44 km Quantum Teleportation Achieved in USA

Published

A team of scientists from the United States was able to prove the possibility of instantaneous transmission of a quantum state over long distances. The researchers have succeeded in transmitting the quantum state over 44 km with an accuracy of over 90% over fiber optic networks similar to those that form the backbone of the existing Internet.

Instantaneous transmission of a quantum state, or quantum teleportation, is carried out using entangled qubits. By interweaving three qubits, one can force one particle to assume the state of another through their mutually entangled partner. how explains ScienceAlert, it’s like turning one particle into another, teleporting it a distance in the blink of an eye.

The unstable nature of quantum information makes it difficult to transmit entangled qubits over long distances without interference: Long optical fibers mean more noise. In a joint experiment by Fermilab, AT&T, California Institute of Technology, Harvard University, NASA’s Jet Propulsion Laboratory and the University of Calgary, scientists were able to carry out quantum teleportation at a distance of 44 kilometers. Today, this is the limit on how far scientists can send a quantum state.

“We are very proud to have reached this milestone in the development of robust, high-performance and scalable quantum teleportation systems. The results will be further enhanced by system upgrades, which we expect to be completed by the second quarter of 2021. ” told by Maria Spyropoulou, professor of physics at California Institute of Technology.

In future experiments, scientists are going to set a new record for teleportation distance and the number of entangled qubits.

“With this experiment, we are laying the foundation for the construction of an urban quantum network in the Chicago area,” said Panagiotis Spenzuris, Fermilab’s quantum science program manager.

In the summer of 2020, a plan was presented in Chicago to create a quantum Internet in the United States, which should become not only faster, but also safer than the classical one. The Illinois Express Quantum Network is being developed by Fermilab in collaboration with Argonne National Laboratory, California Institute of Technology, Northwestern University and industry partners. For now, researchers believe that quantum internet networks will act as specialized extensions of the classical internet, rather than a complete replacement for it.

Bitcoin soared to the equivalent of 38000 in Nigeria

The price of one bitcoin (BTC) in Nigeria soared to the equivalent of $38,000 in the local currency, naira. This is significantly higher than the price of bitcoin on the world market, which is about $23,000.

At the time of writing, on the Nigerian crypto exchange NairaEX for 1 bitcoin they give 17.4 million naira, which corresponds to 37.8 thousand dollars. The peak value was 38.8 thousand dollars.

This is due to the fact that the Central Bank of Nigeria continues to impose restrictions on cash withdrawals from ATMs in order to reduce the share of cash in money circulation.

Bitcoin soared to the equivalent of $38,000 in Nigeria

In January, new rules were introduced that allowed Nigerians to withdraw no more than 20,000 naira (about $43.50) from ATMs per day, with a weekly limit of 100,000 naira (about $217).

The move was also taken just days before the new naira notes entered circulation in an effort to curb inflation and money laundering. The central bank has set a January 24 deadline for Nigerians to exchange their old higher denomination banknotes for the new currency.

However, long queues and complaints forced the Central Bank to extend Nigeria’s deadline until Feb. 10.

Free and open source graphics editor the mythical GIMP 30

The free GIMP (GNU Image Manipulation Program) raster graphics editor is about to receive a major update. This was reported by the GNU development team in their recent annual report.

Free and open source graphics editor: the mythical GIMP 3.0 will be released before the end of 2023, officially

In November 2022, GIMP celebrated its 27th birthday. Thus, users have been waiting for the third version for a really long time. The possible release of GIMP 3.0 has been talked about for a decade. GIMP 3.0 will have a redesigned user interface, a migration from GTK2 to GTK, and many other changes.

Until the end of 2023, the release of stable versions, or at least the first release candidates, is expected. True, in the report, the developer Jean Pages also left himself room for maneuver:

Here. I said it. If it doesn’t, remember that it wasn’t a promise.

He also explained:

There’s still a lot to be done, so I hope I’m not making a fool of myself. But at some point, the impossibility of the release is simply disappointing. Of course, we’re still within acceptable development time limits (GIMP 2.8-2.10 took 6 years, we’re still in our fifth year after 2.10), but I really want to get it over with.

OnePlus also said that the OnePlus Pad will feature a curved body that is rounded on the sides, allowing users to “comfortably hold the tablet for extended periods of time without fatigue.”

OnePlus hasn’t shared any further details on the tablet’s specs, but it is rumored to have an 11.6-inch display.
