[Verse 1] Classical keys were safe and sound RSA and DES held their ground But quantum bits are spinning free Superposition's the master key While classical computers crawl through each door Quantum machines explore them all and more [Chorus] Shor's algorithm breaks the code Grover's search will find the road Qubits dance in parallel states Every cipher meets its fate Quantum threat is coming near Classical crypto disappears [Verse 2] Factorization used to take Billions of years for hackers' sake But Shor can crack the numbers wide In polynomial time with quantum pride Public keys that seemed so strong Won't protect us very long [Chorus] Shor's algorithm breaks the code Grover's search will find the road Qubits dance in parallel states Every cipher meets its fate Quantum threat is coming near Classical crypto disappears [Bridge] Entanglement and interference Make quantum computing fierce Hash functions lose their power Cut their strength by half each hour Symmetric keys need doubling size To survive quantum's prying eyes [Verse 3] AES and hashes stand their ground But need more bits to stay secure and sound Elliptic curves will crumble fast Their mathematical strength won't last We need new crypto quantum-safe To keep our secrets in their place [Chorus] Shor's algorithm breaks the code Grover's search will find the road Qubits dance in parallel states Every cipher meets its fate Quantum threat is coming near Classical crypto disappears [Outro] The race is on to find new ways Before the quantum judgment day Post-quantum crypto leads the fight To keep our data safe from sight
