Iceberg Quantum and Diraq Demonstrate Pinnacle qLDPC Architecture on Spin Qubits

Insider Brief

• Iceberg Quantum and Diraq have demonstrated an implementation of Iceberg’s Pinnacle qLDPC architecture on Diraq’s spin-qubit hardware using NVIDIA CUDA-Q Logical.
• The companies report that Pinnacle can target 1,000 logical qubits with 150,000 physical qubits on Diraq’s platform while maintaining its projected logical performance advantage.
• The work includes hardware mapping, shuttling-aware noise simulations and end-to-end compilation of logical primitives using CUDA-Q Logical.

PRESS RELEASE — Today we’re announcing work done by Iceberg Quantum and Diraq, leveraging early access to the newly announced Logical layer of the NVIDIA CUDA-Q platform. The work demonstrated how Iceberg Quantum’s Pinnacle architecture can be implemented on Diraq’s spin-qubit hardware platform while preserving Pinnacle’s logical performance advantage.

It is often assumed that quantum low-density parity-check (qLDPC) architectures such as Pinnacle require significantly more complex quantum hardware than surface code. This work shows that need not be the case. Pinnacle can be implemented on Diraq‘s hardware without demanding significantly more of the platform than a standard surface code approach.
