ONE snowy day last year, I trekked out of Vienna, Austria, winding my way to one of the city’s graveyards to visit the final resting place of a giant of 19th-century physics. Ludwig Boltzmann’s tombstone features an imposing bust of the man, frowning down with a severe expression. And there …

Researchers created a tornado-like vortex in superfluid helium Kichigin/Shutterstock A giant quantum vortex may allow researchers to study black holes. This vortex is an eddy in a special form of liquid helium that displays quantum effects. The result has some properties similar to black holes, allowing it to act as …

Eventually, a network of quantum computers could enable the creation of a more secure quantum internet hh5800/Getty Images To shop on the unhackable quantum internet, we will need new security techniques. Though we do not have a fully operational quantum internet yet, researchers have now demonstrated a proof of concept …

We probably don’t need to worry about quantum computers being able to break encryption in 2024, but cryptographers are planning a security upgrade just in case Source link

Around 200 molecules were turned into a quantum state of matter Will Lab, Columbia University A quantum state of matter has been made for the first time using “dipolar” molecules – molecules that have a positively charged end and a negatively charged end. It could help enhance our understanding of …

You can’t cheat at quantum marbles PRE In quantum mechanics, it is impossible to know both exactly where you are and exactly where you are going. This idea, known as Heisenberg’s uncertainty principle, has been a key part of studying the quantum realm for almost a decade – but now …

The double-slit experiment shows how light can act as a wave Timm Weitkamp/Wikimedia, CC by 3.0 The classic double-slit experiment of quantum physics involves shining light through two narrow gaps to show that it can behave as a wave – now it seems the slits can be entirely replaced by …

Quantum computers could become more useful now researchers at Google have designed an algorithm that can translate complex physical problems into the language of quantum physics Source link

In the foothills to the south of Rome sits Italy’s premier nuclear physics lab, the National Laboratory of Frascati. It has all the equipment you would expect at a cutting-edge science facility, with huge magnets, powerful particle accelerators and exposed electric cables spilling out everywhere. Many of the researchers here …

QuEra’s new quantum computer is a step towards practically useful devices QuEra Another quantum computing record has been broken. A team has built a quantum computer with the largest ever number of so-called logical qubits, or quantum bits. Unlike standard qubits, logical qubits are better able to carry out computations …
