Being every possible answer at once, until someone rude checks.
means A quantum system existing in a combination of multiple states simultaneously, rather than settling into just one, until a measurement forces it to commit.
from From Latin super- 'above/over' plus positio 'placement, position' — the plain idea of 'placing one thing on top of another.' Mathematicians and physicists borrowed this ordinary word for the principle that waves (or wave-like quantum states) can be laid on top of each other and added together, their combination itself being a valid state. Quantum mechanics inherited the term in the early 20th century to describe how a particle's possible states can overlap and coexist mathematically — not metaphorically stacked, but genuinely summed — until a measurement collapses the stack into one outcome.
- not mixing
- not a blend, all states fully real simultaneously
- measurement
- observation forces one outcome, collapses the rest
- schrodinger's cat
- thought experiment mocking the idea, not proving it
- real use
- qubits exploit this for parallel computation
