[Verse 1]
In silicon chambers where qubits dream
Decoherence whispers break the scheme
Ten microseconds till the magic dies
While thermal noise corrupts quantum ties
Error rates climbing past the threshold
Our fragile states refuse to hold
[Chorus]
Scale the mountain, qubit by qubit
Fault tolerance is the summit we seek
NISQ devices show us glimpses
But advantage needs a thousand-fold leap
Error correction codes protecting
Surface codes detecting every mistake
From lab bench prototypes to quantum supremacy
How many gates until the breakthrough breaks?
[Verse 2]
Connectivity graphs map the maze
Two-qubit gates in limited ways
Nearest neighbors sharing entangled fate
While distant qubits must communicate
Through chains of SWAP operations costly
Topology dictates what's possible, mostly
[Chorus]
Scale the mountain, qubit by qubit
Fault tolerance is the summit we seek
NISQ devices show us glimpses
But advantage needs a thousand-fold leap
Error correction codes protecting
Surface codes detecting every mistake
From lab bench prototypes to quantum supremacy
How many gates until the breakthrough breaks?
[Bridge]
Logical qubits need hundreds of physical
Overhead crushing computational dreams
Threshold theorem promises salvation
If we cross the valley where error rate screams
One part in ten thousand might save us
From the classical simulation abyss
[Verse 3]
Calibration drifts with morning coffee
Yesterday's parameters now faulty
Control pulses fighting crosstalk demons
While gate fidelities demand better reasons
Million-qubit machines seem distant
When current chips barely stay consistent
[Final Chorus]
Scale the mountain, qubit by qubit
Fault tolerance is the summit we seek
From NISQ to cryptanalytic power
The exponential gap we must breach
Error correction codes protecting
Concatenated schemes deflecting decay
From lab bench struggles to quantum advantage
Count the milestones marking the way
[Outro]
In the race between error and correction
Lies the future of quantum direction
