Quantum error-correcting codes were developed by mathematicians to check the variability of the state of each qubit. But are the codes relevant in practical terms? A physicist at IRIG investigated the issue and his conclusions are not optimistic. He noted that the theories use error models that fail to factor in errors that are rare, […] >>

Researchers from LMGP and Leti tested OLEDs developed by Leti for microdisplays for toxicity to determine whether the OLEDs could be used in biological environments. The researchers monitored the growth of two cultures (one cellular and one bacterial) in which an OLED had been placed and compared growth to control cultures. They found that the […] >>

Imagine 3D printing antennas and connections between components or sensors directly onto plastic enclosures or other plastic parts. LGP2* and IMEP-LaHC are working on just that in PhD research being conducted under an industrial excellence chair. The research is focusing on the development of industrial processes, functional (conductive, resistive, nanoparticle-based, etc.) inks, and annealing methods […] >>

Researchers from Leti successfully integrated a high-performance chemical sensor on silicon. The system’s quantum cascade lasers, photoacoustic cell, and photonic circuit take up less than 1 cm3; the conventional system originally took up around a liter. The lasers produce light in the mid-infrared spectrum, which means that they can detect a broad range of gases. […] >>

In mid-May Leti presented a promising micro-LED fabrication technology at a conference in the United States. The technology would make it possible to fabricate micro-LEDs at a very low cost and transfer the LEDs onto all types of substrates—rigid, flexible, transparent, or opaque—with no limits on size. In the future, consumers could even order custom […] >>
