[Verse 1] In the quantum realm where particles play Superposition holds its mysterious sway Electrons spinning up and down at once Till measurement collapses all their stunts But fragile states need isolation pure One stray photon makes the magic blur [Chorus] Coherence keeps the quantum dream alive Decoherence makes the weirdness die Environment whispers break the spell Temperature, noise, and photons tell The secret states they cannot hide When classical worlds and quantum collide [Verse 2] Entangled pairs across the void stay linked Their fates together perfectly synced But vibrations from the outside creep Destroying correlations they would keep The warmer it gets, the faster they fall Decoherence conquers one and all [Chorus] Coherence keeps the quantum dream alive Decoherence makes the weirdness die Environment whispers break the spell Temperature, noise, and photons tell The secret states they cannot hide When classical worlds and quantum collide [Bridge] Microseconds, nanoseconds tick away Quantum advantage starts to fray Error correction fights the decay But entropy will have its way Schrödinger's cat becomes just dead or living When decoherence stops forgiving [Verse 3] Quantum computers need their states pristine Near absolute zero keeps them clean Shielded chambers, vacuum-sealed tight Protecting qubits from ambient light Every interaction steals the phase As quantum magic quickly fades [Final Chorus] Coherence keeps the quantum dream alive Decoherence makes the weirdness die Guard the states with all your might From thermal chaos, sound, and light The quantum edge will slip away When decoherence wins the day [Outro] Fragile, fleeting, quantum states Coherence controls their quantum fates
