A quantum version of RAM might improve long-distance quantum networks Dmitriy Rybin/Shutterstock A quantum version of a random access memory can read and write information 1000 times, and could eventually become a key component in long-distance quantum networks. In conventional computers, random access memory (RAM) is essential for short-term information …

A D-Wave Advantage quantum computer in Julich, Germany Lukas Schulze/Getty Images Quantum computers can now solve problems with real-world applications faster than any ordinary computer, suggesting they could be commercially viable, say researchers at quantum computing firm D-Wave – though outside observers are more cautious. It had long been hoped …

Can quantum computers be useful? Eric Lukero/Google Google and XPRIZE are launching a $5 million competition to find practical uses for quantum computers that could actually benefit society. We already know that quantum computers can perform specific tasks faster than classical computers, after Google first claimed quantum advantage for its …

All objects exert a gravitational pull, no matter how small Karl Dolenc/BeholdingEye/Getty Images A device that can measure the gravitational force on a particle that weighs less than a grain of pollen could help us understand how gravity works in the quantum world. Despite keeping you stuck to the ground, …

There is a brand new way to keep things cool Botyev Volodymyr/Shutterstock A new type of cooling relies on an exotic quantum mechanical property rather than putting objects into cold environments like refrigerators – and it might one day help us chill things to temperatures lower than any we have …

An optical cavity like this could be used in a quantum engine Max Planck Institute of Quantum Optics A single atom inside of a reflective cavity could be enough to drive a piston in a tiny, quantum version of an engine. The essential feature of any engine is that it …

IBM is one of many companies working on quantum computers Nearly a fifth of all difficult-to-correct errors in quantum computers are caused by powerful particles from space hitting the machines. While these cosmic ray-induced errors have long been predicted by scientists, this first precise measurement of how often they occur …

A phenomenon called the Fermi resonance, which affects how molecules vibrate, is responsible for a large part of carbon dioxide’s planet-warming effect Source link

A quantum experiment that could separate a particle’s properties from its mass has physicists arguing over how reality works in the quantum world Source link

Could quantum computers be made more stable using time crystals? John D/Getty Images Time crystals can be used to stabilise fragile states within quantum computers, which could one day give them an edge over traditional computers. When Nobel laureate Frank Wilczek first theorised that time crystals exist in 2012, the …
