Squeezing More From Your Model: A Smarter KV Cache

08.12.2025 by Ray Dalio

The study demonstrates that both Mistral and Llama models exhibit a layer-dependent relative Frobenius approximation error, with performance fluctuations across layers impacting the accuracy of key matrices - $𝐊$, $𝐐$, $𝐕$, and $𝐊𝐐^{\top}$ - as well as the attention layer output.

Researchers have developed a new technique to compress the memory footprint of large language models without sacrificing performance.

Tuning In: Cost-Effective Phase Stabilization for Quantum Key Distribution

08.12.2025 by Ray Dalio

A quantum communication system leverages a shared fiber for both quantum key distribution and classical synchronization, simultaneously employing frequency-matched light to precisely measure and correct frequency differences-induced by independent laser sources-through beat-note interference, thereby enhancing the accuracy and stability of the quantum channel.

A new photodiode-based technique dramatically simplifies laser phase stabilization, paving the way for practical and scalable quantum communication networks.

Harnessing the Quantum Dice: A New Framework for Random Number Generation

08.12.2025 by Ray Dalio

Atomic coherence demonstrably impacts intrinsic randomness in temporal measurements, with the degree of this influence-quantified by the $l_1$ norm of coherence ranging from 0 to 1-shifting from single-photon detection ($n=1$) to a modulation of extractable bits, indicating that randomness isn’t an inherent property but emerges from the system’s internal coherence.

Researchers have developed a rigorous quantum information-theoretic approach to understanding and securing random number generators based on the inherently unpredictable nature of spontaneous emission.

Erasing the Line: New Control Over Quantum Memory

08.12.2025 by Ray Dalio

The system’s initial high entropy $ \rho_{B} $ diminishes through correlated local measurements performed by assisting parties, as demonstrated by the reduction in residual entropy-visually represented by a shift from red to blue and purple-though complete erasure is achieved only when one party exhibits a demonstrably stronger correlation, indicating exclusive thermodynamic control over the decaying system.

Researchers have demonstrated a novel method for selectively erasing quantum information, offering new possibilities for secure communication and robust quantum systems.

Simulating Superconductivity with a New Computational Lens

08.12.2025 by Ray Dalio

The system exhibits a diminishing sensitivity to lattice spacing, as evidenced by the near-flat trajectory of qubit frequency with decreasing lattice size-a behavior quantified by a quadratic dependence of the lattice spacing error and confirming the validity of the continuum limit approximation defined in $Eq.(IV.1)$.

Researchers are leveraging lattice field theory and Monte Carlo methods to provide a more accurate and scalable approach to modeling complex superconducting circuits.

Beyond Classical Limits: Quantum Communication for Multiple Senders

08.12.2025 by Ray Dalio

Figure 1: Caption: A simulation of a black hole accreting matter from a companion star. The simulation incorporates effects from general relativity, including gravitational lensing and time dilation. The color scale represents the energy density of the accreting gas, with brighter colors indicating higher energy. The relentless pull of the black hole distorts spacetime, bending light and stretching time itself as matter spirals inward, a visual testament to the fragility of any model attempting to fully grasp the abyss.

New research demonstrates the potential for quantum systems to outperform classical methods in scenarios where multiple parties communicate with a single receiver.

Quantum Authentication: A New Proof of Identity

08.12.2025 by Ray Dalio

A three-round quantum interactive proof game establishes communication through quantum operations-$Z_1Z_{1}$, $Z_2Z_{2}$, and $Z_3Z_{3}$-with the prover utilizing internal registers $P_0P_{0}$ and the verifier employing $V_0V_{0}$ and $V_1V_{1}$, exchanging messages $X_0X_{0}$ in round one, $Y_0Y_{0}$ in round two, and $X_1X_{1}$ in round three to validate a proof.

Researchers have developed a novel quantum protocol that leverages zero-knowledge proofs to establish a secure and efficient method for verifying digital messages in emerging quantum networks.

Seeing Inside the Quantum Black Box

08.12.2025 by Ray Dalio

The architecture for quantifying system complexity-implemented on the Miyabi supercomputer and mdx platform-reveals how observability, rather than raw computational power, dictates a system’s capacity to navigate uncertainty and respond to unforeseen challenges.

New observability tools are critical for understanding and optimizing the complex workflows driving the next generation of quantum-centric supercomputing applications.
