Silicon Photonics, the technology where optical devices are fabricated by the mainstream
microelectronic processing technology, was proposed almost 30 years ago. I joined this …

We revisit the interaction of a first-quantized atomic system (consisting of two charged
quantum particles) with the quantum electromagnetic field, pointing out the subtleties related …

Quantum coherence plays a fundamental role in the study and control of ultrafast dynamics
in matter. In the case of photoionization, entanglement of the photoelectron with the ion is a …

Quantum walks have proven to be a universal model for quantum computation and to
provide speed-up in certain quantum algorithms. The discrete-time quantum walk (DTQW) …

Frustration and quantum entanglement are two exotic quantum properties in quantum many-
body systems. However, despite several efforts, an exact relationship between them remains …

Quantum entanglement represents an ideal resource to guarantee the security of random
numbers employed in many scientific and cryptographic applications. However …

An open challenge in physics is to expand the frontiers of the validity of quantum mechanics
by evidencing nonclassicality of the center of mass state of a macroscopic object. Yet …

The possibility of achieving and controlling scalable classically entangled, ie, inseparable,
multipartite states, would fundamentally challenge the advantages of quantum systems in …

A bstract Entanglement is assuming a central role in modern quantum many-body physics.
Yet, for lattice gauge theories its certification remains extremely challenging. A key difficulty …

Maximally entangled single-particle states (MESPS) are opening new possibilities in
quantum technology, as they have the potential to encode more information and are robust …
