Thirty years after it was first proposed, quantum teleportation remains one of the most
important protocols in quantum information and quantum technologies, enabling the …

Research in quantum information processing has followed two different directions: the use of
discrete variables (qubits) and that of high-dimensional, continuous-variable Gaussian …

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 …

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

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

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 …

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 …

We present an entanglement purification protocol (EPP) to reconstruct some maximally
hybrid entangled states (HESs) from nonmaximally mixed HESs. We use simple linear …

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