Beyond XOR: Taming Circuit Complexity with Simple Extensions

24.11.2025 by Ray Dalio

The architecture of optimal circuits computing $XOR_6$ reveals a fundamental relationship between Red’kin and DeMorgan bases: while every circuit optimized within the Red’kin framework also functions optimally in the DeMorgan base, the converse is not true, yet both share identical arrangements of $XOR_2$ building blocks.

New research reveals a fixed-parameter tractable approach to determining if a Boolean function is a simple extension of another, shedding light on the fundamental challenges of circuit complexity.

Taking Control of Your Health Data: A Blockchain Blueprint

24.11.2025 by Ray Dalio

The system architecture decouples authorization from data storage, securing content through off-chain encrypted storage while verifying integrity via a $SHA-256$ digest-calculated from the concatenation of content, timestamp, nonce, and authorization data-ensuring both confidentiality and verifiable access.

A new framework leverages blockchain technology to put patients at the center of their electronic health record management, enhancing security and privacy.

Quieter Qubits: New Design Boosts Quantum Error Correction

24.11.2025 by Ray Dalio

Neural networks, when tasked with decoding data subject to varying levels of information leakage-quantified as $L~1test$-demonstrate a surprising robustness, achieving comparable performance regardless of the leakage rate at which they were initially trained, though identifying optimal networks in scenarios prioritizing multiple, potentially conflicting metrics-like parameters $\gamma$ and A-proves more complex and less predictable than when focusing on a single, well-defined target.

Researchers have developed an innovative approach to reducing errors in superconducting qubits by integrating a leakage reduction unit directly into the measurement process.

Untangling Hypergraph States: A New Approach to Stabilizer Construction

24.11.2025 by Ray Dalio

Hypergraphs offer a more economical representation of completeness than traditional graphs-while a graph requiring at least three edges to fully connect three vertices can be expressed with a single hyperedge-and this principle extends to quantum states, allowing a 3-uniform complete hypergraph with four vertices to elegantly represent the complex GHZ state.

Researchers have developed a method for expressing the stabilizers of complex hypergraph states using only local operators, opening new avenues for understanding their non-local properties.
