2. Consider a 2-Cbit system, that is, (a) Verify the expression for the SWAP operator S10 by applying S10 to each of the four possible Cbits. (b) Verify the expression for the cNOT operator C,o by applying C1o to each of the four possible Cbits Verify the identity (c) C01 S10 C10S10 by applying this form of Co1 to each of the four possible Cbits
