Putting the squeeze on quantum information | ScienceDaily

In the quantum world it’s more complicated.

A qubit can be in a “superposition” between both zero and one until you measure it, at which point it collapses to either a zero or a one. Not only that, but you can extract different values depending on how you make the measurement.

Measured one way, a qubit might reveal a value of either zero or one. Measured another way it might show a value of either plus or minus.
