Entanglement
Quantum entanglement is a unique phenomenon where two or more qubits become correlated in a way that their states are interdependent.
When two qubits are entangled, the measurement of one immediately determines the state of the other — no matter how far apart they are. This connection enables quantum teleportation, quantum cryptography, and superposition-based computation.
Correlated States
Qubit A and Qubit B are linked — measuring one instantly influences the state of the other.

B
When one qubit is measured and rotates in a certain direction, the other qubit instantly knows the connected qubits measurement - demonstrating how entangled qubits are correlated across space.
Einstein on Quantum Entanglement
Einstein famously called entanglement "spooky action at a distance." His skepticism helped shape the foundational debates in quantum theory.
