IBM has launched an experimental quantum computing chip named "Loon", marking a critical step toward its goal of building a practical quantum computer by 2029.
Quantum computers are expected to revolutionize computing, solving problems that are virtually impossible for classical systems. However, quantum instability causes high error rates, making error correction a central challenge. IBM, Google, and Amazon are all racing to develop viable solutions.
IBM’s approach is notably innovative. In 2021, the company proposed applying signal-processing algorithms—similar to those used in mobile communications—to quantum error correction. By combining quantum and classical chips, the system can identify and correct errors in real time.
Gartner VP Mark Horvath described the method as "very clever," though he noted the increased manufacturing complexity, as the chip must incorporate qubits while establishing new inter-qubit connections.
The Loon chip was developed at IBM’s Albany NanoTech Complex in New York, a facility with over 100,000 square feet of semiconductor manufacturing space and equipment on par with the world’s most advanced chip fabs.
While Loon remains in early testing, IBM also announced the Nighthawk quantum chip, set for release by the end of 2025. The company expects Nighthawk to outperform classical computers in specific tasks by late 2026. IBM is sharing related code with startups and researchers to accelerate industry validation.
