Quantum Entanglement

Quantum entanglement is a fascinating phenomenon in the field of quantum mechanics. It describes the phenomenon where particles become linked together, and the state of one particle instantly correlates with the state of another, regardless of the distance between them.

Key Points

Non-locality: Entangled particles can be separated by large distances, yet the measurement of one particle instantly affects the state of the other.
Spooky Action at a Distance: This term, coined by Albert Einstein, refers to the seemingly instantaneous communication between entangled particles.
Applications: Quantum entanglement has potential applications in quantum computing, quantum cryptography, and quantum teleportation.

How Does It Work?

Quantum entanglement occurs when two or more particles interact in such a way that their quantum states become correlated. This correlation persists even when the particles are separated by large distances.

Measurement: When one of the entangled particles is measured, the state of the other particle becomes determined instantaneously.
Randomness: The outcome of the measurement is random, but the correlation between the particles remains.

Potential Applications

Quantum Computing: Entangled particles can be used to create qubits, the basic unit of information in quantum computers.
Quantum Cryptography: Entangled particles can be used to create secure communication channels that are immune to eavesdropping.
Quantum Teleportation: Entangled particles can be used to transmit information instantaneously over long distances.
