Quantum Recurrence: A New Approach to Image Classification

15.12.2025 by Ray Dalio

The framework leverages all combinations of $c$, $x$, and $y$ qubits as inputs to quantum recurrent neural network cells, where $x$ and $y$ specifically encode positional information, enabling a comprehensive exploration of quantum state space for image analysis.

Researchers are exploring the potential of quantum computing to enhance image recognition using recurrent neural networks and a novel image encoding technique.

Mimicking Quantum Randomness with Classical Jitter

15.12.2025 by Ray Dalio

Through computational permutation, a digital replication of optical coherent states precisely mirrors the characteristics of a Poisson distribution with $μ=100$ and variance $σ^2≈100$, demonstrating that statistical properties of quantum phenomena can be accurately reproduced via algorithmic processes.

Researchers have shown that high-quality random numbers, typically generated by quantum processes, can be faithfully reproduced using the inherent timing variations within standard computer systems.

Squeezing Every Drop from Bayesian Data

15.12.2025 by Ray Dalio

The study demonstrates that estimates of $log(z)$ derived from nested sampling (NS) converge with increasing numbers of live points, achieving accuracy comparable to MorphZ estimates-particularly those utilizing second- and third-order approximations-as evidenced by the diminishing root-mean-square error relative to the true value with greater computational effort.

A new method, MorphZ, dramatically improves the accuracy and efficiency of evidence estimation in complex Bayesian analyses.

Why Some AI Can Reason, and Others Can’t

15.12.2025 by Ray Dalio

The study demonstrates that BERT, leveraging an encoder-only architecture, exhibits consistent geometric transformations throughout multi-step reasoning-a preservation of logical structure-while decoder-only models like Qwen display increasing curvature drift, suggesting a breakdown in that same logical consistency, findings which corroborate a geometric framework for understanding reasoning processes as described by zhou2025geometry.

New research reveals a fundamental architectural limitation in decoder-only models when it comes to complex causal reasoning and adapting to changing data.
