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 …

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 …

The team’s graphene device, grown on a silicon carbide substrate chip Georgia Institute of Technology A working, scalable semiconductor has been created from graphene for the first time, potentially paving the way for a new type of computer with greater speed and efficiency than today’s silicon chips. But despite graphene’s …

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

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

Passive cooling could be more efficient using a device containing a salt water solution daniiD/Shutterstock Computers could see their performance jump by one-third through an inexpensive cooling solution based on lithium bromide salt – all while enjoying 10 times longer cooling than using alternative passive cooling systems. To remove heat …

MosaiQ’s generated images (bottom row) on a quantum computer look similar to items in the initial data (top row) and seem better than those made by other quantum methods (other rows) Daniel Silver et al. 2023 Artificial intelligence running on a quantum computer can now generate recognisable images of things …

An illustration of a quantum computer Pete Hansen/Shutterstock Quantum computers could run more quickly if they contained tiny quantum refrigerators. Quantum computers process information using quantum bits, or qubits, which must be reset to a special state between running programs. Teruaki Yoshioka at the Tokyo University of Science says slow …

Heat instead of electricity could power more efficient computers Yurchanka Siarhei/Shutterstock A computer that uses heat instead of electricity could run algorithms that power neural networks and artificial intelligence – and tamp down their energy budgets. “We have things like ChatGPT which can learn very complicated things about language, but …
