Using machine-learning and an integrated photonic chip, researchers from INRS (Canada) and the University of Sussex (UK) can now customize the properties of broadband light sources. Also called “supercontinuum”, these sources are at the core of new imaging technologies and the approach proposed by the researchers will bring further insight into fundamental aspects of light-matter […]
Reshaping Energy Landscape of Phonons in Nanocrystals
Phonons, which are packets of vibrational waves that propagate in solids, play a key role in condensed matter and are involved in various physical properties of materials. In nanotechnology, for example, they affect light emission and charge transport of nanodevices. As the main source of energy dissipation in solid-state systems, phonons are the ultimate bottleneck […]

The Multi-Colored Photons That Might Change Quantum Information Science
With leading corporations now investing in highly expensive and complex infrastructures to unleash the power of quantum technologies, INRS researchers have achieved a breakthrough in a light-weight photonic system created using on-chip devices and off-the-shelf telecommunications components. In their paper published in Nature, the team demonstrates that photons can become an accessible and powerful quantum resource […]
Giant Step Forward In Generating Optical Qubits
The optical chip developed at INRS by Prof. Roberto Morandotti’s team overcomes a number of obstacles in the development of quantum computers, which are expected to revolutionize information processing. The international research team has demonstrated that on-chip quantum frequency combs can be used to simultaneously generate multiphoton entangled quantum bit (qubit) states. Quantum computing differs […]
Could We Control the Path of Lightning?
Lightning dart across the sky in a flash. And even though we can use lightning rods to increase the probability of it striking at a specific location, its exact path remains unpredictable. At a smaller scale, discharges between two electrodes behave in the same manner, streaking through space to create electric arcs where only the […]
