Gammaquants

Gammaquants are a theoretical construct in quantum information theory and generalized probabilistic theories that aim to describe partially quantum information with a continuous deformation parameter. The concept introduces a gamma parameter, typically in the range (0,1], that interpolates between classical bits and conventional quantum bits. When gamma = 1, the formalism reduces to standard quantum information with familiar qubit or qudit states. As gamma approaches 0, the behavior tends toward classical-like statistics, capturing a spectrum of “partial quantumness” between classical and quantum regimes.

Mathematically, a Gammaquant is described by a state-parameter pair (psi, gamma), where psi is a normalized state in a finite-dimensional Hilbert space and gamma modulates the probability rule used to extract measurement outcomes. The gamma-deformed rule reduces to the standard Born rule at gamma = 1, while other gamma values yield deformed probability assignments that resemble generalized or non-extensive statistics. Within this framework, gamma-preserving operations extend the notion of quantum channels, and gamma-entanglement becomes a resource that can be quantified, transformed, or consumed under a gamma-generalized set of operations.

Gammaquants are studied as part of efforts to understand how deviations from standard quantum mechanics might influence information processing, decoherence, and nonlocal correlations. They also serve as a bridge to generalized probabilistic theories, offering a way to compare quantum and classical information processing within a single deformation parameter. At present, Gammaquants remain primarily theoretical, with discussions focused on formal consistency, potential operational interpretations, and possible experimental tests of gamma-deformed statistics.
