Let Evolution Design Your Quantum Autoencoder

What if we could let evolution design quantum circuits that compress data? This paper explores exactly that with quantum autoencoders—models that shrink high‑dimensional quantum or classical data while keeping the important bits.

The authors introduce a neural architecture search framework powered by a genetic algorithm. Instead of hand‑crafting circuits, their method evolves variational quantum circuit (VQC) designs—choosing gates, arranging layers, and tuning parameters—to build high‑performing hybrid quantum‑classical autoencoders for data reconstruction.

Automates circuit design to cut trial‑and‑error.
Evolutionary search helps avoid getting stuck in local minima.
Demonstrated on image datasets; shows promise for efficient feature extraction on noisy, near‑term quantum hardware.

Why it matters: a step toward push‑button QML, where architectures adapt to data and hardware limits with minimal human tweaking.

Beyond URLs: Metadata That Makes LLMs Train Faster

Smarter LLMs, Faster—thanks to metadata What if training a large language model didn't just rely on text, but on the context around it? This study shows that adding fine-grained metadata—not just URLs—can meaningfully speed up pretraining and improve quality. * Beyond URLs: detailed quality signals (e.

Escaping the Verifier: Learning to Reason via Demonstrations

LLMs can learn to reason—without task verifiers Many real-world problems don’t have automatic checkers to grade answers, even though we have lots of expert solutions. RARO (Relativistic Adversarial Reasoning Optimization) shows how to train reasoning skills from those examples alone. How it works: * A policy (the model) tries

VacuumVLA: A Two-in-One Robot Hand That Grips and Suctions

Robots guided by Vision-Language-Action (VLA) AI are getting better at everyday tasks—but most still use simple two-finger grippers. That limits them on smooth, flat, or handleless objects. VacuumVLA is a low-cost robot hand that merges a standard two-finger gripper with a vacuum suction cup. The robot can switch between
