Atomic, molecular and optical (AMO) physics explores the quantum behaviour of electrons, atoms and light, and their mutual interactions across energy, length and time scales. In atoms and molecules, ...

Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical ...

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 ...

The research demonstrates a practical method for overcoming a long standing bottleneck in quantum computing, bringing closer ...

Light does a lot of work in the modern world, enabling all types of information technology, from TVs to satellites to ...

Glass nanostructures etched using high-intensity femtosecond laser pulses promise to keep vast quantities of data safe for billions of years, describe Peter Kazansky, Ausra Cerkauskaite and Rokas ...

In this Physics World Focus on Optics & Photonics you’ll find an interview with the healthcare photonics lead at the UK’s Centre for Process Innovation, and a report on a pan-European effort to ...

A research team at Shanghai Jiao Tong University has unveiled Optics GPT, described as the world's first large language model ...

Researchers show that precisely layering nano-thin materials creates excitons -- essentially, artificial atoms -- that can act as quantum information bits, or qubits. By taking two flakes of special ...

Atomic clocks record time using microwaves at a frequency matched to electron transitions in certain atoms. They are the basis upon which a second is defined. But there is a new kid on the block, the ...

Optical coherence tomography (OCT) is an imaging technology that can non-invasively generate cross-sectional images of tissue. OCT is widely used in eye clinics to diagnose and manage retinal diseases ...
