Development of a new type of optical receiver, able to restore chaotic signals in free-space optical communication links distorted by atmospheric turbulence. By use of a system of optical antennas integrated into a programmable photonic chip, the receiver can adapt in real time, maintaining the integrity of the signal even in harsh atmospheric conditions. The study by a team of researchers led by Télécom Paris and the Politecnico di Milano, has just been published in Light: Science & Applications, and paves the way for the use of chaos-based encryption for secure, high-speed communication in hostile environments.

Imagining a future where we can monitor the health of the planet's forests and crops with millimetre precision is no longer science fiction. This is the objective of INTERSEN, a project included in the 2021 State Research Plan and led by the Visual Engineering (eViS) research group at the Universitat Jaume I in Castelló, which is committed to the intelligent combination of spatial data to improve the way we understand and care for our environment.

What if humanity's search for life on other planets returns no hits? An international team of researchers, led by ETH Zurich's Institute for Particle Physics and Astrophysics studied what insights can be gained from a 'no life detected' scenario in future exoplanet surveys.

This paper reports the discovery of a high-velocity star J07 ejected from globular cluster M15 approximately 21 million years ago, providing strong evidence for the presence of an IMBH constrained to within a few AU of the central region of M15.

The Technion researchers revealed the process that photons undergo from the stage in which they are introduced into the nanoscale system until they exit the measurement system, and found that this transition enriches the space of states that the photons can reside in. In a series of measurements, the researchers mapped those states, entangled them with the same property unique to nanoscale systems, and confirmed the correspondence between photon pairs that indicates quantum entanglement.

This is the first discovery of a new quantum entanglement in more than 20 years, and it may lead in the future to the development of new tools for the design of photon-based quantum communication and computing components, as well as to their significant miniaturization.
