Researchers at ETH Zurich have developed a method that uses a single ion to detect electromagnetic fields above a surface and ...

"Traditionally, Penning traps are used when one wants to trap very many ions for precision experiments, but without having to control them individually," says Ph.D. student Shreyans Jain. "By contrast ...

Researchers at ETH Zurich have developed a technique that uses a single trapped ion ...

A new technique uses a single trapped ion to create detailed maps of electromagnetic fields, helping researchers identify ...

Trapped ion quantum computing noise hit a 30-year wall until ETH Zurich researchers built a Penning-trap scanner using a ...

Trapping ions with static magnetic and electric fields instead of an oscillating electromagnetic field could make it easier to use ions as building blocks for quantum computers. The new approach, ...

A two-stage trap for single protons leads to measurement of their magnetic properties with unprecedented precision Using the double Penning trap, Ulmer and his colleagues cycled an individual proton ...

One of the biggest riddles in physics is the apparent imbalance between matter and antimatter in our universe. To date, there is no explanation as to why matter and antimatter failed to completely ...

The most precise measurements of the atomic masses of the proton and the electron make use of Penning traps, and for the latter, a hydrogen-like ion, as Edmund Myers explains. Improvements in Penning ...

Researchers at CERN have created and trapped antihydrogen in an attempt to study the underpinnings of the standard model of physics. Antihydrogen is made of antiparticles, specifically an antiproton ...

The energy states of electrons in an atom follow the laws of quantum mechanics: they are not continuously distributed but restricted to certain well- defined values – this is also called quantisation.
