Which outcome limits maintaining quantum key distribution entanglement?

💡 Explanation

Photon decoherence causes loss of entanglement via wavefunction collapse because environmental interactions disrupt quantum states; therefore error rates increase, rather than superposition enhancement or sustained correlated signal gain as external noise increases.

• Which outcome occurs when microwave radiation encounters a Faraday cage?
• Which outcome is seen when a shape-memory alloy (SMA) wire, pre-strained at low temperature, is heated past its austenite transition temperature?
• Which mechanism enables stable electron flow despite dislocations in metals?
• Which outcome occurs when a massive star exhausts silicon?
• Within a hydrogen fuel cell, which outcome prematurely halts electricity production?
• Which consequence results when quantum tunneling fails in photovoltaic cells?
