If the superpositions of the sphere can then be measured before it decoheres and snaps to just one location, that would be an unprecedented success.

These are superpositions of ones and zeros and are represented by, for example, the direction of spin (with respect to a magnetic field) of a particle such as an electron.

However, the cat (or, rather, subatomic particles that behave like the cat) has proved hard to hunt down in practice because such superpositions of states are fragile and easily disrupted phenomena.
