Secure quantum communications in the microwave range for the first time

Posted by in categories: computing, particle physics, quantum physics

Mikel Sanz, of the Physical Chemistry Department of UPV/EHU, leads the theoretical group for an experiment published by the prestigious journal, Nature Communications. The experiment has managed to prepare a remote quantum state; i.e., absolutely secure communication was established with another, physically separated quantum computer for the first time in the microwave regime. This new technology may bring about a revolution in the next few years.

Within the greater European project of the Quantum Flagship, spearheaded by Mikel Sanz—researcher of the QUTIS Group of the UPV/EHU Physical Chemistry Department—an experiment has been conducted in collaboration with German and Japanese researchers who have managed to develop a protocol for preparing a remote quantum state while conducting in the regime, “which is the frequency at which all quantum computers operate. This is the first time the possibility of doing so in this range has been examined, which may bring about a revolution in the next few years in the field of secure quantum communication and quantum microwave radars,” lead researcher in this project Mikel Sanz observes.

The preparation of a remote quantum state (known as remote state preparation) is based on the phenomenon of quantum entanglement, where sets of entangled particles lose their individuality and behave as single entities, even when spatially separated. “Thus, if two computers share this quantum correlation, performing operations on only one of them can affect the other. Absolutely secure communication can be achieved,” Sanz explains.

A Japanese spacecraft just grabbed more rocks from the asteroid Ryugu

Posted by in categories: materials, space

Japanese spacecraft landed on the asteroid surface.


Hayabusa2 has collected a second sample from the asteroid’s surface. It could give us a unique insight into how the early solar system was formed.

The procedure: After a few hours of maneuvering, the spacecraft touched down on Ryugu’s surface at 9:15 p.m. US Eastern time yesterday. It then fired a bullet into the asteroid and collected some of the debris stirred up by the shot. The Japanese space agency JAXA tweeted that the mission had been a success and that the space probe had now left the surface again. It’s the second sampling mission after a similar one in April, and it required particularly careful preparations, because any problems could cause the materials gathered during the first operation to be lost. In April, Hayabusa2 had also fired a copper bomb into the asteroid’s surface to expose the rocks beneath, in anticipation of today’s mission.

Naruto running?


A Facebook event called “Storm Area 51, They Can’t Stop All of Us” has amassed an army of memers, schemers and tinfoil hat-wearing conspirators to raid the top-secret Air Force military base in the middle of Nevada’s desert.

Over 289,000 users confirmed they’re planning to come along, while 314,000 are “interested.” It’s gotten so big that the event is grabbing the attention of local and even international media.

A 550 km-long mass of sargassum seaweed is heading for the pristine beaches of Mexico’s Yucatan Peninsula

Posted by in category: economics

But now much of the coast is covered in heaps of rotting seaweed, contributing to an economic and ecological crisis.

The issue has been caused by an enormous bloom of sargassum algae, which washed ashore from the nearby Sargasso Sea. There has long been sargassum in that part of the ocean. But the rate of its growth has increased rapidly in recent years – so much so that in 2018 its summer bloom almost spanned the Atlantic from West Africa to the Caribbean.

And things are set to get even worse.

Massive reforestation is key to averting a climate catastrophe

The study also suggests that reforesting such a large area wouldn’t impact our capacity for growing and farming food.
