Analog optical computer for AI inference and combinatorial optimization

Experimental set-up

The key components of our experimental set-up are shown in Fig. 1a and Extended Data Fig. 1.

Optical subsystem

The optical subsystem performs matrix–vector multiplication. The basic components are the optical sources (input…

Assembly theory and its relationship with computational complexity

Overview of complexity measures

The ontology underlying AT as a theory of physics is different than that of the theory of computation, see Table 1. In what follows, we compare AT to computational and information-theoretic approaches to quantifying…

Innovative Broadband Optical Fibers Could Improve Telecommunications

Instead of a traditional solid glass core, the newly-developed optical fibers feature a core of air surrounded by a meticulously engineered glass microstructure to guide light. This design increases transmission speeds by 45% and allows more…
