[Verse 1] In quantum realms where fragile states reside Thermal phonons shake the crystalline spine While charge fluctuations ripple through the grid Magnetic fields drift, breaking the design Each qubit trembles on its razor's edge Where perfection crumbles by the microsecond [Chorus] Noise corrupts, decoherence steals Every quantum dream that once felt real Bit flips, phase kicks, T1 and T2 Error syndromes paint the qubits blue But codes can catch what chaos throws Surface codes and Shor's transpose [Verse 2] Relaxation drains the energy away While dephasing scrambles superposition's grace Crosstalk whispers between neighboring gates Leakage bleeds beyond the computational space Control pulse jitter spoils the rotation Gate infidelity compounds through operations [Chorus] Noise corrupts, decoherence steals Every quantum dream that once felt real Bit flips, phase kicks, T1 and T2 Error syndromes paint the qubits blue But codes can catch what chaos throws Surface codes and Shor's transpose [Bridge] Syndrome extraction reads the parity checks While ancilla qubits guard the logical text Threshold theorems promise scaling heights If physical error rates stay beneath the knife Dynamical decoupling spins away the bath Echo sequences cancel the unwanted path [Verse 3] Stabilizer codes span the Hilbert space With generators checking each encoded place Repetition guards against the single flips While Steane codes handle both bit and phase slips Active correction feeds back to the source Passive protection shields with symmetric force [Chorus] Noise corrupts, decoherence steals Every quantum dream that once felt real Bit flips, phase kicks, T1 and T2 Error syndromes paint the qubits blue But codes can catch what chaos throws Surface codes and Shor's transpose [Outro] In this noisy intermediate-scale quantum age We build resilience page by careful page Though perfection eludes our current reach Error mitigation extends what we can teach
