Decoding Quantum Resilience: A Neural Network Approach to Error Correction

10.12.2025 by Ray Dalio

The SAQ-Decoder architecture establishes a framework where complex relationships emerge not from centralized design, but from the interplay of local, self-organizing components-a system where order arises from inherent rules rather than imposed structure, mirroring how intelligence itself may unfold.

Researchers have developed a new neural decoder that significantly improves the performance of quantum error correction, bringing fault-tolerant quantum computing closer to reality.

Quantum Cloud Coordination: Meeting Deadlines in a Distributed World

09.12.2025 by Ray Dalio

A near-term quantum cloud workflow manages user circuits by decomposing them into manageable subcircuits, scheduling these on available quantum processing units while adhering to constraints regarding qubit count, circuit depth, and execution precedence, and ultimately reconstructing final results through classical post-processing - a process enabling complex quantum computations within the limitations of current hardware.

As quantum computing scales, efficiently scheduling circuits across multiple processors becomes critical for maximizing throughput and minimizing execution time.
