Please clarify the following statement in Dense Coding
Suppose Alice wants to send Bob information. Each of them has been sent each of the qubits of the Bell state in advance. Suppose Alice has the first qubit and Bob has the second.
|Φ+⟩ = 1/√2 (|00⟩ + |11⟩)
*Reference: Dense Coding Topic QUANTUM COMPUTING From Linear Algebra to Physical Realizations Mikio Nakahara*
Q1) What are the individual qubits received by Alice and Bob?
Q2) If Alice wants to send her first Qubit to Charles then is it possible to send her individual qubit? (or is it required to send complete |Φ+⟩?)
