About
Iceberg Quantum is a University of Sydney spinout developing hardware-agnostic quantum error correction architectures. The company raised a $2M pre-seed in March 2025 and a $6M seed round led by LocalGlobe with Blackbird and DCVC in early 2026, $8M in total. Its flagship Pinnacle architecture claims RSA-2048 could be broken with fewer than 100,000 physical qubits, dramatically below the millions estimated in conventional approaches, using quantum LDPC error correcting codes. Iceberg partners with PsiQuantum, Diraq, and IonQ to develop and validate its architecture. Based in Sydney, Australia.
