'Quantum optical antennas' provide more powerful measurements on the atomic level

Similar to how a radio antenna plucks a broadcast from the air and concentrates the energy into a song, individual atoms can collect and concentrate the energy of light into a strong, localized signal that researchers can ...

Mapping noise to improve quantum measurements

One of the biggest challenges in quantum technology and quantum sensing is "noise"–seemingly random environmental disturbances that can disrupt the delicate quantum states of qubits, the fundamental units of quantum information.

Highly sensitive diamond quantum magnetometer can achieve practical ambient condition magnetoencephalography

A highly sensitive diamond quantum magnetometer utilizing nitrogen-vacancy centers can achieve millimeter-scale resolution magnetoencephalography (MEG), as reported by scientists from Tokyo Tech. The novel magnetometer, based ...

Opinion: Africa doesn't have choice between economic growth and protecting the environment—how they can merge

Heathrow Airport in the UK currently uses more energy than the entire west African country of Sierra Leone. Despite Africa accounting for less than 4% of all global greenhouse gas emissions, many of its countries face significant ...

Scientists bring crystal clarity to diamond's quantum signals

They say that one can miss the forest for the trees. But it's often worth taking a closer look at the trees to make sense of the dense, brambly whole. That's what a Stanford University group did to tackle a thorny quantum-information ...

Scientists develop 'X-ray vision' technique to see inside crystals

A team of New York University researchers has created a new way to visualize crystals by peering inside their structures, akin to having X-ray vision. Their new technique—which they aptly named "Crystal Clear"—combines ...

Research team demonstrates modular, scalable hardware architecture for a quantum computer

Quantum computers hold the promise of being able to quickly solve extremely complex problems that might take the world's most powerful supercomputer decades to crack.

Biodiversity in the margins: Merging farmlands affects natural pest control

A new study published in the Journal of Applied Ecology demonstrates how the diversity and abundance of arthropods decrease when hedgerows and field margins covered by wild grass and flowers are removed.

Record low Antarctic sea ice 'extremely unlikely' without climate change, says scientists

Scientists at the British Antarctic Survey (BAS) have found that the record-low levels of sea ice around Antarctica in 2023 were extremely unlikely to happen without the influence of climate change. This low was a one-in-a-2000-year ...

Using DNA origami, researchers create diamond lattice for future semiconductors of visible light

The shimmering of butterfly wings in bright colors does not emerge from pigments. Rather, photonic crystals are responsible for the play of colors. Their periodic nanostructure allows light at certain wavelengths to pass ...
