Superconducting qubits—bits of quantum information—have been widely considered a promising technology for moving quantum ...

Quantum Art's new QPU could be both significantly smaller and also faster than competing quantum architectures. How can we reinvent quantum computing? Perhaps by shrinking it down and making it small: ...

Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough machine may be built much sooner than previously thought ...

A device smaller than a grain of dust is emerging as a surprisingly powerful candidate to reshape how quantum computers are built and scaled. Instead of relying on room-filling optics and fragile lab ...

In the pursuit of powerful and stable quantum computers, researchers at Chalmers University of Technology, Sweden, have developed the theory for an entirely new quantum system – based on the novel ...

Pushing against years of scepticism, an analysis suggests quantum computers may offer real advantages for running machine ...

Quantum hardware and software are advancing rapidly – and our online encryption systems need to change to stay ahead.

As US defence research agency DARPA starts a programme to upend the dominant quantum computing architecture it says will fail ...

For decades, quantum computing has been heralded as a technology of the future, promising to solve problems far beyond the reach of supercomputers. But its practical use has remained elusive. That’s ...

A major obstacle in the development of powerful quantum computers is the growing number of cables required to control a ...

Although the potential applications of quantum computing are widespread, a new feasibility study suggests quantum computers still face major hurdles in solving quantum chemistry problems. The study, ...
