Abstract
I introduce the recent advancements of single atom physics and technology in silicon devices. Single atom-based devices display a rich variety of physical phenomena ranging from quantum transport to control of single electrons, to Kondo effect and single photon emission. I review technological issues and future prospects in the field of quantum computing and quantum communications, including the most recent research of room temperature single photon regime from Er emission.

7th International Workshop on Photoluminescence in Rare Earths (PRE'17): Photonic Materials and Devices
November 30 - December 2, 2017 | Rome, Italy

PRE’17 is the seventh event in the series of International Workshops covering a wide range of research topics concerning the properties and applications of rare-earth ions in optoelectronics and photonics. The series begun in Trento, Italy in May 2005 (PRE’05), followed by PRE’07 again in Trento, PRE’10 in Firenze (Italy), PRE’12 in Kyoto (Japan), PRE’14 in San Sebastián (Spain), PRE’16 in Greenville (USA). The next event, after the decision to move the Workshop to the odd years, will be held in Rome, Italy, at the end of 2017.

More than 600 scientists and students from more than 30 countries, in total, have attended the previous Workshops. The average size of each event, around 100 people, makes for a collegial environment where students and world experts can mingle and talk in an informal and effective way.

Over the past decade, an increasing number of luminescent materials have been reported, based on the properties of rare earth ions embedded in different matrices (crystalline, amorphous and glass ceramics; oxides, fluorides, chalcogenides, organics, ….) or contained in molecular complexes.
These materials have already been been widely employed in light sources and amplifiers, optical displays, fluorescent probes, luminescent labels, frequency converters, detectors, and so on, thus covering fields ranging from telecommunication to sensing, from medical diagnosis to energy. Despite of it, there are still increasing demands for novel functions to further extend their practical applications.

This PRE Workshop, like the previous ones, aims at providing a forum for material scientists, chemists and physicists where to debate about the state of the art and the perspectives of the photonic materials based on rare earth ions. Both fundamental photoluminescence properties and application oriented material investigations will be considered.
We would like to welcome all the interested experts from different countries in the world to PRE’17, which will be held on November 30 - December 2, 2017 in one of the most ancient and beautiful cities in the world: Roma.

Realizzati per la prima volta circuiti fotonici in diamante per computer quantistici in grado di fornire una potenza di calcolo infinitamente superiore rispetto ai pc tradizionali. Lo studio internazionale, coordinato congiuntamente dall’Ifn-Cnr e dal Dipartimento di fisica del Politecnico di Milano, è pubblicato su Nature Scientific Reports. Gli innovativi strumenti consentirebbero di risolvere problemi dall’elevata complessità di calcolo come le previsioni dei cambiamenti climatici o le variazioni del mercato azionario e troverebbero impiego anche nella diagnostica medica.

Spectral sHapIng For biomedial and energy applicaTions
Tenerife, Canary Islands, Spain
November, 13-17, 2017

Important dates
Abstract submission: open from december 2016

Spectral shaping of light is an emerging route for enhancing the efficiency of various solar energy harvesting, storage and conversion processes facing the increasing demand for energy supply, from photovoltaics to photocatalysis, natural and artificial photosynthesis and solar fuels generation, where usually large parts of the solar spectrum are not efficiently utilized. Moreover the use of light in life sciences, within the well-known infrared therapeutic windows (deeper penetration and lower tissue damage) and subsequent wavelength transformation to higher or lower energies provides ground-breaking applications in photodynamic cancer therapy and bio-imaging. Interdisciplinary efforts from physics, chemistry, biology, medicine, materials science and engineering will certainly be required to overcome current challenges leading the way for spectral shaping of light to be a future key technology.

"SHIFT 2017" International Conference shows up as a cutting-edge multidisciplinary platform to gather presentations and discussions of recent achievements by leading researchers in wavelength shifting luminescence processes (quantum cutting, down-shifting, up–conversion...), as a very promising and not yet fully explored route.

Join us in warm and sunny Tenerife (Canary Islands) in November 2017 to make a significant shift to state-of-the art spectral shaping for biomedical and energy applications.

The SHIFT happens in Tenerife!
