Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can be ...
Just like any machine, quantum computers are prone to make errors. These errors can cause the qubits to lose their quantum states, leading to inaccurate computations. To address this problem, quantum ...

China’s quantum computer harnesses microwaves to challenge Google’s supremacy
Researchers at USTC in China turned to microwave-based error correction to achieve a distance-7 logical qubit, much like ...
"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 ...
The quantum low-density parity check (QLDPC) codes, the “holy grail” of quantum error correction research and development for 30 years, have a breakthrough ...
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 ...
Computer scientists say they’ve cracked the science behind error-correction in quantum computers thanks to new "4D codes." Developed by Microsoft, the new codes were revealed in a blog post published ...
Quantum error correction (QEC) and fault-tolerant computation provide the critical framework for realising reliable quantum processors in the presence of inevitable ...
For the first time, a quantum computer has improved its results by repeatedly fixing its own mistakes midcalculation with a technique called quantum error correction ...
