Quantum Startup Qarakal Takes Lessons From Classical Systems With Pangaea Architecture Advancements in quantum computing continue to pile up in areas from error correction and infrastructure to software and algorithms, sharpening the view of what the once-theoretical compute paradigm will look like when it reaches its full fault-tolerant, useful, and practical potential. Architecture will play a central role in all of this, and as we have seen in past months, the focus on this aspect of quantum computing is accelerating. Recently, that’s included the work that D-Wave scientists – they of the annealing quantum systems – are doing with the vendor’s dual-rail superconducting architecture, as well as QuiX Quantum’s introduction of the Dedalo architecture for its fault-tolerant photonics-based systems, taking a significant step forward with its Carina commercial system. The effort being put into developing the architecture around quantum computing shouldn’t be a surprise, says Nadav Katz, co-founder and chief technology officer for Qarakal Quantum, a startup founded in 2024 in Israel. The architecture work signals a growing maturity in the quantum space, “a realization that quantum computers are computers, not a pile of qubits that you make and then hope that by some sort of magic programming, it will converge to a full computational system,” Katz tells The Next Platform. Architecture will be key in shifting quantum computing from institutional and vendor labs and cloud environments into the commercial space, creating modular, scalable, and efficient systems that can fit in datacenters alongside classical enterprise and supercomputers. Focusing on architecture and hardware also touches on a deeper question of how information is handled and how the industry will need to think about how to program a real quantum system. “The current boogeyman of quantum computing is this sort of monolithic architecture in which you just say, 'Let's just have this
