Quantum computers may slam into hard architectural walls long before they can crack the encryption protecting online banking, ...

D-Wave's Quantum Circuits acquisition and gate-model advances put QBTS ahead in speed, error correction and scalability for 2026.

A Google-led research team has demonstrated a surface-code logical qubit operating below the error-correction threshold, showing that logical errors can fall rapidly as the code scales up. The ...

In September, Microsoft made an unusual combination of announcements. It demonstrated progress with quantum error correction, something that will be needed for the ...

If you’ve ever sent a text message, played a CD, or stored a file in the cloud, you’ve benefited from error correction. This revolutionary idea dates back to the ...

Error-corrected magic: Clifford circuits attain universality – that is, the ability to compute any function that quantum theory permits – upon injection of special states called magic states.

Researchers from Google have demonstrated a new generation of quantum computer, called Willow, which is able to run its random circuit sampling (RCS) benchmark significantly faster than a ...
