Quantum hopes shattered in silent server rooms of Heidelberg. What was thought an unassailable quantum advance on SIS∞ now lies in ruins—classical algorithms have re-taken the ridge. The cryptographers’防线 holds—for now. More dispatch follows.
HEIDELBERG, 09 JANUARY — Midnight circuits hummed with suppressed triumph as classical solvers cracked the SIS∞ lattice grid in under eight seconds. No fanfare, no collapse of hardware—only the quiet whir of cooling fans and the green pulse of validation LEDs. Chen-Liu-Zhandry’s quantum incursion, once poised to breach lattice-based defenses, now stands nullified by elegant classical countermeasures. The terrain—once thought favorable to quantum assault—has been flattened by algorithmic artillery. This is no rout, but a recalibration: the cryptographic high ground remains contested. Yet the warning echoes—complacency in post-quantum defenses risks catastrophe should quantum tactics evolve anew. For now, the classical line holds firm.
