Mathematicians have found a way to transform an unproductive quantum computing approach by reviving a class of previously discarded particles. Quantum computers can solve problems beyond the capabilities of classical computers by using principles like superposition. This means a quantum bit, or qubit, can represent both 0 and 1 simultaneously, similar to the famous thought experiment of a cat being …

In a new roundup of promising advances in quantum physics, researchers are revealing the upcoming cutting-edge studies they hope will finally lead to reconciling the quantum framework with the pesky issue of its unclear relationship to gravity. Quantum physics may have weathered 100 years of scientific examination, with relevance to everything from the periodic table to the shine of stars …

A US military space-plane, the X-37B orbital test vehicle, is due to embark on its eighth flight into space on August 21 2025. Much of what the X-37B does in space is secret. But it serves partly as a platform for cutting-edge experiments. One of these experiments is a potential alternative to GPS that makes use of quantum science as …

Researchers from the Austrian Academy of Sciences and the University of Vienna have demonstrated a precise method for reversing time in a quantum system, achieving an average fidelity of more than 95%. The study, published in Optica, shows that it is possible to make a quantum particle return to a previous state without knowing anything about its internal dynamics—a feat …

Quantum computing is either a distant dream or an imminent reality depending on whom you ask. And while much of this year’s Quantum Village at the Defcon security conference in Las Vegas is focused on emerging research and threat analysis, Village cofounders Victoria Kumaran and Mark Carney are also working to make a currently available quantum technology more accessible to …

Famous American writer Isaac Asimov once said, “There is an art to science, and science in art.” A new study proves this quote right by highlighting a never-before-seen connection between Vincent van Gogh’s famous painting “The Starry Night” and quantum physics. The main focus of the study is the Kelvin–Helmholtz instability (KHI), an effect observed in the everyday world when …

Researchers at IBM and Moderna have successfully used a quantum simulation algorithm to predict the complex secondary protein structure of a 60-nucleotide-long mRNA sequence, the longest ever simulated on a quantum computer. Messenger ribonucleic acid (mRNA) is a molecule that carries genetic information from DNA to ribosomes. It directs protein synthesis in cells and is used to create effective vaccines …

States in quantum superposition are notoriously fragile, but researchers in China have reported creating such a state that lasted for a whopping 23 minutes and 20 seconds. While this record-breaking result is exciting in itself, the team believes that it could open new ways to high-precision measurements and even information processing for quantum computers – possibly even allowing scientists to …
