Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical ...

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, ...

Low-power optical device achieves around 100 times amplification using just a couple of hundred milliwatts of input power ...

Researchers from the University of Science and Technology of China have achieved a major breakthrough in optical clock technology, developing a strontium optical lattice clock with stability and ...

A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

A new generation of specialty optical fibers has been developed by physicists to cope with the challenges of data transfer expected to arise in the future age of quantum computing. A new generation of ...

Biological physics, or the physics of living systems, has emerged fully as a field of physics, alongside more traditional fields of astrophysics and cosmology, atomic, molecular and optical physics, ...

Atomic, molecular, and optical (AMO) physics is a foundational discipline within the physical sciences. It is the study of light and matter and their interactions, and deals with electrons, atoms, ...

In the age of information, data processing and computation are essential. But current computation devices lack scalability and suffer from high carbon emissions. So researchers are constantly looking ...

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 ...

Given their tiny size, individual atoms are notoriously tricky to see and manipulate, but finding ways to do so would be extremely useful. The invention of the laser in the 1960s eventually led to the ...
