## Main Question or Discussion Point

In a 2 level quantum system, should I consider the states

[tex] |0> [/tex]

and

[tex] |1|> [/tex]

to be qubits by themselves?

Or is only the SUPERPOSITION of these two states,

[tex] \alpha |0> + \beta |1> [/tex]

considered to be a qubit?

[tex] |0> [/tex]

and

[tex] |1|> [/tex]

to be qubits by themselves?

Or is only the SUPERPOSITION of these two states,

[tex] \alpha |0> + \beta |1> [/tex]

considered to be a qubit?
