In contrast to classical computers, which operate on bits that can only take the basic values 0 and 1, quantum computers operate on "qubits," which can assume any superposition of the computational ...

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

These novel error-correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, with applications in diverse fields ...

There’s a strong consensus that tackling most useful problems with a quantum computer will require that the computer be capable of error correction. There is ...

Quantinuum has unveiled a third-generation quantum computer that could be easier to scale up than rival approaches. The US- and UK-based company Quantinuum today unveiled Helios, its third-generation ...
