ParityQC demonstrates a 52-qubit Quantum Fourier Transform on IBM Heron architecture
ParityQC demonstrated a 52-qubit Quantum Fourier Transform (QFT) implementation on IBM's Heron-architecture quantum processor. The QFT is a foundational primitive for Shor's algorithm and quantum phase estimation; the 52-qubit instance is among the larger published QFT executions on superconducting hardware.
Named-metric benchmark (QFT qubit count on a specific named hardware) meets §7.3(b) and the score-6 anchor for credible benchmark results with industry-wide implications. Below score 7 because QFT scale improvements are expected as qubit counts grow; first-of-kind would push higher.
Puts pressure on ion-trap and neutral-atom systems to publish comparable QFT scales; informs the feasibility discussion ahead of near-term Shor-resource-estimate work (cf. 2026-03-31 Caltech/Oratomic paper).
