BERNE — Quantum teleportation under silent siege. Coherence decay and cryptanalysis in mortal duel. The channel holds—for now. But memory decay tightens the noose. Every millisecond a lifeline, every kilometer a risk. Secure distance shrinks to 191 km.
BERNE, 20 APRIL — Quantum Relay 7 cold, its fiber lines humming with encoded desperation. The air reeks of ionized silica and failing coherence. We have confirmation: the classical correction channel is armored with post-quantum cryptography, yet the quantum memory’s 1 ms lifespan strangles the corridor. Secure teleportation now capped at 191 km—FrodoKEM’s weight too great, Kyber512’s edge fleeting. The adversary’s chance rises, then falls: a bell-shaped window of vulnerability, peaking where decryption lag meets decoherence. Beyond 199 km, the signal dissolves into noise. But here’s the warning: leakage of correction bits—whether in bursts or steady seep—erodes fidelity faster than amplitude damping alone. Holevo bounds tighten. If we do not harden the memory interface, the channel will fall not with a breach, but a whisper.
