- IBM introduced two new quantum chips in latest step forward
- The Nighthawk chip increases circuit complexity by 30% over its predecessor
- Loon is IBM’s first chip to demonstrate full fault-tolerant components
IBM has announced two new quantum chips as part of its wider roadmap to achieve both quantum advantage and fault-tolerant computing by the end of the decade.
The company says the new Nighthawk and Loon chips mark a major leap toward making practical quantum computing a reality.
The new hardware, launched alongside advances in fabrication and software, aims to bridge the gap between experimental prototypes and commercially useful quantum systems.
Building the foundation for quantum advantage
The Nighthawk chip is designed to reach what IBM calls “quantum advantage,” the point at which a quantum computer can outperform all classical computing methods.
With 120 qubits and 218 tunable couplers arranged in a square lattice, the chip supports circuits with 30% greater…
