Technology giant IBM has reached a major milestone in its quantum ambitions and has unveiled a new chip and machine that it hopes can help solve problems beyond the scope of traditional computers. The ...

Add Yahoo as a preferred source to see more of our stories on Google. Just like any machine, quantum computers are prone to make errors. These errors can cause the qubits to lose their quantum states, ...

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

Someday, somebody, somewhere will likely have a quantum computer capable of cracking the fragile codes that underpin every piece of data we exchange over the internet. We don’t know when. It could be ...

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 ...

"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 ...

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 ...
