Quantum hardware has finally crossed a psychological threshold: it is no longer a science project in search of a purpose, it is a working tool that large companies and governments are starting to use.

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 ...

The world’s only vertical quantum center, DQC was founded by leading quantum scientists in 2021. Led by Kenneth Brown, DQC ...

Quantum computing marks a major change in how we process information. It goes beyond the binary limits of classical "bits," which exist only as 0 or 1. Instead, it uses "qubits" that can exist in ...

Quantum computing promises a new generation of computers capable of solving problems hundreds of millions of times more quickly than today’s fastest supercomputers. This is done by harnessing spooky ...

I see three investment lanes for quantum computing: pure plays like IonQ (IONQ) and Rigetti (RGTI); the "Magnificent Seven" giants with quantum divisions; and infrastructure picks-and-shovels. Which ...

Quantum computing has long felt like a perpetual promise — a mysteriously powerful technology that’s always “about 10 years away.” If you tuned it out, you weren’t alone. But something has shifted ...
