Quantum correlations between two parties are essential for the argument of Einstein,
Podolsky, and Rosen in favor of the incompleteness of quantum mechanics. Schrödinger …

A few decades ago, quantum optics stood out as a new domain of physics by exhibiting
states of light with no classical equivalent. The first investigations concerned single photons …

Einstein-Rosen-Podolsky (EPR) steering or quantum steering describes the “spooky action
at a distance” that one party is able to remotely alter the states of the other if they share a …

Nonlinear magnonics studies the nonlinear interaction between magnons and other
physical platforms (phonon, photon, qubit, spin texture) to generate novel magnon states for …

The need for secrecy and security is essential in communication. Secret sharing is a
conventional protocol to distribute a secret message to a group of parties, who cannot …

Understanding how quantum resources can be quantified and distributed over many parties
has profound applications in quantum communication. As one of the most intriguing features …

We show how to implement stationary one-way quantum steering with strong entanglement
in a cavity magnonic system that consists of two magnon modes and a microwave cavity …

We develop a general framework to assess capabilities and limitations of the Gaussian
toolbox in continuous-variable quantum information theory. Our framework allows us to …

As two valuable quantum resources, Einstein-Podolsky-Rosen entanglement and steering
play important roles in quantum-enhanced communication protocols. Distributing such …

The excitation of toroidal multipoles in metamaterials is investigated for a high-Q response at
a subwavelength scale. In this paper, we explore the optimization of toroidal excitations in a …
