[Verse 1] In a world of quantum danger looming near Classical crypto starts to disappear But there's a fortress built on lattice ground Where vectors hide and can't be found Points arranged in patterns infinite Like crystal structures, benefits Each dot connected to the next in line A mathematical design divine [Chorus] Lattice holds the key, SVP's the mystery Shortest Vector Problem keeps us safe and free Learning With Errors, randomness that never tires Post-quantum armor that the future requires Grid of hope, grid of trust When quantum comes, it's lattice or bust [Verse 2] Picture dots on graph paper spread so wide In dimensions where our secrets hide The shortest path between two points of light Is harder than it seems to find just right Even quantum speedup hits a wall When lattice problems make computers crawl No algorithm yet can crack the code When vectors take the winding road [Chorus] Lattice holds the key, SVP's the mystery Shortest Vector Problem keeps us safe and free Learning With Errors, randomness that never tires Post-quantum armor that the future requires Grid of hope, grid of trust When quantum comes, it's lattice or bust [Bridge] LWE adds the noise we need Random errors help us succeed Hide the signal in the static Makes our crypto automatic Basis vectors span the space Quantum can't keep up the pace [Verse 3] While Shor's algorithm breaks RSA apart Lattice problems guard the cryptic heart NP-hard in worst case scenarios Even average case, the hardness grows From NTRU to the newer schemes Lattice builds our quantum dreams Ring signatures and homomorphic too All protected by this lattice view [Chorus] Lattice holds the key, SVP's the mystery Shortest Vector Problem keeps us safe and free Learning With Errors, randomness that never tires Post-quantum armor that the future requires Grid of hope, grid of trust When quantum comes, it's lattice or bust [Outro] When the quantum age arrives at last And classical methods are the past Remember how the lattice stood Protecting all we hold as good
