Light meets superconducting circuits
Light meets superconducting circuits
Researchers have developed a light-based approach to read out superconducting circuits, overcoming the scaling-up limitations of quantum computing systems. In the last few years, several technology companies including Google, Microsoft, and IBM, have massively invested in quantum computing systems based on microwave superconducting circuit platforms in an effort to scale them up from small research-oriented systems to commercialized computing platforms.

Cell cytoskeleton as target for new active agents
Through a unique combination of computer simulations and laboratory experiments, researchers at the Paul Scherrer Institute PSI have discovered new binding sites for active agents - against cancer, for example - on a vital protein of the cell cytoskeleton. Eleven of the sites hadn't been known before.

A material-keyboard made of graphene
Researchers at ETH Zurich have succeeded in turning specially prepared graphene flakes either into insulators or into superconductors by applying an electric voltage. This technique even works locally, meaning that in the same graphene flake regions with completely different physical properties can be realized side by side.

A physics perspective on wound healing
A physics perspective on wound healing
Scientists from the University of Geneva and UZH have used a statistical physics approach to identify the lengthscales of key intercellular interactions which govern tissue healing. In material physics understanding how systems interact across the interfaces separating them is of central interest. But can physical models clarify similar concepts in living systems, such as cells?

The shape of light changes our vision
The shape of light changes our vision
Scientists at the UNIGE have shown that the response of the retina to light depends not only on the intensity of the light perceived by the eye, but also on its temporal shape and the order in which the colours are organized. Vision is a complex process that has been successfully deciphered by many disciplines -physics, biochemistry, physiology, neurology, etc.-: The retina captures light, the optic nerve transmits electrical impulses to the brain, which ultimately generates the perception of an image.

Quantum steering for more precise measurements
Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University of Basel has now proposed a new scheme for such measurements that uses a particular kind of correlation between quantum particles. In quantum information, the fictitious agents Alice and Bob are often used to illustrate complex communication tasks.

Eliminating resistant bacteria with nanoparticles
Eliminating resistant bacteria with nanoparticles
Novel nanoparticles developed by researchers at ETH Zurich and Empa detect multi-resistant bacteria hiding in body cells and kill them. The scientists' goal is to develop an antibacterial agent that is effective where conventional antibiotics remain ineffective. In the arms race "mankind against bacteria", bacteria are currently ahead of us.

New tech builds ultralow-loss integrated photonic circuits
Scientists have developed ultralow-loss silicon nitride integrated circuits that are central for many photonic devices, such as chip-scale frequency combs, narrow-linewidth lasers, coherent LiDAR, and neuromorphic computing. Encoding information into light, and transmitting it through optical fibers lies at the core of optical communications.

Water and quantum magnets share critical physics
Water can freeze from liquid to solid ice or boil into a gas. In the kitchen these "phase transitions" aren't smooth, but their discontinuous nature is smoothed out at high pressure. An international team of physicists led by EPFL has now discovered the same behavior in certain quantum magnets, which may have consequences for the technology of qubits.

Hint for new particles
Hint for new particles
The US research laboratory "Fermilab" has published the eagerly awaited results of the experimental measurement of the so-called anomalous magnetic dipole moment of the muon. As members of the "Muon g-2 Theory Initiative", researchers from the University of Bern have calculated the same physical quantity theoretically in parallel, based on the Standard Model.

Artificial intelligence to explore the biomolecular world
Scientists have developed AI-powered nanosensors that let researchers track various kinds of biological molecules without disturbing them. The tiny world of biomolecules is rich in fascinating interactions between a plethora of different agents such as intricate nanomachines (proteins), shape-shifting vessels (lipid complexes), chains of vital information (DNA) and energy fuel (carbohydrates).

Two strange planets
Two strange planets
Uranus and Neptune both have a completely skewed magnetic field, perhaps due to the planets- special inner structures. But new experiments by ETH researchers now show that the mystery remains unsolved. The two large gas planets Uranus and Neptune have strange magnetic fields. These are each strongly tilted relative to the planet's rotation axes and are significantly offset from the physical centre of the planet.

ALPHA cools antimatter using laser light for the first time
Geneva, 31 March 2021. The ALPHA collaboration at CERN has succeeded in cooling down antihydrogen atoms - the simplest form of atomic antimatter - using laser light. The technique, known as laser cooling, was first demonstrated 40 years ago on normal matter and is a mainstay of many research fields.

New nanotransistors keep their cool at high voltages
Power converters play an essential role in electric vehicles and solar panels, for example, but tend to lose a lot of power in the form of heat in the electricity conversion process. Thanks to a new type of transistor developed at EPFL, these converters can perform at substantially improved efficiencies, especially in high-power applications.

The skeleton of the malaria parasite reveals its secrets
The skeleton of the malaria parasite reveals its secrets
Research teams from UNIGE have discovered that the cytoskeleton of the malaria parasite comprises a vestigial form of an organelle called conoid, initially thought to be absent from this species and which could play a role in host invasion. Plasmodium is the parasite causing malaria, one of the deadliest parasitic diseases.
