[Verse 1] In quantum realms where qubits dance and sway Decoherence creeps in every single day One photon lost, one phase flip goes astray Our computation fades and slips away But we've got codes to guard what matters most Surface codes spread across a lattice host [Chorus] Error correction, quantum protection Syndrome detection saves the day Logical qubits, physical qubits Surface codes show us the way Magic state distillation Fault tolerance is our salvation When noise attacks, we bounce right back Quantum computing's here to stay [Verse 2] Picture a grid of qubits in a square Data qubits hold the info that we care Ancilla qubits measure parity Syndromes tell us where errors dare to be X and Z stabilizers standing guard Making quantum computation less hard [Chorus] Error correction, quantum protection Syndrome detection saves the day Logical qubits, physical qubits Surface codes show us the way Magic state distillation Fault tolerance is our salvation When noise attacks, we bounce right back Quantum computing's here to stay [Bridge] Threshold theorem gives us hope Below the limit we can cope One percent error rate or less Surface codes handle all the mess T gates are tricky, that's the thing Magic states are what they bring Distill and purify with care High fidelity gates we'll share [Verse 3] Clifford gates come easy, they're so clean But T gates make the universal scene Magic state distillation is the key Turning noisy states to purity Fifteen to one or even more we need But fault tolerance plants the quantum seed [Chorus] Error correction, quantum protection Syndrome detection saves the day Logical qubits, physical qubits Surface codes show us the way Magic state distillation Fault tolerance is our salvation When noise attacks, we bounce right back Quantum computing's here to stay [Outro] From surface codes to magic state design The quantum future's looking mighty fine Error correction paves the yellow brick road To algorithms that will crack any code
