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 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 ...

We may receive a commission on purchases made from links. You've probably heard the term "quantum computing" at some point and wondered what it meant. It's not a term that's easy to understand, and ...

Quantum vendors and national agencies are aligning to establish common standards for logical qubits, which should enable ...

So, what exactly is quantum theory in physics? It sounds super complicated, right? Like something only geniuses ...

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 ...

Quantum computers of the future may be closer to reality thanks to new research from Caltech and Oratomic, a Caltech-linked start-up company. Theorists and experimentalists teamed up to develop a new ...

Work has begun on the state’s new multibillion-dollar quantum computing campus on Chicago’s South Side. The lakefront site for the Illinois Quantum and Microelectronics Park was for decades U.S. Steel ...
