Toward a Quantum Theory of Humor

Weirdest paper I’ve seen on quant-ph in a long time:

Toward a Quantum Theory of Humor

This paper proposes that cognitive humor can be modeled using the mathematical framework of quantum theory. We begin with brief overviews of both research on humor, and the generalized quantum framework. We show how the bisociation of incongruous frames or word meanings in jokes can be modeled as a linear superposition of a set of basis states, or possible interpretations, in a complex Hilbert space. The choice of possible interpretations depends on the context provided by the set-up vs. the punchline of a joke. We apply the approach to a verbal pun, and consider how it might be extended to frame blending. An initial study of that made use of the Law of Total Probability, involving 85 participant responses to 35 jokes (as well as variants), suggests that the Quantum Theory of Humor (QTH) proposed here provides a viable new approach to modeling humor.

My review: the paper is not funny.

Dephasing-controlled particle transport devices

We study the role of dephasing in transport through different structures. We show that interference effects invalidate Kirchhoff’s circuit laws in quantum devices and illustrate the emergence of Ohmic conduction under strong dephasing. We present circuits where the particle transport and the direction of rectification can be controlled through the dephasing strength. This suggests the possibility of constructing molecular devices with new functionalities which use dephasing as a control parameter.
