WASHINGTON—The new issue of Optica Quantum is available. A Gold Open Access journal from Optica Publishing Group, Optica Quantum provides a home for ...

Non-Hermitian topological systems exhibit a range of unique phenomena that are absent in their Hermitian counterparts.

An international team of researchers from Vienna University of Technology, Rice University in Texas, the University of ...

Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular ...

Researchers at Tampere University and their collaborators from Germany and India have experimentally confirmed that angular momentum is conserved when ...

To address key challenges for both quantum communication and quantum computing applications in a simultaneous manner, we propose to employ the photon angular momentum approach by invoking the ...

Physicists at the Technion – Israel Institute of Technology say they have observed a new form of quantum entanglement in the total angular momentum of photons confined in nanoscale structures. Their ...

A study from Technion unveils a newly discovered form of quantum entanglement in the total angular momentum of photons confined in nanoscale structures. This discovery could play a key role in the ...

Researchers have experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide. A team of researchers from Würzburg has ...

The breakthrough experiments revealed that the quantum vortex is created by orbital angular momentum – electrons’ circular motion around atomic nuclei. “When we first saw signs that the predicted ...

“This gives us a direct look at a material’s electronic structure in momentum space.” “By cleverly adapting this method, we were able to measure orbital angular momentum.” The team’s work appears in ...
