[Verse 1] In quantum realms where particles play Each path they take has amplitude's sway Not just the chance of where they'll be But complex numbers dancing free Magnitude squared gives probability But before that step, there's mystery [Chorus] When waves collide, they interfere Add them up and watch them steer Constructive boost or destructive fade Quantum interference parade Amplitudes can cancel out That's what quantum's all about [Verse 2] Two slits await an electron's flight Each path contributes to the sight Through slit one gives amplitude A Through slit two brings a different way Add them up before you square Interference patterns everywhere [Chorus] When waves collide, they interfere Add them up and watch them steer Constructive boost or destructive fade Quantum interference parade Amplitudes can cancel out That's what quantum's all about [Bridge] Same phase means they reinforce Opposite phase they change their course Zero sum when they're reversed Matter waves are interspersed Not just particles alone Wave nature clearly shown [Verse 3] Dark fringes where the waves destroy Bright bands where they employ Constructive adding of their might Destructive canceling their light Probability can disappear When quantum interference is here [Chorus] When waves collide, they interfere Add them up and watch them steer Constructive boost or destructive fade Quantum interference parade Amplitudes can cancel out That's what quantum's all about [Outro] Matter waves like light behave Interference patterns pave The way to quantum's deepest truth Amplitude's the quantum proof
