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 ...

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 ...

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 ...

Chicago has quickly emerged as a hub for quantum computing, with the state of Illinois and technology companies pouring millions of dollars into developing a campus to build the world’s first ...
