Stretched Photons Recover Lost Interference

The smallest pieces of nature—individual particles like electrons, for instance—are pretty much interchangeable. An electron is an electron is an electron, regardless of whether it’s stuck in a lab on Earth, bound to an atom in some chalky moon dust or shot out of an extragalactic black hole in a superheated jet. In practice, though, differences in energy, motion or location can make it easy to tell two electrons apart.

Quantum Materials Symposium to Showcase Local Expertise and Highlight Partnerships in D.C. Region

The University of Maryland will hold a one-day symposium focusing on local research into quantum materials—condensed matter systems that exhibit strong quantum effects and hold promise as potential components in next-generation computers, sensors and other devices. The symposium will be held Sept. 26, 2019, on campus in the Kim Engineering Building.

Hosted by UMD’s Center for Nanophysics and Advanced ...

Taming chaos with physics and AI

In many situations, chaos makes it nearly impossible to predict what will happen next. Nowhere is this more apparent than in weather forecasts, which are notorious for their unreliability. But the clever application of artificial intelligence can help reign in some chaotic systems, making them more predictable than ever before.

In this episode of Relatively Certain, Dina sits down with ...

Ions clear another hurdle toward scaled-up quantum computing

Scientists at the Joint Quantum Institute (JQI) have been steadily improving the performance of ion trap systems, a leading platform for future quantum computers. Now, a team of researchers led by JQI Fellows Norbert Linke and Christopher Monroe has performed a key experiment on five ion-based quantum bits, or qubits. They used laser pulses to simultaneously create quantum connections between ...

Corkscrew photons may leave behind a spontaneous twist

Everything radiates. Whether it's a car door, a pair of shoes or the cover of a book, anything hotter than absolute zero (i.e., pretty much everything) is constantly shedding radiation in the form of photons, the quantum particles of light.

A twin process—absorption—is usually also present. As photons carry away energy, passers-by from the environment can be absorbed to replenish ...

Perfect quantum portal emerges at exotic interface

Researchers at the University of Maryland have captured the most direct evidence to date of a quantum quirk that allows particles to tunnel through a barrier like it’s not even there. The result, featured on the cover of the June 20, 2019 issue of the journal Nature, may enable engineers to design more uniform components for future quantum computers, ...

Ring resonators corner light

Researchers at the Joint Quantum Institute (JQI) have created the first silicon chip that can reliably constrain light to its four corners. The effect, which arises from interfering optical pathways, isn't altered by small defects during fabrication and could eventually enable the creation of robust sources of quantum light.

That robustness is due to topological physics, which describes the properties ...
