Bad Qubits — Learn Quantum by Doing

Multiple choice

Alice and Bob share an entangled pair. Alice measures her qubit in New York; Bob holds the other in Tokyo. Which statement is correct?

Bob can read Alice's result without any further communication, enabling faster-than-light signaling.
Their outcomes are correlated, but neither can use the shared pair alone to send a message faster than light.
Measuring one qubit has no effect on the joint state; the qubits were never really linked.
Alice's measurement instantly transmits a bit of her choosing to Bob.
