A Deterministic Tree Map That Acts Like Quantum Randomness

The short version

This paper proposes a way to get random-looking numbers from a fixed rule instead of true chance. The authors use a tree-shaped number system and a special map to turn it into evenly spread points on a line.

Why randomness matters

Random numbers from quantum devices help keep messages secret, run computer simulations, and fix errors in quantum computers. Today, people assume this randomness cannot be predicted. This paper asks: could the randomness come from a fixed geometric rule instead?

The tree and the map

The authors use a branching tree where each level splits into three branches. They pick the number three because of a known change-point in a physics model. The tree has three levels, giving twenty-seven endpoints. The Monna map is a rule that flips the tree's number system into ordinary numbers on a line between zero and one. Each endpoint lands on a different point, spaced exactly evenly. The map preserves the even spread: no point gets crowded.

What was calculated

The authors compute how spread out the results are, using a standard measure from random-number studies. The result is about five bits. This matches what you would get from a truly even random spread. They also find a tiny wobble in the pattern. This wobble comes from using a finite tree rather than an endless one. Its size is small, about four parts in a hundred. The authors treat this wobble as a guess about what might show up in precise tests, not as something already seen.

What this does not show

The paper does not build or test any real device. It does not explain how quantum entanglement would work in this system. It does not prove that noise in real hardware would let the pattern survive. The wobble size is assumed, not derived from deeper rules. The entropy value alone cannot prove the map is at work, since many systems can give the same number.

What could prove or disprove this

A real test would build a device that walks through all twenty-seven states and applies the map. If the output lacks the predicted wobble above a one-percent level, the specific claim fails. If the output drifts from the even spread, the claim also fails. The authors rate this idea at the concept stage only.

In the paper's words

Quantum‑mechanical randomness underlies cryptographic key generation, Monte Carlo simulation, and error‑corrected quantum computation. Existing explanations treat the Born rule as a fundamental stochastic postulate, leaving the origin of randomness opaque. A specific gap is the absence of a deterministic geometric mechanism that reproduces the observed statistical distribution of measurement outcomes.

  1. Compute the leaf weight: $$ w = \frac{1}{p^{k}} = \frac{1}{27}\approx0.037037. $$ Compute the entropy: $$ H_{\text{leaf}} = \log_{2}(27) = \frac{\ln 27}{\ln 2}. $$ Step‑by‑step: $$ \ln 27 = \ln(3^{3}) = 3\ln 3 \approx 3\times1.09861229 = 3.29583687. $$ $$ \ln 2 \approx 0.69314718. $$ $$ \frac{3.29583687}{0.69314718} \approx 4.7548875. $$ Thus $$ H_{\text{leaf}} \approx 4.7548875\ \text{bits}. $$

  2. The normalization factor is the mean density: the $27$ intervals of length $1/27$ carry total weight $1$, so the average height of the discrete density is $1/(1/27)\cdot(1/27)=1$ per unit interval.

    from 4.3. Log‑Periodic Term Amplitude
  3. The entropy of the uniform leaf distribution for a depth‑$3$ $3$‑adic tree is $H=4.7548875$ bits, identical to the Shannon entropy of a uniform real interval partitioned into $27$ equal parts.

    from 5. Results
  4. The entropy test alone is weak, because any device that outputs each of the $27$ symbols equally often reproduces $H=4.7548875$ bits regardless of mechanism; the discriminating prediction is therefore the log‑periodic component R3, whose absence at the stated threshold would refute the specific projection model rather than determinism in general.

  5. One would measure the output distribution over $10^{6}$ trials and compute the empirical Shannon entropy.

  6. The test would use a firmware implementation of $\varphi$ over the digit registers $(a_{0},a_{1},a_{2})$, driven by a counter that cycles through all $27$ triples; the empirical entropy would be computed as $\hat{H}=-\sum_{i}\hat{P}_{i}\log_{2}\hat{P}_{i}$ with $\hat{P}_{i}=n_{i}/10^{6}$, and the empirical occupancy of each of the $27$ bins would be compared with the expected $10^{6}/27\approx37037$ counts per bin.

How it is done

  1. Using the Shannon‑entropy definition from quantum‑random‑number‑generator literature [1] and the phase‑transition condition $p=3$ for the $p$‑adic Potts model [2], we compute the entropy of the projected uniform leaf distribution for $p=3$ and depth $k=3$.

  2. Formal definition of the Monna map $\varphi$ for a $p$‑adic tree and proof of its measure‑preserving property (Section 3).

    from 1. Introduction
  3. Quantum‑hardware engineers and cryptographic system designers could employ the deterministic projection model to replace stochastic QRNG modules with deterministic $p$‑adic tree processors that reproduce the same statistical distribution, though the resulting numbers remain algorithmically predictable as a pseudo‑random analogue per [1].

    from 7.1. Potential Users and Design Changes
  4. A prototype could enumerate the $27$ leaf states of a depth‑$3$ $3$‑adic tree and implement the Monna map in firmware.

What would falsify it

  1. A single observation that would falsify the main claim is a statistically significant deviation from the predicted uniform distribution or entropy value in a controlled hardware test of the Monna‑projection device.

    from 6.2. Falsifiability
  2. The entropy test alone is weak, because any device that outputs each of the $27$ symbols equally often reproduces $H=4.7548875$ bits regardless of mechanism; the discriminating prediction is therefore the log‑periodic component R3, whose absence at the stated threshold would refute the specific projection model rather than determinism in general.

  3. Presentation of a log‑periodic modulation term $\rho(x)=1+\epsilon\cos\!\bigl(2\pi\log_{3}x\bigr)$ with amplitude $\epsilon\approx0.03704$ arising from finite‑depth truncation; the term is discussed as a theoretical prediction without asserted observability.

Where the claim stops

  1. The analysis assumes a finite depth $k$; infinite‑depth limits recover exact uniformity but are unattainable in physical hardware.

    from 6.1. Limitations
  2. The model treats measurement outcomes as deterministic projections; it does not address dynamical decoherence mechanisms beyond the static geometry.

    from 6.1. Limitations
  3. Quantum random‑number generators (QRNGs) are commercially available, and surveys of the field identify entropy as the central figure of merit for their output quality [1], while the underlying randomness is assumed to be fundamentally indeterminate.
