Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough ...

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies ...

Quantum computers struggle with a major flaw: their information vanishes unpredictably. Scientists have now created a new method that can measure this loss over 100 times faster than before. By ...

However, it is not necessary to use fancy quantum cryptography technology such as entanglement to avoid the looming quantum ...

“In quantum computers, information is transmitted and stored using so-called qubits (quantum bits). But quantum information ...

Charles H. Bennett and Gilles Brassard, winners of this year’s Turing Award, spent their lives touting the advantages of the ...

International Business Machines (NYSE: IBM) has been working on quantum computing technology for decades. The company's quantum computing roadmap calls for a demonstration of quantum advantage, where ...

For decades, quantum computing has been heralded as a technology of the future, promising to solve problems far beyond the reach of supercomputers. But its practical use has remained elusive. That’s ...

Australia’s quantum push is accelerating, with real systems, bold timelines, and breakthroughs like quantum twins signaling a ...

One paper finds that attacking the bitcoin blockchain through quantum mining would demand the energy output of a star.
