Quantum systems do not fail silently; they fall in the blink of an eye. In less time than it takes light to travel through a virus, a carefully ordered quantum state can break down, losing the coherence that makes quantum technology so powerful. For many years, this rapid separation occurs within one to two femtoseconds … Read more
Dark matter is thought to be ubiquitous, surrounding galaxies and helping to create the largest objects in the universe. But no one knows what it is made of. Now, a new theoretical study presents a unique and surprising scenario that may provide some of the missing pieces of the puzzle. Some of the dark matter … Read more
Stephen Hawking showed in the 1970s that black holes are not completely black. They slowly emit radiation and shrink over time, eventually disappearing. However, there was a problem with this explanation. If a black hole evaporates completely, what happens to all the information about the matter it has absorbed? Quantum physics says that information cannot … Read more
astronomers have discovered a third galaxy that does not contain dark matter, challenging conventional wisdom about the mysterious substance believed to hold galaxies together. Published in a new study available in pre-print on arXiv, this discovery of NGC 1052-DF9 adds weight to the strong theory of the “Bullet Dwarf” collision, which suggests that galaxies can … Read more
Astronomers have captured the longest gamma ray burst ever observed, a seven-hour burst of intense light from a black hole devouring a companion star. The event, called GRB 250702B, lasted about 25,000 seconds, breaking the previous record of 15,000 seconds and forcing scientists to rethink how the most powerful explosions in the universe work. Gamma … Read more
For many years, the development of artificial intelligence has followed a simple rule: make it bigger with more groups, more connections, more computing power. However, a new study suggests otherwise. Instead of going big, the study’s authors built a very small object – a quantum system with nine spins interacting with an atom – and … Read more
A game with only three moves may sound simple. In quantum physics, it can still break old logic. That is the focus of a new experiment led by physicist Zhenghao Liu and his colleagues at the Technical University of Denmark. Writing in Science Advances, the team has constructed what they describe as the Greenberger-Horne-Zeilinger triple … Read more
Physicists have created a very precise and very complex atomic clock based on ytterbium, which can test the limits of the Standard Model and even search for invisible dark matter. Led by Taiki Ishiyama, PhD, a physicist at Kyoto University’s School of Science in Japan, the project used the unusual orbital change of atoms, which … Read more
IBM’s unveiling of two new supercomputers and Denmark’s plans to develop “the world’s most powerful business computer” mark just two of the latest developments in quantum technology’s rapid transition from experimental success to practical applications. There is growing promise of quantum technology’s ability to solve problems that today’s systems struggle to overcome or can’t even … Read more
The ever-present hail of cosmic rays streaming into the Solar System from an outer galaxy may not be what we thought. According to Chang’e 4 on the far side of the Moon, there is a mysterious ‘bag’ of cosmic ray flux between the Earth and the Moon that occurs when the two bodies line up … Read more
