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 ...

"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 ...

Scientists at the Institute of Science Tokyo have announced a breakthrough in quantum error correction that could bring a large-scale quantum computer closer to ...

Quera show 580 and 1156 logical qubits with neutral atom quantum computer simulations. April 2026 breakthrough (with Harvard/MIT) they shiow high-rate codes achieving over 50% encoding rate. They are ...

By using LDPC codes on a cat-qubit architecture, this latest work not only shows how the qubit footprint of a fault tolerant quantum computer could be further reduced but overcomes two key challenges ...

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 ...

Researchers have demonstrated that the theoretically optimal scaling for magic state distillation—a critical bottleneck in fault-tolerant quantum computing—is achievable for qubits, improving on the ...

The company’s forthcoming quantum processor, IBM Starling, was unveiled today, with officials saying it promises efficiency without burdensome overhead. IBM ...

Many experts predict that practical fault tolerant quantum computing (FTQC) will require millions of physical quantum bits (qubits) but in August, 2023 IBM scientists ...
