Selective orthogonality preserves classical LDPC design freedom. The resulting [ [9216,4612,d]] code (d≤48) protects 4,612 logical qubits with 9,216 physical qubits, has girth 8, provides strong ...

The LDPC code breakthrough, why small random parity sets outsmarted every structured approach
When transmitting data across noisy channels, the quest for perfect reliability seemed to demand ever-more complex structure — until Robert Gallager's 1960 insight showed that small, randomly assigned ...
In the world of quantum error correction, an underdog is coming for the king. Last week, new simulations from two groups reported that a rising class of quantum error ...
A new technique for efficient encoding of LDPC codes based on the known concept of Approximate Lower Triangulation (ALT) is introduced. The greedy permutation algorithm is presented to transform ...
