What's happening?
The qubit starts in a pure superposition state (green vector). As it interacts with the environment (red noise particles), the quantum coherence is lost. The vector shrinks and wobbles, representing the loss of phase information and the transition to a classical mixed state.
Key Concepts:
• T₁ (Relaxation): Energy decay time
• T₂ (Dephasing): Phase coherence time
• Environmental noise: Thermal fluctuations, electromagnetic interference
• Mixed state: Classical probability distribution
