What is entanglement in quantum computing?
a) A physical connection between quantum computers
b) A phenomenon where two qubits are correlated, such that the state of one determines the state of the other, no matter the distance between them
c) A way to store quantum data
d) A form of classical computing
Answer:
b) A phenomenon where two qubits are correlated, such that the state of one determines the state of the other, no matter the distance between them
Explanation:
Entanglement is a unique property of quantum systems where two qubits become linked, and the state of one instantly influences the state of the other, even across long distances.
