"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 ...
