It's been 37 years since scientists first demonstrated the ability to move single atoms, suggesting the possibility of designing materials atom by atom to customize their properties. Today there are ...

A project at Macquarie University has demonstrated a way to narrow the linewidth of a laser beam by a factor of over ten thousand. Published in APL Photonics, the technique offers a promising route ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

In the quest for ultra-secure, long-range quantum communication, two major challenges stand in the way: the unpredictable nature of atmospheric turbulence and the limitations of current optical ...

Quantum physics describes matter and light in terms of discrete quanta and inherently probabilistic rules that depart from classical intuition. At its heart lie wave–particle duality—entities such as ...

In typical applications of PTTI, entire systems consisting of the high-performance clocks, local oscillators, and distribution systems provide the needed signal. For this reason, advancing the ...
