Researchers at Penn Engineering have created a chip that outstrips the security and robustness of existing quantum communications hardware. Their technology communicates in "qudits," doubling the quantum information space ...
Multimode optical fibers (MMFs) are hair-thin strands of glass that are ubiquitous in light-guiding applications. Their development has gone hand-in-hand with the huge growth in rapid transmission of information across the ...
A team of researchers at the MPQ has pioneered the integration of erbium atoms with special optical properties into a silicon crystal. The atoms can thus be connected by light at a wavelength that is commonly used in telecommunications. ...
Canada is a world leader in developing quantum technologies and is well-positioned to secure its place in the emerging quantum industry.
Physicists Alain Aspect, John Clauser and Anton Zeilinger developed experimental tools that helped prove quantum entanglement—a phenomenon Albert Einstein famously dismissed as "spooky action at a distance"—is real, paving ...
At the nanoscale, the laws of classical physics suddenly become inadequate to explain the behavior of matter. It is precisely at this juncture that quantum theory comes into play, effectively describing the physical phenomena ...
Mathematicians often toil in obscurity, and that's likely because few people, apart from fellow mathematicians who share the same sub-specialty, understand what they do. Even when algorithms have practical applications, like ...
In the 1930's when scientists, including Albert Einstein and Erwin Schrödinger, first discovered the phenomenon of entanglement, they were perplexed. Entanglement, disturbingly, required two separated particles to remain ...
For the first time, scientists at the University of Oxford have been able to demonstrate a network of two entangled optical atomic clocks and show how the entanglement between the remote clocks can be used to improve their ...
Researchers from Skoltech, the University of Iceland, and the University of Southampton have demonstrated the formation of an odd never-before-seen entity from the realm of quantum physics: a cluster of optical vortices with ...
