Experiment suggests quantum computers can coordinate actions of moving devices

New research from the University of Kent has demonstrated that quantum information could eventually be used to coordinate the actions of devices that can move, such as drones or autonomous vehicles. This could lead to more efficient logistics, which could make deliveries cheaper, and better use of limited bandwidth for the likes of self-driving cars. […]

Physicists use sliding seeds to better understand landslides and rock avalanches

Champatis, the seeds of the Lapsi tree, are valued in Nepal for their medical, economic, social, and cultural significance. They are also popular among children as simple playthings. But for a group of physicists, these unique seeds—and the way they bounce and roll down slopes—could help them better understand landslides and avalanches, leading to research […]

Adjusting accelerators with help from machine learning

Banks of computer screens stacked two and three high line the walls. The screens are covered with numbers and graphs that are unintelligible to an untrained eye. But they tell a story to the operators staffing the particle accelerator control room. The numbers describe how the accelerator is speeding up tiny particles to smash into […]

New theory reveals the shape of a single photon

A new theory that explains how light and matter interact at the quantum level has enabled researchers to define for the first time the precise shape of a single photon.

A proposed experiment to test whether gravity behaves as a quantum entity when measured

A multi-institutional team of physicists is proposing an experiment to test whether gravity behaves as a quantum entity when measured. They published a description of their experiment in the journal Physical Review Letters and state that once a means for conducting the experiment has been achieved, they hope the results will lead to the development […]

Quantum computing researchers develop an 8-photon qubit chip

A group of South Korean researchers has successfully developed an integrated quantum circuit chip using photons (light particles). It is a system capable of controlling eight photons using a photonic integrated-circuit chip. With this system, they can explore various quantum phenomena, such as multipartite entanglement resulting from the interaction of the photons.

Scientists discover laser light can cast a shadow

Can light itself cast a shadow? It may sound like a philosophical riddle, but researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow. The discovery challenges the traditional understanding of shadows and opens new possibilities for technologies that could use a laser beam to […]

Physicists identify key mechanism behind chiral charge density wave in TiSe₂

Chirality is a property of some molecules, subatomic particles, living organisms and other physical or biological systems. This property entails a lack of mirror symmetry in these systems’ underlying structures.
