We study the complexity of both time-optimal and time sub-optimal quantum Hamiltonian
evolutions connecting arbitrary source and a target states on the Bloch sphere equipped …

We study a generic time-dependent Jaynes–Cummings model, discovering universal
features of its time evolution on a dynamical time scale which is here defined as an integral …

Two-level quantum systems are fundamental physical models that continue to attract
growing interest due to their crucial role as a building block of quantum technologies. The …

Eigenstate preparation is ubiquitous in quantum computing, and a standard approach for
generating the lowest-energy states of a given system is by employing adiabatic state …

It is known that the Frenet-Serret apparatus of a space curve in three-dimensional Euclidean
space determines the local geometry of curves. In particular, the Frenet-Serret apparatus …

Two coupled two-level systems placed under external time-dependent magnetic fields are
modeled by a general Hamiltonian endowed with a symmetry that enables us to reduce the …

A protocol for generating Greenberger‐Horne‐Zeilinger states in a system of NN coupled
qubits is proposed. The Hamiltonian model assumes NN‐wise interactions between the NN …

The exact quantum dynamics of a single spin‐1/2 in a generic time‐dependent classical
magnetic field are investigated and compared with the quantum motion of a spin‐1/2 studied …

In the geometry of quantum-mechanical processes, the time-varying curvature coefficient of
a quantum evolution is specified by the magnitude squared of the covariant derivative of the …

It has been theoretically demonstrated that two spins (qubits or qutrits), coupled by
exchange interaction only, undergo a coupling-based joint Landau-Majorana-Stückelberg …
