Israeli startup Qarakal Quantum has introduced the "Pangaea" architecture, a 3D superconducting design that reduces physical qubit overhead by an order of magnitude compared to standard planar layouts. By utilizing an auxiliary gauge-code strip as a quantum bus, this approach mitigates routing bottlenecks and lowers wiring density while supporting heterogeneous topological codes for fault-tolerant operations at scale. This marks a significant architectural shift toward modular, backplane-connected systems that address critical scaling challenges in superconducting quantum computing.

Qarakal Quantum Unveils “Pangaea” Modular Architecture to Cut Qubit Overhead by 10X

Quantum Computing ReportAugust 5, 20262 min read

Israeli quantum startup Qarakal Quantum Ltd. has officially launched Pangaea, a modular, three-dimensional superconducting quantum computing architecture engineered to reduce the physical qubit requirements of fault-tolerant systems by an order of magnitude. Published in an arXiv pre-print titled "The Pangaea Architecture: Fault-Tolerant Heterogeneous Topological Codes via a Quantum Bus," the design resolves the long-standing routing [...] The post Qarakal Quantum Unveils “Pangaea” Modular Architecture to Cut Qubit Overhead by 10X appeared first on Quantum Computing Report.
