Light does not “think” in any human sense. Still, under the right conditions, it can behave in a way that looks uncannily like a memory system.

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out.

Optical quantum computers are gaining attention as a next-generation computing technology with high speed and scalability. However, accurately characterizing complex optical processes, where multiple ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

For the past decade, quantum computing has struggled to balance promise and practicality. While the world’s most advanced systems remain engineering marvels, they’re bedeviled by the same flaw: the ...

A new microchip-sized device could dramatically accelerate the future of quantum computing. It controls laser frequencies with extreme precision while using far less power than today’s bulky systems.

In an industry where timelines are often fuzzy and subject to revision, quantum computing company PsiQuantum has set itself an aggressive target. The California-based startup has committed to building ...

NTT and OptQC aim to build a 1-million qubit quantum computer based on light, rather than electricity, to enhance reliability, scalability and practicality. Use cases for a practical optical quantum ...

An international team of researchers has synthesized a carbon chain molecule with a never-before-seen electronic twist and used quantum computing methods to confirm its exotic structure. The molecule, ...

The latest trends in software development from the Computer Weekly Application Developer Network. Sometimes classed as a Japanese startup, OptQC works with optical photonic technologies to develop a ...
