THE (DARK) MINIONS

The "Almighty" Technician 

Picture
ANTONIO MIRIAMETRO

I am an electronic technician at the Department of Physics of the University of Rome "La Sapienza". I love my job, I like analog and digital electronics (preferably the digital one), as well as computer science. My duties are a technical collaboration with new projects and maintenance of electronic instrumentation. Specializing in L.A.S.E.R systems. From 1993 to 2001, I have participated in seven Antarctic campaigns, as electronic manager at O.A.S.I. (Submillimetric Infrared Antarctic Observatory) at the Italian base "Baia Terra Nova" (now "Mario Zucchelli" 74 ° 41 '42 "South and 164 ° 05 '58" East). My last Antarctic campaign has been in 2007 at the Dome Concordia Station (75°07'S 123°22'E) on the Antarctic plateau at 3250 meters above s.l. for the COCHISE project (Cosmological Observations at Concordia with High-sensitivity Instrument for Source Extraction).

FRANCESCO BASSO BASSET

I received the B.S. and M.S. degrees in Physics from the University of Milan in 2014 and the Ph.D. degree in Materials Science and Nanotechnology in 2018 from the University of Milano-Bicocca. During my PhD, I worked in the Laboratory of Semiconductor Spectroscopy in active collaboration with the interuniversity center L-NESS and the Johannes Kepler University in Linz (8-month research period abroad). My research interests include optical spectroscopy, semiconductor nanotechnology, and quantum optics. I currently focus on designing and performing experiments in quantum information to further develop semiconductor nanostructures as on-demand quantum emitters.

EMANUELE ROCCIA

I am currently pursuing the post-doctoral carrier at the Nanophotonics group located at “La Sapienza” University of Rome. After receiving the Bachelor’s and Master’s degree at “La Sapienza” University of Rome in 2012 and 2015, respectively, I obtained the PhD degree in Science of Matter, Nanotechnology and Complex Systems in 2019 at “Università degli Studi Roma Tre”, Rome. During my PhD I explored the spectral correlation effect on the two-photon emission process on the Spontaneous Parametric Down-Conversion event exploiting the benefits of Quantum Metrology. At the moment, my research activity intent is to investigate quantum communication protocols with the use of semiconductor quantum dot as entangled photon-pair emitter.
