This topical review addresses how Rydberg atoms can serve as building blocks for
emerging quantum technologies. Whereas the fabrication of large numbers of artificial …

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

Currently, perovskite solar cells (PSCs) with high performances greater than 20% contain
bromine (Br), causing a suboptimal bandgap, and the thermally unstable methylammonium …

Rydberg atoms with principal quantum number n⪢ 1 have exaggerated atomic properties
including dipole-dipole interactions that scale as n 4 and radiative lifetimes that scale as n 3 …

Optical photons are powerful carriers of quantum information, which can be delivered in free
space by satellites or in fibers on the ground over long distances. Entanglement of quantum …

This review summarizes experimental works performed over the last decade by several
groups on the manipulation of a few individual interacting Rydberg atoms. These studies …

Tailored quantum states of light can be created via a transfer of collective quantum states of
matter to light modes. Such collective quantum states emerge in interacting many-body …

Blockade interactions whereby a single particle prevents the flow or excitation of other
particles provide a mechanism for control of quantum states, including entanglement of two …

Compared to other types of qubits, photon is one of a kind due to its unparalleled
advantages in long-distance quantum information exchange. Therefore, photon is a natural …

Metasurfaces mould the flow of classical light waves by engineering subwavelength patterns
from dielectric or metallic thin films. We introduce and analyse a method in which quantum …
