In both classical and quantum many-body physics, it is a core issue to characterize statistical
correlations among different degrees of freedom. From this point of view, a natural question …

The many-body physics at quantum phase transitions shows a subtle interplay between
quantum and thermal fluctuations, emerging in the low-temperature limit. In this review, we …

Matter-wave interference experiments provide a direct confirmation of the quantum
superposition principle, a hallmark of quantum theory, and thereby constrain possible …

Abstract Greenberger-Horne-Zeilinger (GHZ) states, also known as two-component
Schrödinger cats, play vital roles in the foundation of quantum physics and the potential …

Quantum teleportation, the faithful transfer of an unknown input state onto a remote quantum
system, is a key component in long-distance quantum communication protocols and …

The Stern-Gerlach effect, found a century ago, has become a paradigm of quantum
mechanics. Unexpectedly, until recently, there has been little evidence that the original …

A fundamental question in the field of polaritonic chemistry is whether collective coupling
implies local modifications of chemical properties scaling with the ensemble size. Here we …

We present a scheme to entangle the vibrational phonon modes of two massive
ferromagnetic spheres in a dual-cavity magnomechanical system. In each cavity, a …

Multi‐wavelength quantum light sources are extremely desired in establishing
communication links among multiple users for realizing quantum networks. Despite recent …

This Perspective provides a brief introduction into the theoretical complexity of polaritonic
chemistry, which emerges from the hybrid nature of strongly coupled light–matter states. To …
