In a quantum system of arrayed two-level atoms interacting with light, the interacted (dressed) photon is propagating in a periodic medium and its eigenstate ought to be of Bloch type with lattice ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

The 5.4 km free-space quantum communication link between the University of Ottawa and the National Research Council Canada, where real-time atmospheric turbulence measurements were conducted to train ...

Physicists have confirmed the two foundational postulates of Richard Feynman’s path-integral approach to quantum mechanics in ...

Not only do optical fibers transmit infor­ma­tion every day around the world at the speed of light, but they can also be harnessed for the trans­port of quantum infor­ma­tion. In the current issue of ...

Scientists have a history of trying — and failing — to link biology and quantum mechanics. The real connection between them may be in the math.

A new study explores the behavior of photons, the elementary particles of light, as they encounter boundaries where material properties change rapidly over time. This research uncovers remarkable ...

In an exper­i­ment car­ried out in 2009, our group has performed a quantum simu­la­tion of the Dirac equa­tion using a single trapped ion and observed so called Zitter­be­we­gung, a pecu­liar ...

RIT and the University of Rochester will receive $2 million in federal funding to further develop the Rochester Quantum Network (RoQNET). The National Institute of Standards and Technology (NIST) is ...

The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin’s Broome Bridge in 1843. But in his ...

While we're far away from beaming around like 'Star Trek,' innovation of communications technology has become the closest ...

A single-step thermal process reliably generates high-density, narrowband quantum emitters in hexagonal boron nitride. More than 25% of these emitters show room-temperature optical spin readout, ...
