In recent years, quantum computing has made significant strides, particularly in light-based
technology. The introduction of quantum photonic chips has ushered in an era marked by …

The theory of the beam splitter (BS) in quantum optics is well developed and based on fairly
simple mathematical and physical foundations. This theory has been developed for any type …

Quantum metrology takes advantage of nonclassical resources such as entanglement to
achieve a sensitivity level below the standard quantum limit. To date, almost all quantum …

We consider the distribution of secret keys, both in a bipartite and a multipartite (conference)
setting, via a quantum network and establish a framework to obtain bounds on the …

Artificial intelligence (AI) is a potentially disruptive tool for physics and science in general.
One crucial question is how this technology can contribute at a conceptual level to help …

Following the emergence of quantum computing, the subsequent quantum revolution will be
that of interconnecting individual quantum computers at the global level. In the same way …

Randomized benchmarking (RB) is the most commonly employed protocol for the
characterization of unitary operations in quantum circuits due to its reasonable experimental …

It is well known that a beam splitter (BS) can be used as a source of photon quantum
entanglement. This is due to the fact that the statistics of photons changes at the output ports …

The concept of quantum computing has evolved over nearly a century to a point now where
it is no longer science-fiction. However, conceptual extensions of quantum computation and …

Interferometers provide a highly sensitive means to investigate and exploit the coherence
properties of light in metrology applications. However, interferometers come in various forms …
