In part two of the interview marking the 100th anniversary of quantum mechanics, ETH Professor Klaus Ensslin explains why quantum technology is developing at such a rapid pace at the moment and why Switzerland needs to make an effort if it doesn’t want to be left behind. 

Three quantum researchers were presented with the Nobel Prize in Stockholm on 10 December. Meanwhile, this year marked the centenary of quantum mechanics as a field of research. In this two-part interview, ETH Professor Klaus Ensslin looks back at its beginnings and talks about where the technology is headed. 

Ursula Keller, Professor of Physics at ETH Zurich, will deliver her farewell lecture on Monday, 15 December 2025. Her talk, entitled “Ultrafast science: a 32-year journey in Physics at ETH Zurich,” marks the close of more than three decades at the forefront of ultrafast laser science – a field she helped build from the ground up. 

An international collaboration released new constraints on the value of the Hubble constant based on the study of strongly lensed quasars.

At its meeting of 3 and 4 December 2025 and upon application of Joël Mesot, President of ETH Zurich, the ETH Board appointed eleven professors. In addition, seven adjunct professorships were awarded.

As particle physicists envision the future of their discipline, one point is clear: there's much potential for exploration and discovery beyond the Standard Model.

Sascha Quanz was awarded the Golden Owl for his teaching activities in the Department of Physics. Every year, the ETH Zurich Student Association (VSETH) honours lecturers whose excellent teaching stands out with this award.

There is much less water on the surfaces of distant planets outside our solar system than previously thought. These exoplanets do not have thick layers of water, as was often speculated. That’s the conclusion of an international study led by ETH Zurich. 

Nine researchers from ETH Zurich have just been awarded Starting Grants from the European Research Council (ERC). This is a positive signal for Zurich as a research location.
