Optical technology can slash the energy required by AI
Research
EPFL
EPFL engineers are pioneering an energy-saving technology that uses fiber optics to boost the performance of supercomputers.
Why do we need sharper weather and climate models?
Research
ETH Zurich
We know that CO2 is warming the planet. But if we want to understand its consequences and avert risks, more accurate weather and climate models are crucial, says Nicolas Gruber.
New, high-resolution models merge weather and climate
Research
ETH Zurich Empa
Torrential rain and flooding have dominated the weather over the past few weeks. To forecast these weather events with greater accuracy and gain a better understanding of them against the backdrop of global climate change, ETH Zurich and partners are developing a new generation of high-resolution weather and climate models.
Running quantum software on a classical computer
Research
EPFL
Two physicists, from EPFL and Columbia University, have introduced an approach for simulating the quantum approximate optimization algorithm using a traditional computer. Instead of running the algorithm on advanced quantum processors, the new approach uses a classical machine-learning algorithm that closely mimics the behavior of near-term quantum computers.
Four cryptographic vulnerabilities in Telegram
Research
ETH Zurich
An international research team of cryptographers completed a detailed security analysis of the popular Telegram messaging platform identifying several weaknesses in its protocol that demonstrate the product falls short of some essential data security guarantees.
Nanosphere at the quantum limit
Research
ETH Zurich
Researchers at ETH Zurich have trapped a tiny sphere measuring a hundred nanometres using laser light and slowed down its motion to the lowest quantum mechanical state. Based on this, one can study quantum effects in macroscopic objects and build extremely sensitive sensors.
