The distribution of quantum states over long distances is limited by photon loss.
Straightforward amplification as in classical telecommunications is not an option in quantum …

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

Cat states, with their unique phase-space interference properties, are ideal candidates for
understanding fundamental principles of quantum mechanics and performing key quantum …

Superpositions of macroscopically distinct quantum states, introduced in Schrödinger's
famous Gedankenexperiment, are an epitome of quantum 'strangeness' and a natural tool …

The wave–particle duality of light has led to two different encodings for optical quantum
information processing. Several approaches have emerged based either on particle-like …

Schrödinger's cat originates from the famous thought experiment querying the
counterintuitive quantum superposition of macroscopic objects. As a natural extension …

We review entangled coherent state research since its first implicit use in 1967 to the
present. Entangled coherent states are important to quantum superselection principles …

We propose and experimentally realize a novel versatile protocol that allows the quantum
state engineering of heralded optical coherent-state superpositions. This scheme relies on a …

This review covers recent theoretical and experimental efforts to extend the application of
the continuous-variable quantum technology of light beyond" Gaussian" quantum states …

A quantum memory for light is a key element for the realization of future quantum information
networks,,. Requirements for a good quantum memory are versatility (allowing a wide range …
