In December 2024, a team at Google published a result in Nature that physicists had been chasing for nearly three decades: a ...

Quantum computing promises to disrupt entire industries because it leverages the rules of quantum physics to perform calculations in fundamentally new ways. Unlike traditional computers that process ...

Over the past decade, quantum computing has grown into a billion-dollar industry. Everyone seems to be investing in it, from tech giants, such as IBM and Google, to the US military. But Ignacio Cirac ...

Interference helps keep quantum bits (qubits) stable by reducing outside disruptions. It speeds up calculations by letting ...

Quantum computing is starting to move out of the lab and into the real world—and the shift is happening faster than many expected. What was once viewed as a distant, theoretical technology is now ...

D-Wave Quantum Inc., a commercial supplier of quantum computing hardware and software, today announced an agreement to acquire the leading developer of gate-model quantum computing systems Quantum ...

Quantum computers promise to revolutionize our ability to solve problems thanks to their unique properties. However, a team of researchers has just discovered a computable task that appears impossible ...

The Defense Advanced Research Projects Agency is looking for companies to build the hardware and software quantum computers need to communicate and work together. Most quantum computers are standalone ...

After 30 months of fast-paced innovation in quantum algorithms, six research groups are hoping to hit paydirt. But there can be only one big winner—if there is a winner at all. I’m standing in front ...

It remains an open question when a commercial quantum computer will emerge that can outperform classical (non-quantum) machines in speed and energy efficiency while solving real-world combinatorial ...

Quantum computers are already here, but they make far too many errors. This is arguably the biggest obstacle to the technology really becoming useful, but recent breakthroughs suggest a solution may ...
