Manufacturing-friendly SiC boasts quantum credentials at telecom wavelengths

Decoherence is the bane of quantum technologies. In coherent systems, the phase of the wave functions representing the quantum states of particles in the system have definite relations between each other. This allows quantum devices to operate in a meaningful way that differs from classical devices. However, interacting with the world around us rapidly leads to decoherence, which makes it harder to exploit quantum effects for enhancing computation efficiency or communication security. Research has shown that quantum systems with impressively long coherence times are possible in diamond, but diamond is far from the favorite for manufacturers. Now, researchers at the University of Science and Technology in Hefei and Wuhan University in China have demonstrated SiC can boast some of the quantum merits of diamond with the additional advantage of optical control at the wavelengths used by the telecommunications industry.

Shedding new light on nanolasers using 2-D semiconductors

In his latest line of research, Cun-Zheng Ning, a professor of electrical engineering in the Ira A. Fulton Schools of Engineering at Arizona State University, and his peers explored the intricate balance of physics that governs how electrons, holes, excitons and trions coexist and mutually convert into each other to produce optical gain. Their results, led by Tsinghua University Associate Professor Hao Sun, were recently published in the Nature publication Light: Science & Applications.

Astronomy and Space news

Astronomers probe the emission from a nearby pulsar wind nebula

Astronomers from South Korea and China have performed a deep X-ray spectral imaging of a bow-shock pulsar wind nebula (PWN) associated with a nearby pulsar designated PSR B1929+10. The new study, published April 29 on arXiv.org, presents the deepest investigation of the system, disclosing important information about the emission from this PWN.

China plans to complete space station by 2022

China plans to send four crewed space missions and the same number of cargo craft to complete work on its permanent space station within about two years, officials said after the launch of a newly designed spacecraft aboard the latest heavy-lift rocket.

Astronomers find closest black hole to Earth

A team of astronomers from the European Southern Observatory (ESO) and other institutes has discovered a black hole lying just 1000 light-years from Earth. The black hole is closer to our Solar System than any other found to date and forms part of a triple system that can be seen with the naked eye. The team found evidence for the invisible object by tracking its two companion stars using the MPG/ESO 2.2-metre telescope at ESO's La Silla Observatory in Chile. They say this system could just be the tip of the iceberg, as many more similar black holes could be found in the future.

The Sun is less active magnetically than other stars

Our sun is the source of life on Earth. Its calm glow across billions of years has allowed life to evolve and flourish. This does not mean the sun doesn't have an active side. We have observed massive solar flares, such as the 1859 Carrington event, which produced northern lights as far south as the Caribbean, and drove electrical currents in telegraph lines. If such a flare occurred in Earth's direction today, it would devastate our electrical infrastructure. But fortunately for us, the sun is mostly calm—unusually calm when compared to other stars.

Perseverance Mars rover scientists train in the Nevada desert

Technology news

A technique to produce patterned transition metal ditelluride layers for 2-D devices

Researchers at Ulsan National Institute of Science and Technology (UNIST) in South Korea have recently introduced a method to produce thin and patterned transition metal ditelluride films to be integrated in 2-D metal semiconductors. Their synthesis technique, presented in a paper published in Nature Electronics, could mitigate the challenges associated with the high contact resistance of existing electronics based on 2-D materials.
