Macroscopicity
noun ·Rare ·Advanced level
Definitions
- 1 The quality or state of being macroscopic. uncountable
"...it appears to be a small step from (1) and (2) to the identification of a sufficiently large mass with a macroscopic mass and, by analogy, to the consideration as macroscopic any system having sufficiently large quantum numbers associated with it, as well as to accept such macroscopicity as sufficient for classicality."
- 2 A formal measure of the size of a quantum mechanical system or experiment which, while typically larger than the atomic scale, has not undergone decoherence. countable
"Macroscopicities of a representative selection of quantum superposition experiments with mechanical systems plotted against their publication date (adapted from [17] with additional data)."
