Researchers Run Textbook Quantum Cryptanalysis on Real IBM Hardware
Using Simon's algorithm on an IBM Heron-generation machine, the team recovered hidden periods in an Even-Mansour cipher structure, scaling from N=4 to N=10.
A new arXiv preprint reports what the authors describe as genuine, uncompiled, textbook-faithful quantum cryptanalysis executed on real IBM quantum hardware, an ibmkingston machine of the Heron generation. Using Simon's algorithm, which fin…

Quantum Hardware Closes on Cryptanalysis
As quantum machines steadily enlarge the problems they can solve on real hardware, demonstrations of cryptanalytic primitives keep advancing, pushing post-quantum migration from precaution toward necessity.
