Undergrad Is the holographic principle based on fuzzy logic?

Click For Summary
Physicist Craig Hogan's research focuses on the holographic principle, proposing that the universe may function as a hologram, with experiments like "The Holometer" designed to measure quantum fluctuations at the Planck scale. The term "fuzzy" in this context refers to the imprecise nature of certain measurements, not to fuzzy logic as a governing principle. The discussion clarifies that Hogan is not introducing the holographic principle but rather building on Leonard Susskind's earlier work. The Holometer aims to test various models of quantum geometry, providing insights beyond current gravitational wave observations. Overall, the conversation emphasizes the distinction between fuzzy position information and fuzzy logic in quantum mechanics.

TL;DR
Are fuzzy quantum fluctuations governed by fuzzy logic?
Physicist Craig Hogan has proposed that the universe is based on holographic principle. To prove that the universe is a "hologram" he (and other physicists) have designed an experiment named "The Holometer" to measure quantum fluctuations that would become fuzzy at Planck scale. (https://arxiv.org/pdf/1611.08265.pdf)

But, what does "fuzzy" exactly mean? Does it mean that quantum mechanics would behave according to fuzzy logic at that scale?

No, it is not related to fuzzy logic. It simply means that the fuzzy thing is not fundamental. For example, where exactly is the boundary of the human body? That is a question with a fuzzy answer, since a human being is not a fundamental thing. In contrast, electrons, protons and neutrons are fundamental things (even then, maybe not, if one looks at a fine enough scale).

What he is talking about has absolutely nothing to do with "fuzzy logic". He's talking about fuzzy position information.

Also, he is not "proposing" the holographic principle, he's just using a theory proposed by Leonard Susskind 25 years ago.

EDIT: I see atyy beat me to it.

As stated. While a few years since reading Susskind (and Weinberg), the 'cosmic landscape', holographic principle and the cited article describe geometry. See the last sentence of the abstract [bold added]:

The Holometer in current and future configurations is projected to provide precision tests of a wide class of models of quantum geometry at the Planck scale, beyond those already constrained by currently operating gravitational wave observatories.
 
Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
