Scientists observe an effect in the quantum world that does not exist in the macrocosm.

Researchers at the University of Bonn and ETH Zurich have conducted an in-depth study of unique phase transitions in certain metals. Their findings provide a better understanding of quantum physics and potentially advance the field of quantum information technology.

When they are cooled below a certain critical temperature, many substances change their properties. For example, such a phase transition occurs, when water freezes. However, in certain metals, there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature’s smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions.

In the fascinating landscape tech realm, quantum computing stock opportunities could prove to be incredibly lucrative over time. The notion of quantum computing, born over two decades ago, is now gaining solid traction on The Street. Moreover, the technology, rooted in the mysteries of quantum mechanics, aims to boost computing speeds significantly.

The advancements in quantum computing are impossible to ignore, with continuous improvements and decreasing development costs. Moreover, the sector’s convergence with cloud computing opens doors for broader accessibility among researchers and software developers.

Furthermore, as the digital economy and artificial intelligence sectors grow, global spending on cloud computing is expected to reach a whopping $1 trillion annually within the next decade. Quantum computing appears to be on the cusp of becoming a game-changer, and it might be the most opportune time to load up on affordable quantum computing stocks.

Detecting the permanent imprints left by colliding black holes would reveal a universe saturated with infinite symmetries – and narrow the possibilities for a theory of quantum gravity.

Quantum entanglement is one of the most intriguing and perplexing phenomena in quantum physics. It allows physicists to create connections between particles that seem to violate our understanding of space and time.

This video discusses what quantum entanglement really is, and the experiments that help us understand it. The results of these experiments have applications in new technologies that will forever change our world.

Inside of a black hole, the two theoretical pillars of 20th-century physics appear to clash. Now a group of young physicists think they have resolved the conflict by appealing to the central pillar of the new century — the physics of quantum information.

McKinsey and Company is no stranger to generative artificial intelligence (gen AI): around half of the global consulting giant’s employees were said to be using the technology as of earlier this summer.

But it’s not the only org to see a rapid uptake of gen AI. Indeed, a new annual report by McKinsey’s AI arm QuantumBlack finds that “use of gen AI is already widespread.”

Optical phase retrieval and imaging appear in a wide variety of science fields, such as imaging of quasi-transparent biological samples or nanostructures metrological characterization, for example, in the semiconductor industry. At a fundamental level, the limit to imaging accuracy in classical systems comes from the intrinsic fluctuation of the illuminating light, since the photons that form it are emitted randomly by conventional sources and behave independently of one another.

Quantum correlation in light beams, in which photons show certain cooperation, can surpass those limits. Although quantum advantage obtained in phase estimation through first-order interference is well understood, interferometric schemes are not suitable for multi-parameter wide-field imaging, requiring raster scanning for extended samples.

In a new paper published in Light Science & Application, a team of scientists from the Quantum Optics Group of the Italian National Metrology Institute (INRiM), Italy, and from the Imaging Physics Dept. Optics Research Group, Faculty of Applied Sciences of Delft University of Technology, The Netherlands, has developed a technology exploiting quantum correlations to enhance imaging of phase profiles in a non-interferometric way.
