Since its discovery, quantum entanglement has challenged some of the best established
views of the world: locality and reality. Quantum technologies promise to revolutionize …

Twisted photons can be used as alphabets to encode information beyond one bit per single
photon. This ability offers great potential for quantum information tasks, as well as for the …

Graphs have provided an expressive mathematical tool to model quantum-mechanical
devices and systems. In particular, it has been recently discovered that graph theory can be …

Most quantum computers use binary encoding to store information in qubits—the quantum
analogue of classical bits. Yet, the underlying physical hardware consists of information …

Entanglement is an important resource for quantum technologies. There are many ways
quantum systems can be entangled, ranging from the two-qubit case to entanglement in …

How useful can machine learning be in a quantum laboratory? Here we raise the question of
the potential of intelligent machines in the context of scientific research. A major motivation …

Noise can be considered the natural enemy of quantum information. An often implied benefit
of high-dimensional entanglement is its increased resilience to noise. However, manifesting …

Forming the backbone of quantum technologies today, entanglement, has been
demonstrated in physical systems as diverse as photons, ions and superconducting circuits …

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 …

Quantum mechanics predicts a number of, at first sight, counterintuitive phenomena. It
therefore remains a question whether our intuition is the best way to find new experiments …
