Physicists successfully carry out controlled transport of stored light — ScienceDaily

A team of physicists led by Professor Patrick Windpassinger at Johannes Gutenberg University Mainz (JGU) has successfully transported light stored in a quantum memory over a distance of 1.2 millimeters. They have demonstrated that the controlled transport process and its dynamics has only little impact on the properties of the stored light. The researchers used ultra-cold rubidium-87 atoms as a storage medium for the light as to achieve a high level of storage efficiency and a long lifetime.

“We stored the light by putting it in a suitcase so to speak, only that in our case the suitcase was made of a cloud of cold atoms. We moved this suitcase over a short distance and then took the light out again. This is very interesting not only for physics in general, but also for quantum communication, because light is not very easy to ‘capture’, and if you want to transport

Technological innovation and process optimization are booming. Changes and restrictions in physical interaction since the pandemic have forced companies to change the way they operate and do business, the recent McKinsey & Company survey “What 800 executives envision for the postpandemic workface ” conducted of executives of companies around the world, shows that a third of companies have accelerated the digitization of their supply chains, half have accelerated the digitization of their customer service channels, and two-thirds have more quickly adopted artificial intelligence and automation.

Undoubtedly, the pandemic has shown us that the digitization of companies of any size is necessary and that being prepared and being able to adapt quickly is essential. There has been an important

Flood barrier successfully protects Venice from high tide

VENICE, Italy (Reuters) – A long-delayed flood barrier system successfully protected Venice from a high tide for the first time on Saturday, bringing big relief to the lagoon city after years of repeated inundations.

“Today, everything is dry,” mayor Luigi Brugnaro said on Twitter. “Pride and joy.”

The network of 78 bright yellow barriers that guard the entrance to the delicate Venetian lagoon lifted from the sea bed as the tide, driven by strong winds and rain, started to climb.

City officials had forecast a tide of 130 cm (4.27 ft), well below the devastating the 187 cm tide that battered Venice last November, but enough to leave low-lying areas deep under water.

Powered by Jabil Photonics’ GA CFP2 Digital Coherent Optics (DCO) 100G/200G module, the first network scenario showcased an unamplified metro Wavelength-Division Multiplexing (WDM) point-to-point link with 8 channels at 100Gb/s rate with the module achieving a 32dB error-free link (approximately 130Km single mode fiber) using the 100G Quadrature Phase Shift Keying (QPSK) with Soft-Decision Forward Error Correction (SD-FEC) mode enablement.

The second network scenario for the same CFP2 DCO module involved a single channel 100Gb/s application reaching a 38dB 100G error-free link (more than 150Km

ISS successfully dodges ‘unknown piece of space debris’

The ISS has to watch out for space junk.


NASA

With space junk piling up around our planet, the International Space Station needed to perform a last-minute avoidance maneuver Tuesday to steer clear of an “unknown piece of space debris expected to pass within several kilometers.”

Mission Control in Houston conducted the move at 2:19 p.m. PT using the Russian Progress resupply spacecraft docked to the ISS to help nudge the station out of harm’s way. 

“Out of an abundance of caution, the Expedition 63 crew will relocate to their Soyuz spacecraft until the debris has passed by the station,” NASA said in a statement prior to the move. 

The maneuver went off smoothly, NASA administrator Jim Bridenstine reported. “The astronauts are coming out of safe haven,” he tweeted after the ISS relocated.
