Success by deception

Theoretical physicists from ETH Zurich deliberately misled intelligent machines, and thus refined the process of machine learning. They created a new method that allows computers to categorise data – even when humans have no idea what this categorisation might look like. Read more

Taming complexity

Quantum systems consisting of many particles are a major challenge for physicists, since their behaviour can be determined only with immense computational power. ETH physicists have now discovered an elegant way to simplify the problem. Read more

Gaming in the name of science

Quantum mechanics can be entertaining: anyone with a few minutes to spare for a video game on 30 November can do their bit to help solve a fundamental question of physics that was once argued over by Albert Einstein and Nils Bohr. ETH Professor Andreas Wallraff explains what the Big Bell Test is all about. Read more

At the frontier of quantum physics

The ETH Zurich Latsis Prize 2016 goes to ETH physics professor Jonathan Home. He studies the frontier between quantum and classical physics using individual charged atoms that he controls with high precision. Read more

Hot on the heels of quasiparticles

Electrons in a solid can team up to form so-called quasiparticles, which lead to new phenomena. Physicists at ETH in Zurich have now studied previously unidentified quasiparticles in a new class of atomically thin semiconductors. The researchers use their results to correct a prevailing misinterpretation. Read more

Metal in chains

The electronic energy states allowed by quantum mechanics determine whether a solid is an insulator or whether it conducts electric current as a metal. Researchers at ETH have now theoretically predicted a novel material whose energy states exhibit a hitherto unknown peculiarity. Read more

Eight professors appointed at ETH Zurich

Upon application of ETH President Lino Guzzella the ETH Board appointed a total of eight professors and awarded the title of professor to one individual. Read more

First creation of huge quantum states with oscillating ions

For years physicists have strived to control the quantum states of atoms or molecules very accurately. Researchers at ETH Zurich have now established a record for the size of  quantum states generated with massive particles. Their technique could be used to make quantum computers faster. Read more

Three-way battles in the quantum world

In phase transitions, for instance between water and water vapour, the motional energy competes with the attractive energy between neighbouring molecules. Physicists at ETH Zurich have now studied quantum phase transitions in which distant particles also influence one another. Read more

Faster entanglement of distant quantum dots

Entanglement between distant quantum objects is an important ingredient for future information technologies. Researchers at the ETH have now developed a method with which such states can be created a thousand times faster than before. Read more

Surprising discovery of a new particle

Studying peculiar properties of a long known metallic material researchers have chanced upon a new particle. It is related to the so-called Weyl fermions that the mathematician Hermann Weyl predicted almost ninety years ago. Weyl had overlooked the particle, which could have interesting applications in electronics. Read more

A resonator for electrons

Resonators are an important tool in physics. The curved mirrors inside the resonators usually focus light waves that act, for instance, on atoms. Physicists at ETH Zurich have now managed to build a resonator for electrons and to direct the standing waves thus created onto an artificial atom. Read more

Soundproofing with quantum physics

Sebastian Huber and his colleagues show that the road from abstract theory to practical applications needn’t always be very long. Their mechanical implementation of a quantum mechanical phenomenon could soon be used for soundproofing purposes. Read more

Squeezed quantum cats

ETH professor Jonathan Home and his colleagues reach deep into their bag of tricks to create so-called “squeezed Schrödinger cats”. These quantum systems could be extremely useful for future technologies. Read more

Giving it her all in both athletics and science

Bettina Heim has succeeded in publishing the results of her semester project in one of the most prestigious scientific journals. Heim was able to show why in certain tests current quantum computing devices were no faster than conventional computers, contrary to previous assumptions. ETH News met the former top athlete and now successful scientist. Read more

A quantum channel made of light

In experiments using ultracold atoms and laser light, ETH researchers have measured a stepwise change in conductivity as the atoms pass through tiny structures. This is the first time that this quantum effect has been observed for electrically neutral particles. Read more

Quantum computing machine under scrutiny

A new and innovative computing machine is currently attracting a great deal of attention in specialist circles. A team under the leadership of Matthias Troyer, a professor at ETH Zurich, has now confirmed that the machine uses quantum effects. However, it is not any faster than a traditional computer.
