IBM Reveals Plan to Build World's First Fault-Tolerant Quantum Computer by 2029
Jun 10, 2025
IBM has announced a detailed plan to build the world's first large-scale, fault-tolerant quantum computer—named Quantum Starling—by 2029. The company unveiled its roadmap on Tuesday, sharing steps and new hardware that will pave the way for this advanced system.
The Quantum Starling computer aims to solve one of the main challenges in quantum computing: errors. Unlike today's quantum computers, which can be sensitive and make mistakes, a fault-tolerant machine can run complex tasks much more reliably. IBM's new plan includes the development of processors like Loon, Kookaburra, Cockatoo, and the upcoming Nighthawk, all leading up to the final Starling system.
According to IBM, the Starling quantum computer is projected to handle 20,000 times more operations than current quantum machines. The computational power will be so great that representing just the computer's state would require more memory than a massive number of today’s most powerful supercomputers combined.
Investors reacted positively to IBM's announcement, with the company's stock reaching a new all-time high following the news.
