“In a semiconductor, electrons can be excited by absorbing laser light. Advances during the past decade enabled measuring this fundamental physical mechanism on timescales below a femtosecond (10-15 s). ETH physicists now for the first time resolved the response of …
“The electric energy system is becoming increasingly diverse and distributed. This trend is bound to have an impact on how the system operators will control and optimize the future grid, blogs Gabriela Hug. Optimizing the electrical power grid has always …
“An international collaboration led by ETH physicists has used machine learning to teach a computer how to predict the outcomes of quantum experiments. The results could prove to be essential for testing future quantum computers. Physics students spend many years …
“In a world in which we use devices that we do not necessarily trust, can there be any privacy? Yes, and that’s precisely what device-independent quantum cryptography achieves. New work now shows how this ‘ultimate’ level of communication security …
“ETH Zurich students are learning about self-driving vehicles using a model with a fleet of mini-taxis. As part of the Duckietown course, they are working together with students in Montreal and Chicago on problems that concern developers of self-driving cars …
“Experiments based on atoms in a shaken artificial crystal made of light offer novel insight into the physics of quantum many-body systems — which might help in the development of future data-storage technologies. The speed of writing and reading out magnetic …
“ETH physicists have developed a silicon wafer that behaves like a topological insulator when stimulated using ultrasound. They have thereby succeeded in turning an abstract theoretical concept into a macroscopic product. The usual procedure goes like this: you have a …
“A type of quantum dot that has been intensively studied in recent years can reproduce light in every colour and is very bright. An international research team that includes scientists from ETH Zurich has now discovered why this is the …
“When symmetries in quantum systems are spontaneously broken, the collective excitation modes change in characteristic ways. Researchers at ETH have now directly observed such Goldstone and Higgs modes for the first time. A cylindrical rod is rotationally symmetric – after any …
“Transistors capable of functioning with an electrical current consisting of the passage of a single electron at each point in time are on the horizon for research in the field of information technology. By associating the 0/1 binary with …
