To overcome this problem, high-rate quantum codes, such as quantum low-density parity-check codes, have been considered. With this approach, the logical gates, which make calculations possible, have ...

"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 ...

Various methods are used to correct errors in quantum computers. Not all operations can be implemented equally well with different correction codes. Therefore, a research team has developed a method ...

IQM Quantum Computers has developed a new quantum error-correcting code that it says can reduce logical error rates by up to 1,000 times compared with the widely used ...

These novel error-correction codes can handle quantum codes with hundreds of thousands of qubits, potentially enabling large-scale fault-tolerant quantum computing, with applications in diverse fields ...
