenberger‐Horne‐Zeilinger‐state Generation in Qubit‐Chains via a Single Landau‐Majorana‐Stückelberg‐Zener π/2‐pulse
A protocol for generating Greenberger‐Horne‐Zeilinger states in a system of N$N$ coupled qubits is proposed. The Hamiltonian model assumes N$N$ ‐wise interactions between the N$N$ qubits and the
Entropic Uncertainty for Two Coupled Dipole Spins Using Quantum Memory under the Dzyaloshinskii–Moriya Interaction
The results reveal that the model parameters cause significant variations in the predicted QMA-EUR, and the entropy mixedness can be a proper indicator of the nature of the entropic uncertainty.
Entanglement Robustness in Trace Decreasing Quantum Dynamics
Trace decreasing dynamical maps are as physical as trace preserving ones; however, they are much less studied. Here we overview how the quantum Sinkhorn theorem can be successfully applied to find a
Trace decreasing quantum dynamical maps: Divisibility and entanglement dynamics
Trace decreasing quantum operations naturally emerge in experiments involving postselection. However, the experiments usually focus on dynamics of the conditional output states as if the dynamics

Nonlinear optics.
In this method, non-linear susceptibility tensors are introduced which relate the induced dipole moment to a power series expansion in field strengths and the various experimental observations are described and interpreted in terms of this formalism.
The word "symmetry" is used in mathematics quite differently from in ordinary speech. In everyday life one applies it mainly to two-sided, right-left symmetry; but not so in mathematics. Admittedly,
