The term you probably heard was superposition.
The information of a system involving particles is limited by mathematics in a stange way. If you dont know the position of a particle with certainty by measurent, its location becomes defined by a mathematical function, literally as fragments of a particle scattered over different locations in space. "one location" as we know it does not materialize until the position is measured and the waveform is "collapsed". Shroidinger's cat is a reasonable metaphor to explain it.
The math involved is heisenberg's uncertainty principle and i would be careful what you read out there about quantum mechanics because theres a lot of utter nonsense out there.
A bit misleading because wave function collapse only pertains to specific, growingly rejected interpretations of quantum mechanics.
