A new method for the production of protonated hydrogen

A research group led by Prof. Matthias Kling of the Max Planck Institute for Quantum Optics (MPQ) and the Ludwig-Maximilian University in Munich (LMU), in cooperation with the American University in Sharjah, has discovered ...

Nuclear physicists on the hunt for squeezed protons

While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own. Observing these squeezed protons may offer unique insights ...

Error-protected quantum bits entangled for the first time

For the first time, physicists from the University of Innsbruck have entangled two quantum bits distributed over several quantum objects and successfully transmitted their quantum properties. This marks an important milestone ...

Researchers question fundamental study on the Kondo effect

The Kondo effect influences the electrical resistance of metals at low temperatures and generates complex electronic and magnetic orders. Novel concepts for data storage and processing, such as using quantum dots, are based ...

Multiparty entanglement: When everything is connected

Entanglement is an ubiquitous concept in modern physics research: it occurs in subjects ranging from quantum gravity to quantum computing. In a publication that appeared in Physical Review Letters last week, UvA-IoP physicist ...

Explaining gravity without string theory

For decades, most physicists have agreed that string theory is the missing link between Einstein's theory of general relativity, describing the laws of nature at the largest scale, and quantum mechanics, describing them at ...

Controlling the electron spin: Flip it quickly but carefully

Over the past two decades, a new area at the interface of semiconductor physics, electronics and quantum mechanics has been gaining popularity among theoretical physicists and experimenters. This new field is called spintronics, ...
