Germans created a quantum logic gate between two qubits in two different laboratories

German researchers at the Max Planck Institute for Quantum optics have a logical Gate operation performed with two qubits located in two different laboratories. Your achievement is a very important step towards distributed quantum processing. It could allow the building of modular computer systems made up of devices that are in different places but function like one big computer. The addition of another qubits now quantum computers is not an easy task. Qubits must be able to perform logical operations and at the same time from external influences (noise) that their Quantum state can destroy, be isolated.
A very important source of noise in Quantum systems is the interference between the qubits themselves. For example, if we have a system of 4 qubits and we want to perform calculations involving only 2 of them, there is still a risk of interaction between qubitswho do not participate in the calculations.

Super fast ion tunnel

We live in a modern world full of devices that run on electricity. The development of new technologies ensures that cell phones, laptops, tablets and many other mobile devices are with us every step of the way. Lithium-ion batteries, so-called Li-ion rechargeable batteries, are most commonly used for powering mobile devices, but due to their slow charging, short service life and environmental pollution (due to the high content of heavy metals, e.g. cobalt), more and more attention is being paid to Super capacitors directed. These are devices that have properties of Batteries and capacitors combine. What is it related to? Longer service life, easier recycling and, above all, faster charging, which means time savings. After all, time is money.

Light levitation

Researchers at the University of Pennsylvania have succeeded in floating two small plastic plates with ordinary light. Using the energy from bright LEDs placed in a vacuum chamber, the researchers brought the two Miniature Mylar Sheets to float. This was seen as a breakthrough as it had never been possible to lift such large objects with light alone.


The kind of Polyesterfrom which the light Levitation plates is under the trade name Mylar known. The underside was covered with a special layer that, when heated by the light rays of the LEDs, gave off energy to the air molecules below, causing the plate to float. The achievement was described in the journal Science Advances.

Another idea for studying gravitational waves. Probes flying to Uranus and Neptune could be used

According to research by a Swiss-Danish team of scientists, vehicles that will be sent to Uranus and Neptune in the next decade could be used to study Gravitational waves can be used. According to the scientists, the analysis of radio signals sent to Earth by vehicles in the outer regions of the solar system will make it possible to Space-time disturbances to analyze caused by gravitational waves.

Scientists have managed to find out some properties of Einsteinium

The Lawrence Berkeley National Laboratory (LBNL) succeeded in making the first measurements of the atomic bond length of einsteinium perform. This is one of the fundamental properties of the interaction of the element with other atoms and molecules. Even though einsteinium Discovered 70 years ago, not much is known about it. This is because the element is very difficult to obtain and highly radioactive.

einsteinium was discovered in 1952 by Albert Ghiorso in the remains of a thermonuclear bomb explosion. During the explosion, the nucleus of 238U captures 15 neutrons and 253U is created, which becomes 7E after the emission of 253 electrons.
The scientific team, led by Professor Rebecca Abergel from the LBNL and Stosh Kozimor from Los Alamos National Laboratory, had less than 250 nanograms of the element available.

New plasma drive lets you travel to the outer planets of the solar system?

Fatima Ebrahimi, Princeton physicist Plasma Physics Laboratory (PPPL), is the author of a new rocket propulsion concept that would enable astronauts to reach the outer planets of the solar system. Her idea is to use a magnetic field to accelerate plasma particles and use them to propel a spacecraft.

“The idea came to me in 2017 while I was sitting at my desk and pondering the similarities between the gases coming out of a car's exhaust and the fast-moving particles produced by the National Spherical Torus Experiment (NSTX). This generates during operation tokamak magnetic bubbles, so-called Plasmoidmoving at about 20 km / s. To me it looked like a jet, ”says the scientist.

The Earth's magnetosphere could encourage the formation of water on the lunar surface

Before the era of the Apollo expeditions, researchers believed that the moon was an arid desert. All because of the extreme temperatures on its surface and the harsh space environment. However, much has changed since then, and scientists have confirmed the existence of water on the moon (NASA confirms the presence of water in the sunny regions of the moon). It is found in the form of ice in the shady polar craters, it is bound in sediments in the lunar soil and in rocks of volcanic origin. However, there is still uncertainty about the amount and origin of the water on the moon.

As if there was no atmosphere. New technology will make it possible to check Albert Einstein and communicate with satellites

Scientists from the International Center for Radio Astronomy Research (ICRAR) and from the University of Western Australia (UWA) have worked with specialists in the French National Center for Space Research (CNES) and the Systèmes de Référence Temps-Espace laboratory at the Paris observatory set a world record for the most stable transmission of laser light through the atmosphere.
They used innovative Australian solutions to Phase stabilization in combination with advanced optical terminals. This sent laser lightthat is not disturbed by the presence of the atmosphere. "We are able to correct turbulence in 3D, that is left-right, up-down and above all along the beam path.

How big can black holes be? Scientists suspect the existence of galaxy-sized black holes

The most massive are observed in the centers of large galaxies. They reach masses tens of billions of the mass of our sun. But a new study suggests that much larger black holes could exist, and in the new study, researchers at Queen Mary University London wanted to better understand black holes and limit how big they could be. In the work that appeared in the journal Monthly Notices of the Royal Astronomical Society, scientists proposed a new class of black holes - stupendously large black holes (SLABs).

SLAB

The researchers initially indicated that there was no evidence for the existence of black holes more massive than those we observe in the centers of the most massive galaxies. - We already know that black holes exist over a wide range of masses, with a supermassive black hole of four million solar masses in the center of our galaxy, "explains astronomer Bernard Carr of Queen Mary University London - although there is currently none With evidence for the existence of SLABs, it is conceivable that they could exist and be outside of galaxies, in intergalactic space, which has interesting implications for observation, he added.
