"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they ...

Two-dimensional projection of a quantum spherical code composed of two copies (black and red) of the four complex dimensional Witting polytope. This code can correct up to five photon losses of any ...

A multinational team has cracked a long-standing barrier to reliable quantum computing by inventing an algorithm that lets ordinary computers faithfully mimic a fault-tolerant quantum circuit built on ...

THE AGE of quantum computing is coming closer, presenting both an opportunity and a risk for individuals, companies and governments. Host Alok Jha explores why quantum computers threaten to crack the ...

Quantum computing firm D-Wave says its devices can solve problems that would be virtually impossible for classical computers – but two separate research groups have now cast doubt on the claim. That ...
