[Verse 1]
In the lab they shine so bright, qubits dancing in the light
Single gates and perfect states, proof of concept looks so right
But the journey's just begun, from the few to millions run
Error rates start climbing high when we scale beyond the sky
[Chorus]
SCALE - Stability, Connectivity, Architecture, Logic, Error correction
FAULT - Fidelity, Algorithms, Understanding, Logic gates, Threshold crossing
From the lab to quantum advantage
We must bridge this scaling challenge
[Verse 2]
Two-qubit gates are hard to build when the neighbors aren't connected
Limited topology means some algorithms get rejected
Physical qubits break apart, logical qubits steal the heart
Encoding schemes protect the dream but overhead tears apart
[Chorus]
SCALE - Stability, Connectivity, Architecture, Logic, Error correction
FAULT - Fidelity, Algorithms, Understanding, Logic gates, Threshold crossing
From the lab to quantum advantage
We must bridge this scaling challenge
[Bridge]
Surface codes and magic states
Distillation compensates
When the error threshold's crossed
All the noise becomes our boss
But below that sacred line
Fault tolerance will shine
[Verse 3]
NISQ devices show us hope, near-term algorithms help us cope
But for Shor and true speedup, we need millions working up
Quantum error correction's key, turning noise to harmony
When we reach that golden day, classical will fade away
[Chorus]
SCALE - Stability, Connectivity, Architecture, Logic, Error correction
FAULT - Fidelity, Algorithms, Understanding, Logic gates, Threshold crossing
From the lab to quantum advantage
We must bridge this scaling challenge
[Outro]
The quantum threat is coming near
When scaling challenges disappear
