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 quantum layer will will not be exhausted by one hardware modality, one algorithmic framework or one vendor’s roadmap.

Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough ...

A University of Sydney quantum physicist has developed a new approach to quantum error correction that could significantly ...

One paper finds that attacking the bitcoin blockchain through quantum mining would demand the energy output of a star.

New research suggests quantum computers capable of breaking internet encryption may arrive sooner than expected—with AI ...

Quantum computers struggle with a major flaw: their information vanishes unpredictably. Scientists have now created a new method that can measure this loss over 100 times faster than before. By ...

Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, ...

Explore the best college majors for quantum computing roles, the skills employers want, and how to choose the right program.

Two research groups say they have significantly reduced the amount of qubits and time required to crack common online ...

When the commercial, scalable, fault-tolerant quantum computing era really begins, when it becomes widely available, it will – least at the start – be a cloud service that is integrated with classical ...
