It has been theoretically demonstrated that two spins (qubits or qutrits), coupled by exchange interaction only, undergo a coupling-based joint Landau-Majorana-Stuckelberg-Zener (LMSZ) transition when a linear ramp acts upon one of the two spins. Such a transition, under appropriate conditions on the parameters, drives the two-spin system toward a maximally entangled state. In this paper, effects on the quantum dynamics of the two qudits, stemming from the Dzyaloshinskii-Moriya (DM) and dipole…

Symmetry-Induced Emergence of a Pseudo-Qutrit in the Dipolar Coupling of Two Qubits
We investigate a system of two identical and distinguishable spins 1/2, with a direct magnetic dipole–dipole interaction, in an external magnetic field. Constraining the hyperfine tensor to exhibit
Two-Qubit Entanglement Generation through Non-Hermitian Hamiltonians Induced by Repeated Measurements on an Ancilla
This paper demonstrates the effectiveness of a proposed protocol for engineering non-Hermitian Hamiltonians as a result of repetitive measurements on an ancillary qubit by applying it to physically relevant multi-spin models, and reports a new recipe to construct a physical scenario where the quantum dynamics of a physical system represented by a given non- herMITian Hamiltonian model may be simulated.


Coupling-assisted Landau-Majorana-Stückelberg-Zener transition in a system of two interacting spin qubits
We analyse a system of two interacting spin-qubits subjected to a Landau-Majorana-St\"uckelberg-Zener (LMSZ) ramp. We prove that LMSZ transitions of the two spin-qubits are possible without an
Landau-Majorana-Stückelberg-Zener dynamics driven by coupling for two interacting qutrit systems
A time-dependent two interacting spin-qutrit model is analysed and solved. The two interacting qutrits are subjected to a longitudinal field linearly varying over time as in the
