Compact flat-lens system can generate nondiffracting bottle beams

Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long ...

Small quantum system outperforms large classical networks in real-world forecasting

Can a handful of atoms outperform a much larger digital neural network on a real-world task? The answer may be yes. In a ...

Quantum computers need vastly fewer resources than thought to break vital encryption

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require ...

Spinal cord stimulator stays rigid for surgery, then softens inside the body

What if chronic diseases, which are difficult to treat with medicine alone, could be managed with electricity? As ...

A Distributed Cloud Storage and Medical Image Encryption Algorithm Application: Medical Image Sharing System

Abstract: This paper proposes a new chaotic system, and experimental analysis shows that its Lyapunov exponent can reach up to 6.85, demonstrating excellent chaotic performance. It is highly suitable ...
