Two qubit entanglement

Hello,
Does anybody know a two qubit gate which entangle this qubits?
I am looking for a tool which help me get average from two or more qubits. I think I could treat that entanglement as an avarage, because all qubits will have same values when I observe anyone.

Thanks for responses,
Łukasz

Edit:
I think about universal entaglement gate which do entanglement state for every two qubits, I have started thinking if that gate even exists.

CNOT

will entangle almost all states

Two qubit entanglement

The two qubits can be prepared in an entangled state by using the Hadammard and CNOT gate. See Quantum Computation and Quantum Information by Michael A. Nielsen and Isaac L. Chuang.
