Quantum information processing based on Rydberg atoms emerged as a promising
direction two decades ago. Recent experimental and theoretical progresses have shined …

We propose a physical realization of quantum cellular automata (QCA) using arrays of
ultracold atoms excited to Rydberg states. The key ingredient is the use of programmable …

While the Rydberg-blockade regime provides the natural setting for creating W-type
entanglement with cold neutral atoms, it is demonstrated here that a scalable entanglement …

Motivated by the significantly improved scalability of optically trapped neutral-atom systems,
extensive efforts have been devoted in recent years to quantum-state engineering in …

Using the quantum-brachistochrone formalism, we address the problem of finding the fastest
possible (time-optimal) deterministic conversion between W and Greenberger-Horne …

Robust edge transport can occur when charged particles in crystalline lattices interact with
an applied external magnetic field. Such systems have a spectrum composed of bands of …

We investigate the possibilities for a deterministic conversion between two important types of
maximally entangled multiqubit states, namely, W and Greenberger-Horne-Zeilinger (GHZ) …

We introduce a discrete-time quantum dynamics on a two-dimensional lattice that describes
the evolution of a 1+ 1-dimensional spin system. The underlying quantum map is …

Studying dynamics is one of the most challenging areas of quantum many-body physics. In
recent years, an attractive platform based on Rydberg atoms has been used to probe it since …

The multipartite GHZ states are useful resources for quantum information processing. Here
we put forward a scalable way to adiabatically prepare the multipartite GHZ states in a chain …
