A team of engineers, physicists and quantum specialists at Google Research has found that reducing noise to a certain level allows the company’s sycamore quantum chip to beat classical computers running random circuit sampling (RCS).

The word laser usually conjures up an image of a strongly concentrated and continuous light beam. Lasers that produce such light are, in fact, very common and useful. However, science and industry often also require very short and strong pulses of laser light.

In physics, a system composed of two substances can be modeled in accordance with classical mixture theory, which considers the fraction corresponding to each constituent and the interactions among constituents. Examples include the coexistence of high-and low-density phases in supercooled water, and the coexistence of metal puddles in an insulating matrix in the Mott metal-insulator transition.

Researchers are excited about the potential of microcombs, miniature devices that generate precise time and frequency standards. These microcombs could revolutionize fields from high-speed communication, high-resolution measurements to precise atomic clocks.

Imagine a future where indoor wireless communication systems handle skyrocketing data demands and do so with unmatched reliability and speed. Traditional radio frequency (RF) technologies like Wi-Fi and Bluetooth are beginning to struggle, plagued by limited bandwidth and increasing signal congestion.

UC Santa Barbara researchers have achieved the first-ever “movie” of electric charges traveling across the interface of two different semiconductor materials. Using scanning ultrafast electron (SUEM) techniques developed in the Bolin Liao lab, the research team has directly visualized the fleeting phenomenon for the first time.

First-person drone piloting is yesterday’s news. Drones are becoming smarter as the electronic environment around them makes operator communication more difficult.

Einstein’s strangest theory has been confirmed, as experts have stopped time for the time in history: Find out how they did it.

The solutions to these long-standing problems could further enhance our understanding of symmetries of structures and objects in nature and science, and of long-term behavior of various random processes arising in fields ranging from chemistry and physics to engineering, computer science and economics.

A Rutgers University-New Brunswick professor who has devoted his career to resolving the mysteries of higher mathematics has solved two separate, fundamental problems that have perplexed mathematicians for decades.
