Quantum noise refers to unwanted interactions between quantum systems and their environment, causing errors in quantum computations. Unlike classical noise, quantum noise is fundamentally probabilistic and destroys delicate quantum superpositions and entanglement.
⚡ Why Noise Matters
Current quantum computers are NISQ devices (Noisy Intermediate-Scale Quantum). Understanding and simulating noise is crucial for developing error mitigation strategies, designing robust algorithms, and benchmarking quantum hardware performance.
Decoherence
Loss of quantum information due to environmental coupling, destroying superposition
Gate Errors
Imperfect gate operations that deviate from ideal unitary transformations
Relaxation
Energy decay from excited state |1⟩ to ground state |0⟩ over time T₁
Dephasing
Loss of phase coherence between quantum states over time T₂

💡 Key Insight
Quantum noise is not just an engineering challenge—it's fundamental to quantum mechanics. While we can never eliminate noise completely, understanding its mechanisms enables error mitigation, better circuit design, and realistic performance expectations.
