Spintronics and quantum information science are two promising candidates for innovating
information processing technologies. The combination of these two fields enables us to build …

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

The magnon cat state represents a macroscopic quantum superposition of collective
magnetic excitations of large number spins that not only provides fundamental tests of …

Gaussian states have played an important role in the physics of continuous-variable
quantum systems. They are appealing for the experimental ease with which they can be …

Quantum steering refers to the non-classical correlations that can be observed between the
outcomes of measurements applied on half of an entangled state and the resulting post …

Steering is the entanglement-based quantum effect that embodies the “spooky action at a
distance” disliked by Einstein and scrutinized by Einstein, Podolsky, and Rosen. Here we …

We investigate the resources needed for secure teleportation of coherent states. We extend
continuous variable teleportation to include quantum teleamplification protocols that allow …

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 …

We present an operational framework for Einstein-Podolsky-Rosen steering as a physical
resource. For arbitrary-dimensional bipartite systems composed of a quantum subsystem …

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