“…Instead, Kothawala et al [125], Skákala [126,127], Maggiore [128], Liu et al [129], Ren et al [130], Yu and Qi [131] and Bakshi et al [132] argued for a horizon entropy quantum of 2πk. Corishi et al [133,134] proposed 2γ 0 k ln 3, where the Barbero-Immirzi parameter γ 0 is unspecified, Sakalli et al [135] and Rahman [136][137][138] deduced more complex expressions. Liao and Shou-Yong [139] deduced 2πk/3, and Jiang [140] and Aldrovandi and Pereira [141] deduced the value k. The list is not exhaustive but gives an impression of the situation.…”

Experimental and theoretical results about entropy limits for macroscopic and single-particle systems are reviewed. All experiments confirm the minimum system entropy S⩾kln2. We clarify in which cases it is possible to speak about a minimum system entropykln2 and in which cases about a quantum of entropy. Conceptual tensions with the third law of thermodynamics, with the additivity of entropy, with statistical calculations, and with entropy production are resolved. Black hole entropy is surveyed. Claims for smaller system entropy values are shown to contradict the requirement of observability, which, as possibly argued for the first time here, also implies the minimum system entropy kln2. The uncertainty relations involving the Boltzmann constant and the possibility of deriving thermodynamics from the existence of minimum system entropy enable one to speak about a general principle that is valid across nature.
