The team of Li Chengfeng, Zhou Zongquan and others from the CAS Key Lab of Quantum Information developed a multi-degree-of-freedom (DOF) multiplexed solid-state quantum memory, and demonstrated photon pulse operation functions with time and frequency DOFs. The results were published in Nature Communications recently.

The reliable storage and coherent manipulation of quantum states with matter-systems enable the construction of large-scale quantum networks based on a quantum repeater. To achieve useful communication rates, highly multi-mode quantum memories will be required to construct a multiplexed quantum repeater.

The team presented the first demonstration of the on-demand storage of orbital-angular-momentum states with weak coherent pulses at the single-photon-level in a rare-earth-ion doped crystal. Through the combination of this 3-dimensional spatial DOF with 2-dimensional temporal and 2-dimensional spectral DOFs, the team created a multiple-DOF memory with high multi-mode capacity up to 3×2×2=12.

Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, rage against the dying of the light. – Dylan Thomas.

The country isn’t a world leader in autonomous or electric vehicles, but it’s all in on putting cars in the sky.

The news: Japan announced today that it’s bringing together 21 companies and organizations, including big hitters like Uber, Boeing, Airbus, Cartivator, and Japan Airlines, to bring aerial vehicles to the skies within 10 years.

The challenge: The government said it will address one of the major things holding back flying cars: regulation. “The Japanese government will provide appropriate support to help realize the concept of flying cars, such as creation of acceptable rules,” the ministry said. If Japan is able to quickly establish a legal system in which flying cars can function, it could get a jump start over countries like the US, whose Federal Aviation Association has been notoriously slow-moving on things like drone regulation.

T-Mobile disclosed an “incident” in which hackers accessed “some” customers’ personal information—but no financial data or passwords.

The facial recognition technology the US is testing for airports has caught its first imposter merely three days after Washington Dulles International started using it. According to US Customs and Border Protection (CBP), a 26-year-old man from Sao Paulo, Brazil successfully fooled people with a French passport until he presented it to a Dulles officer who used the new facial comparison biometric technology. The system determined that his face wasn’t a match with the person in the passport, and he was sent for a comprehensive check, which revealed the Republic of Congo ID hidden inside his shoe.

AI, and more specifically machine learning, deep learning and neural machine technology, will soon take over jobs which are currently performed by experienced and well-educated humans. Here we take a look at translators and how their job will be augmented and automated by intelligent machines.

Graphene is famous as a two-dimensional material, but to really make the most of the stuff we need to coax it back into 3D forms. Now researchers from Virginia Tech have developed a new way to 3D print graphene aerogels with a far higher resolution than previously possible.

The hydrogen economy has been touted for decades as a way to navigate the clean energy transition. Now a new CSIRO roadmap sets out how hydrogen power can become a major energy player.

Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week’s contribution is from Michael Poland, geophysicist with the U.S. Geological Survey and Scientist-in-Charge of the Yellowstone Volcano Observatory.

Norris Geyser Basin is one of the most dynamic geyser basins in Yellowstone National Park. It frequently experiences “disturbances” when thermal activity waxes and wanes and water chemistry changes over the course of a season.

Earthquake swarms are common nearby, and the surface moves up and down with some regularity. This dynamic behavior was emphasized by the 2003 disturbance, which was associated with an increase in ground and water temperatures, the formation of new springs, mudpots, and geysers, an uptick in overall geyser activity, and an expansion of areas of heated ground.
