1. Is the state ( 1/2 (|00|11 )) entangled?

2) A two-qubit system is in the state |=16|01+56|10. Is the state normalized? An gate is applied to the second qubit. After this is done, what are the possible measurement results if both qubits are measured, and what are the respective probabilities of each measurement result?

3. Find the Adjoint of the operator = 2|01| |10|.

4. Does the matrix represent a density operator?
