Quantum computers have become the latest canvas for humanity’s oldest fantasy: escaping death. Startups, futurists, and speculative essays now suggest that machines built to manipulate qubits could ...

Quantum circuits are supposed to gain power as they grow longer, but noise changes the picture. A new study finds that earlier steps in these circuits gradually lose their impact, with only the final ...

What if the most complex problems plaguing industries today—curing diseases, optimizing global supply chains, or even securing digital communication—could be solved in a fraction of the time it takes ...

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 entanglement occurs when two subatomic particles become linked in such a way that their properties remain connected, no matter how far apart they are. A change to one particle seems to ...

After decades spent gestating in labs, quantum computing has finally reached an inflection point between theoretical promise and practical implementation. From discoveries in pharmaceutical and ...

The promise of quantum computers appears to be that they will upend modern computing as we know it. With exceptional computational power, they’ll be performing feats unimaginable for any classical ...

Dr. Dominic Williamson, a University of Sydney quantum physicist, has developed a new approach to quantum error correction that could significantly reduce the number of physical qubits required to ...

So, what exactly is the quantum chemistry definition? It sounds fancy, right? Basically, it’s about using the weird rules of quantum mechanics to figure out how molecules work. Think of it as the ...

Wave, the testnet has drawn 13,000 sign-ups and early work from six research teams, but remains an experimental environment ...

John Martinis is a hardware guy. He prefers the nitty-gritty of doing physics in the lab over the idealised world of textbooks. But you couldn’t write the quantum computing history books without him: ...
