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 ...

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 ...

Researchers at Harvard have created a groundbreaking metasurface that can replace bulky and complex optical components used in quantum computing with a single, ultra-thin, nanostructured layer. This ...

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 ...

There are few technologies more fundamental to modern life than the ability to control light with precision. From fiber-optic communications to quantum sensors, the manipulation of photons underpins ...

For all the hype surrounding quantum computers, the technology can sometimes appear to be a solution in search of a problem. Scientifically impressive, but not yet obviously useful in the real world.
