Once, holograms were just a scientific curiosity. But thanks to the rapid development of lasers, they have gradually moved center stage, appearing on the security imagery for credit cards and bank notes, in science fiction movies—most memorably Star Wars—and even “live” on stage when long-dead rapper Tupac reincarnated for fans at the Coachella music festival in 2012. …

Quantum leap for speed limit bounds
Nature’s speed limits aren’t posted on road signs, but Rice University physicists have discovered a new way to deduce them that is better—infinitely better, in some cases—than previous methods. …
Tiny bubbles make a quantum leap
July 13, 2020—Researchers at Columbia Engineering and Montana State University report today that they have found that placing sufficient strain in a 2-D material—tungsten diselenide (WSe2)—creates localized states that can yield single-photon emitters. Using sophisticated optical microscopy techniques developed at Columbia over the past three years, the team was able to directly image these states for the first time, revealing that…
Successfully measuring infinitesimal change in mass of individual atoms for the first time
A new door to the quantum world has been opened: When an atom absorbs or releases energy via the quantum leap of an electron, it becomes heavier or lighter. This can be explained by Einstein’s theory of relativity (E = mc2). However, the effect is minuscule for a single atom. Nevertheless, the team of Klaus Blaum and Sergey Eliseev at the…
Heat can quantum leap across a totally empty vacuum
Even a total vacuum is full of strange quantum fluctuations, which have now been caught making heat leap across empty space for the first time Source: https://www.newscientist.com/article/2226783-heat-can-quantum-leap-across-a-totally-empty-vacuum/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Quantum leap in computing as scientists claim ‘supremacy’
Scientists claimed Wednesday to have achieved a near-mythical state of computing in which a new generation of machine vastly outperforms the world’s fastest super-computer, known as “quantum supremacy”. …

Quantum Leap From Australian Research Promises Super-Fast Computing Power
An anonymous reader quotes a report from The Guardian: Simmons, a former Australian of the Year, and her team at the University of New South Wales announced in a paper published in Nature journal on Thursday that they have been able to achieve the first two-qubit gate between atom qubits in silicon, allowing them to communicate with each other at a…
