Negative probabilities
Yuri Gurevich, Vladimir Vovk
TL;DR
This paper discusses the concept of negative probabilities using Wigner's quasiprobability distribution as an example, exploring their potential role in the foundations of probability theory.
Contribution
It introduces the idea of negative probabilities and demonstrates their application in the context of quantum mechanics foundations.
Findings
Negative probabilities can be meaningfully interpreted in quantum contexts
Wigner's distribution exemplifies how negative values arise in quasiprobability distributions
Negative probabilities may provide insights into quantum foundations
Abstract
We explain, on the example of Wigner's quasiprobability distribution, how negative probabilities may be used in the foundations of probability.
