Specifically, it is a method with a complex name—high-rate concatenated quantum codes—and what is innovative is that the logical qubits can be visualized mathematically as forming what is known as a ...

Quantum error correction codes enable efficient scaling to hundreds of thousands of qubits
"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 ...
Code-based cryptography is a promising branch of post-quantum cryptography that exploits the inherent complexity of decoding linear error-correcting codes. Traditional schemes, such as the McEliece ...
On that front, Hyperstone developed its own error-correction engine—a hard- and soft-decision error-correction module based on generalized concatenated codes.
The same codes needed to thwart errors in quantum computers may also give the fabric of space-time its intrinsic robustness. Unlike binary bits of information in ordinary computers, “qubits” consist ...
