Quantum entanglement, a cornerstone of quantum mechanics, describes a phenomenon where particles become interconnected, such that the state of one instantly influences the state of another, regardless of distance. This "spooky action at a distance," as Einstein famously called it, challenges classical notions of locality and realism.
Key Characteristics
- Instantaneous Connection: Entangled particles exhibit correlations that defy classical physics.
- Non-Local Influence: Changes to one particle affect its entangled partner instantly, even across vast distances.
- Superposition & Measurement: Entangled systems exist in superposition until measured, at which point their states collapse into definite values.
Applications & Implications
- Quantum Computing: Enables qubits to process information in parallel through entanglement.
- Quantum Cryptography: Secures communication via entangled particle pairs (e.g., Quantum Key Distribution).
- Fundamental Research: Deepens understanding of quantum theory and spacetime.
