What of importance of superposition in quantum computing? What I understood is we have two states |0> and |1> which represent logical 0 and 1 . So the mixed state can be given by the combination of logical operators like OR, AND and NOR Etc. For example 1/3 |0>+2/3 |1> The particle...

H= [E_a 0 0 ; 0 E_b 0; 0 0 E_c] Psi= [a; b;c]

So if states are degenerate i can have H= [E_a 0 0 psi = [a 0 Eb 0 b 0 0 EC] c]

SO it means that indvdually H= E (|a><a|) for state a and for all three states i can write H= E (|a><a|+|b><b|+|c><c|) am i right?

I am new to quantum physics. My question is how to write the Hamiltonian in dirac notation for 3 different states say a , b , c having same energy. I started with Eigenvaluee problem H|Psi> = E|psi> H = ? for state a? SO it means that indvdually H= E (|a><a|) for state a and for all three...
