DESCRIPTION:[b]Quantum Timekeeping\, a simple story of atoms and photons\,
  by Davide Calonico\, Scientific Director of INRIM[/b][b] [/b]\n\n[b]Abou
 t the lecture[/b]\nHow an Atomic clock is able to beat with an attosecond
  precision? May clocks measure tides? What time is it on the Moon? How ca
 n we stop and cool atoms with lasers? Is the definition of the unit of ti
 me the second still satisfactory? These questions\, and many more\, conce
 rn one of the most precise quantum technologies developed by humankind\, 
 the exploitation of the quantum structure of atoms with atomic clocks. In
  the lecture\, we will illustrate the fundamentals of atomic timekeeping\
 , following the key advances in science and technology that led to presen
 t accuracy of one attosecond. As well we will describe how precise clocks
  contribute to science and modern society\, from testing the standard mod
 el of particles to general relativity\, from pervasive technologies like 
 satellite navigation and telecommunication to timestamping of financial t
 ransition. We will talk a bit on modern laser cooling techniques\, the po
 ssibility of using nuclear clocks\, the miniaturization of clocks with na
 notechnologies and last\, we will discuss the roadmap towards the new def
 inition of the unit of time in the International System of Units in the C
 onvention of the meter\, in a journey embracing the last 70 years of our 
 everyday life. Last\, the roadmap of the redefinition will bring us to to
 uch other quantum technologies: the relevance of coherent interferometry 
 on optical fibers\, hence the possibility to have time and quantum commun
 ication on the same optical fiber\, enabling infrastructures like the Ita
 lian Quantum Backbone and the European Quantum Communication Infrastructu
 re (EuroQCI).\n\n[b]About the speaker[/b]\nDavide Calonico is the Scienti
 fic Director of INRIM\, Istituto Nazionale di Ricerca Metrologica\, an It
 alian Public Research Institute that is also the Italian Institute of Met
 rology in the convention of the Metre.  DDC is a physicist expert in prim
 ary metrology and quantum technologies. Its main scientific achievements 
 are in atomic clocks\, sensing\, and quantum communication over fiber. DC
  coordinates the Italian Quantum backbone\, that realizes in Italy the Eu
 ropean Quantum Communication Infrastructure of the European Commission. H
 e is the scientific responsible for INRIM of the infrastructure Piquet\, 
 Piemonte Quantum Enabling Technology\, devoted in INRIM to metrology on a
  chip. He developed several atomic clocks based on laser-cooled atoms lik
 e Cesium Rubidium\, Ytterbium\, and Strontium\, and microstructured clock
 s based on nanotechnologies\n\n[i]The event is organized by [/i][i][url=h
