[Verse 1] In quantum labs where qubits gleam Raw count alone won't tell the scheme A hundred noisy gates that fail Beat perfect two without betrayal The question haunts each quantum dream How do we measure what's supreme? [Chorus] Quantum Volume tells the tale Count times fidelity without fail QV equals width times depth When coherence hasn't left Square the qubits, test the noise This metric speaks with clearest voice [Verse 2] IBM devised this golden rule A comprehensive benchmarking tool Random circuits probe the core Square matrices explore Each gate's precision multiplied By qubit armies side by side [Chorus] Quantum Volume tells the tale Count times fidelity without fail QV equals width times depth When coherence hasn't left Square the qubits, test the noise This metric speaks with clearest voice [Bridge] Sixty-four beats thirty-two When gates perform what they should do A thousand qubits mean nothing If decoherence clips their wing The volume grows exponentially When both dimensions bloom potentially [Verse 3] Heavy hex patterns dance and weave Testing what machines achieve Success rates must exceed the line Where classical algorithms shine Two thirds correct becomes the floor Quantum advantage starts to soar [Final Chorus] Quantum Volume tells the tale Count times fidelity without fail Width and depth in harmony Measuring true quantum mastery When the threat assessment calls QV shows which system conquers all [Outro] Not just qubits, not just speed Volume measures quantum deed
