The defect-free assembly of 2-D clusters with over 100 single-atom quantum systems

Researchers at Technische Universität Darmstadt have recently demonstrated the defect-free assembly of versatile target patterns of up to 111 single-atom quantum systems. Their findings, outlined in a paper published in Physical Review Letters, could drive assembled-atom architectures beyond the threshold of quantum advantage, paving the way for new breakthroughs in quantum science and technology.

Organic laser diodes move from dream to reality

Researchers from Japan have demonstrated that a long-elusive kind of laser diode based on organic semiconductors is indeed possible, paving the way for the further expansion of lasers in applications such as biosensing, displays, healthcare and optical communications.

Experiments and calculations allow examination of boron's complicated dance

Work opens a path to precise calculations of the structure of other nuclei.

Experiments and calculations allow examination of boron's complicated dance

In a study that combines groundbreaking experimental work and theoretical calculations, researchers have determined the nuclear geometry of two isotopes of boron. The result could help open a path to precise calculations of the structure of other nuclei that scientists could experimentally validate.

Physicists 'teleport' logic operation between separated ions

Physicists have teleported a computer circuit instruction known as a quantum logic operation between two separated ions (electrically charged atoms), showcasing how quantum computer programs could carry out tasks in future large-scale quantum networks.

The most complete study of battery failure sees the light

An international team of researchers just published the widest study on what happens during battery failure, focusing on the different parts of a battery at the same time.

Thermal analog black hole agrees with Hawking radiation theory

A team of researchers at the Israel Institute of Technology has found that a thermal analog black hole they created agrees with the Hawking radiation theory. In their paper published in the journal Nature, the group describes building their analog black hole and using data from it to test its temperature. Silke Weinfurtner with the University of Nottingham has published a News and Views piece on the work done by the team in the same journal issue.

Stabilizing the no-boundary proposal sheds light on the universe's quantum origins

One idea for how the universe began is that the universe may have appeared out of nothing due to some quantum effect, such as quantum tunneling. In the 1980s, Stephen Hawking and James Hartle further elaborated on this idea by suggesting that time did not exist before the beginning of the universe, leading them to conclude that the universe has no initial boundary conditions on either time or space. The idea is called the "no-boundary proposal" or the "Hawking-Hartle state."

More than a spring-clean for LHC magnets

In April, work began on one of the major projects scheduled for the second long shutdown (LS2) of the CERN accelerators: improving the electrical insulation of over 1200 magnets in the Large Hadron Collider (LHC). To complete this mammoth task, more than 150 people are hard at work in the LHC tunnel... and they will be there for over a year.

Beyond 1 and 0: Engineers boost potential for creating successor to shrinking transistors

Scientists offer a solution to the fast-approaching physical minimum for transistor size: a multi-value logic transistor based on zinc oxide, capable of two stable intermediate states between 0 and 1.
