A Breakthrough in Optical Physics by Professor Roberto Morandotti’s Team

January 6, 2017

Update : November 16, 2020

For the second year in a row, a scientific advance by Professor Roberto Morandotti’s team at the INRS Énergie Matériaux Télécommunications Research Centre has been chosen as one of the top ten discoveries of 2016 by Québec Science. Quantum computing is one step closer to becoming a reality thanks to the team’s breakthrough in optical physics.  

Using an optical frequency comb, researchers were able to simultaneously generate multiphoton entangled quantum bit (qubit) states—a historic first. In doing so, they showed that it is possible to generate a wide range of complex quantum states for optical communication in signal processing and spectroscopy.
The discovery is also compatible with current electronics. This represents a significant advantage, spurring Professor Morandotti to predict in the Québec Science article that the computer of tomorrow will be a hybrid that combines the characteristics of present day computers and those of quantum computers, with their vastly superior computing power. 
The breakthrough was made in INRS’s ultra high speed light manipulation laboratory (LULMAN) and has been met with keen interest from the international scientific community. It also garnered the attention of prestigious media such as Science Daily, Science, and Optics and Photonics News (the “Optics in 2016” special issue), to name a few.  
Researchers Christian Reimer, Michael Kues, Piotr Roztocki, Benjamin Wetzel, Fabio Grazioso, Brent E. Little, Sai T. Chu, Tudor Johnston, Yaron Bromberg, Lucia Caspani, David J. Moss, and Roberto Morandotti presented their results in the March 2016 issue of Science in an article entitled “Generation of multiphoton entangled quantum states by means of integrated frequency combs” (DOI: 10.1126/science.aad8532).
