IBM tests quantum error-correction on AMD chips, marking key breakthrough

Quantum computers use qubits to solve problems beyond traditional computers, but errors are common; IBM’s new algorithm corrects these errors and now runs in real time on AMD’s field-programmable gate arrays

IBM announced on Friday (October 24) that it has successfully run a key quantum computing error-correction algorithm on commonly available chips from Advanced Micro Devices (AMD), marking a significant step toward commercializing quantum computers. The development comes as IBM competes with Microsoft and Google, which recently unveiled a breakthrough quantum algorithm.

Advancing quantum computing reliability

Quantum computers operate using qubits, which can solve complex problems that would take traditional computers thousands of years, such as simulating the behavior of trillions of atoms. However, qubits are highly error-prone, which can compromise computations. In June, IBM introduced an algorithm designed to correct such errors alongside quantum chips. A research paper, expected to be published Monday, reveals that IBM’s algorithm can now run in real time on AMD’s field-programmable gate arrays (FPGAs).

Jay Gambetta, IBM’s director of research, highlighted that the algorithm is not only effective in practical scenarios but also operates on affordable, widely available AMD chips. “Implementing it, and showing that the implementation is actually 10 times faster than what is needed, is a big deal,” Gambetta said.

Looking ahead

IBM aims to build a full-scale quantum computer, named Starling, by 2029, with the algorithm work already completed a year ahead of schedule. The announcement had a positive impact on the stock market, with IBM shares rising 7.88% to $397.46 and AMD shares increasing 7.63% to $252.92. This milestone underscores IBM’s progress in making quantum computing more reliable, scalable, and accessible using mainstream hardware.
