American researchers from Duke University have created a protocol for tracking errors in a quantum computer at each stage of its operation. As a result, the scientists managed to create a quantum computer that almost does not make mistakes.
A new method of error correction for a quantum computer has allowed scientists from the United States to assemble an extremely noise- and error-resistant next-generation quantum computing system. The error-correction protocol allows errors to be tracked at each step of the computer’s operation, resulting in a total error rate of less than 1%.
The scientists conducted an experiment in which they combined several qubits into one, and used an innovative method of error correction, which allowed them to minimize the noise of the quantum system, which disturbs the reliability of calculations. The result of the scientists’ work was a system capable of efficient error-tracking in automatic mode.
Resistant to errors logical qubit quantum computer – an important achievement for science, which brings an era of quantum computing. The authors of the new scientific work are confident that their technology will find the widest application in new quantum computing devices, which will contribute to the popularization of such computing.
