ParityQC is an Innsbruck-based quantum architecture company. In April 2026 it ran a 52-qubit Quantum Fourier Transform on IBM's Heron r3 processor, nearly doubling the previous 27-qubit record, enabled by its proprietary Parity Twine architecture that eliminates SWAP gates. The QFT underpins quantum algorithms in cryptography, finance and materials science — and the architecture is commercially licensable.
