Technology. Teleportation of information in the diamond at the quantum level was made

Nowadays, the biggest problem of the global network are cybercriminals’ attacks. In the future, information transfer over long distances will be carried out in a secure manner in quantum networks.

The great breakthrough in this matter was made by scientists from the Yokohama National University. They were able to teleport quantum information using a diamond. This is a big step towards building the first quantum network, which will enable extremely secure storage and transfer of confidential data.

Quantum teleportation allows the transfer of quantum information to a space that is otherwise unavailable. It also allows the transfer of information to quantum memory without revealing or destroying stored quantum information. This space for scientists has become an inaccessible structure consisting of carbon atoms present in the diamond.

The carbon atom contains six protons and six neutrons, surrounded by six spinning electrons. When atoms combine in a diamond, they automatically create a particularly strong bond. However, errors arise in this process. It comes to them when the nitrogen atom is present in one of the two neighboring free places where the carbon atoms should be.

Scientists define this state as the N-V center. The structure of the nucleus of the nitrogen atom, surrounded by carbon atoms, creates what researchers call nanomagnets. During the experiment, the Japanese attached an extremely thin wire to the surface of the diamond. Using radio and microwave waves, they created an oscillating magnetic field around the diamond. Then they led the spin of electrons to entangle with the atomic spin of carbon, i.e. the angular momentum of the electron and the nucleus of the carbon atom.

Information was teleported in the diamond at the quantum level. Fig. Yokohama National University.

The spin of electrons disintegrated under the influence of the magnetic field created by the nanomagnet, making it prone to entanglement. After entangling the two parts, a photon storing quantum information was introduced and the electron absorbed the photon. Absorption made it possible to transfer the state of photon polarization to carbon, mediated by a tangled electron, demonstrating the teleportation of information at the quantum level. In this way, a fully controlled quantum information transfer environment was created in the heart of the diamond.

“The success of photon storage at the second node establishes entanglement between two neighboring nodes. This process, called the quantum amplifier, can transfer individual pieces of information from a node to a node in the quantum field. Our ultimate goal is the implementation of scalable quantum amplifiers for long-range quantum communication, and distributed quantum computers for quantum computing and metrology on a large scale, “said Hideo Kosaka, author of the study.

RTV Is this what future television looks like? This is the IPTV test

Some time ago, we informed that Cyfrowy Polsat is launching a new interesting service, namely cable television in IPTV technology, thanks to which the reception of TV channels will be possible via the Internet.

This solution went to our editorial office, thanks to which we could test it and now we will share our insights with you. Let’s start with what IPTV television is all about. In short, it is a technology that allows transmission of television signals in IP-based broadband networks. IPTV also allows suppliers to extend the offer with additional functionalities, thanks to which the recipients get very much freedom to watch available content, significantly approaching the classic television model to video on demand services. Is it wrong? Quite the opposite, because as we know well VOD is the future of consuming content, which is well demonstrated by the huge popularity of streaming services.

And how does it look at Cyfrowy Polsat? To receive television in a new form, an EVOBOX IP decoder is needed, and the operator makes it available when buying a selected TV package even from the proverbial zloty. This is a small size (12.2 x 11.5 x 2.8 cm), it is characterized by a quite modern design, and its implementation raises no objections, easily fit into any interior (and takes up very little space). On the back of the decoder we find 5 slots, i.e. optical to transmit digital audio, ETHERNET, HDMI, USB and power, and its installation is trivial and boils down to connecting power and a network cable or wireless connection to our Wi-Fi network. Above all, we do not need any satellite dish, which of course has its advantages, but sometimes its installation is cumbersome or impossible, due to the home infrastructure or location conditions, so IPTV is the perfect solution here.

To use it, we need a fixed internet connection from Plus, Netia or Orange with a minimum download speed of 8 Mb / s for one decoder. Speed ​​should not be a problem, the more so that Plus has just expanded its internet offer with optical fiber. Speeds and fixed line prices start from 150 MB / s and 60 PLN / month, and users get not only a Wi-Fi router (which is of course standard), but also an additional SIM card to use as part of the mobile internet transfer with a 5 GB package month (the package can be enlarged if necessary). The issue of selecting operators is a bit worse, but we hope that it will expand over time.

The decoder is traditionally served by the pilot – a little pity that this is not more modern, but most importantly, that provides access to all the most important options. The closed system software supplied by ADB, which we did not have any problems with during the tests, is responsible for the system’s operation. The whole worked well, allowing, among others for fast channel switching, the use of menus or additional functionalities, and it is very intuitive to use, so anyone can really handle it. As we have already mentioned, we are dealing with TV in IPTV format, so this one offers additional options besides the program offer itself. We are talking about the possibility of creating lists of favorite channels, advanced search and programming, or playing multimedia files from a USB drive and DLNA servers in a local area network (LAN). Noteworthy, however, are 3 functions, thanks to which watching TV starts to resemble video on demand service – I was personally interested in them, because every day I appreciate the comfort of using streaming services, thanks to which I watch what I want and when I want.

The first of these is reStart, which allows you to watch selected programs from linear channels from the beginning, that is, standing in the queue in the store or traffic jam we do not have to worry that we are late for a favorite program, movie or match, because just a few clicks and this it starts again for us. The second option is TimeShift, which allows you to stop and scroll through selected programs for up to 3 hours, in case you want to watch fragments of a show again, because someone has knocked us out with a phone call or knocking on the door. We have the third option, CatchUP, which allows you to watch selected programs up to 7 days back from their broadcast – to put it simply, it is a time-limited VoD service, no additional fees and the need to record, which allows you to additionally select programs from channels linear, not just a specific database of movies and series.

Anyway, if we choose the right package, we will also gain access to the classic HBO GO streaming service, which makes the offer of Cyfrowy Polsat seem even more attractive. In each package, however, there is access to Cyfrowy Polsat GO. I must admit that before the tests I was skeptical about this, but it soon turned out that wrongly – IPTV is a great proposition for all people who on the one hand value the independence of streaming services, on the other have their favorite programs and do not want to give up traditional television. Here we have two in one, i.e. access to linear channels, and selected programs can be viewed at any time – and moreover, also on mobile devices.

For this you can not say a bad word about image quality – especially for channels broadcast in HD. However, we must take into account that the bitrate of channels had to be limited due to the low internet connection requirements, thanks to which the provider can reach a much larger audience. However, this does not prevent the transmission of a signal of a suitable quality also in the case of more dynamic transmissions, especially live, see sport. However, one can not forget about the dependence of IPTV on the Internet – just a break in the operation of the network and television can not be watched. It should also be noted that in terms of sound we can choose between stereo and Dolby Digital Plus surround sound.

Bandwidth used:

for SD channels:

•720×[email protected] bitrate 780 kbps

•960×[email protected] bitrate 1,618Mbps

for HD channels:

•960×[email protected] bitrate 1,618 Mbps

•1280×[email protected] bitrate 2,8 Mbps

•1920×[email protected] bitrate 5,0 Mbps

for Super HD channels:

•960×[email protected] bitrate 1,618 Mbps

•1280×[email protected] bitrate 2,8 Mbps

•1920×[email protected] bitrate 8,0 Mbps

IPTV cable television is a very good solution for many households, especially that Cyfrowy Polsat makes it available in almost the same packages as its satellite services, so everyone will find the right option. The offer with 70 channels, including Cinemax cinemas, costs PLN 20 per month, but we can also choose a package with an additional 3 Eleven Sports channels for PLN 30 / month. or richer with 138 channels for PLN 60 / month. The most awesome option with the full offer and premium channels, i.e. 152 channels (of which over 90 in HD quality) from HBO, Eleven Sports and Polsat Sport Premium, costs PLN 120 / month. By the way, it is worth mentioning that Cyfrowy Polsat gives the possibility to combine IPTV with other services of its and the Plus network (also with fiber optic Internet) as part of the smartDOM program. What’s more, we can check the new service completely for free for 14 days as part of the “TV for a try” promotion in the stationary sales outlets, and it is important that later we have to decide to sign a 2-year contract.

In conclusion, IPTV cable TV is an innovative and very interesting solution. People who for various reasons, such as home infrastructure or location conditions, will certainly appreciate them – we can forget about the need to install a plate, and the connection of an IPTV decoder is very easy. The whole works very well, the channels switch quickly, the HD picture quality is satisfying, and additional decoder functions, such as reStart, TimeShift or CatchUP, make us watch TV on our own terms, with a great deal of freedom to choose the time and programs that interest us. 14 days for free testing of the service is a sufficient time for everyone to see if it’s the solution for him.

Automotive This is Lightyear One, an electric solar car with a record range

Electric vehicles are the future of motoring. Unfortunately, the shortest range is still their biggest nightmare. This fact discourages many potential customers, but soon this fact can go down in history thanks to Lightyear.

The Dutch startup designed from scratch and built an amazing car that can change the world of electric vehicles. The engineers were based on the experience of the famous solar vehicle racing iLumen European Solar Challenge and the Bridgestone World Solar Challenge. His domain is not only an interesting appearance and a comfortable interior, but above all a large range. A vehicle called Lightyear One can be not only loaded in the traditional way from the outlet, but also powered by the sun’s energy. It is this fact that gives him a huge advantage over the competition.

Lightyear One can easily beat up to 725 kilometers (WLTP). This is a great result, eg compared to municipal electricians offered by German, French and Japanese concerns, and even better than Tesla vehicles. The engineers managed to do this by equipping the vehicle with very efficient solar panels. They are located on the Lightyear One mask, roof, rear window and trunk.

Photovoltaic panels with an area of ​​5 square meters get solar energy and recharge batteries on board. The energy can also be supplemented in the traditional way, that is, connecting the vehicle to the sockets on the charging stations. The fast system can charge up to 507 kilometers in an hour. On a sunny day, the panels are able to provide energy to batteries for up to 12 kilometers in one hour.

This means that during our 6-8-hour stay at work or at the university, Lightyear One can win so much energy that it can offer us nearly 100 km of coverage. We can get back home for free, and we can still jump out of town. The company’s representatives boast that during the year, thanks to solar panels, the vehicle will drive itself up to 20,000 kilometers.

“This moment presents a new era of driving. Two years of dreams, thinking and hard work have led to a new milestone, which is a huge step towards achieving our mission’s goal and ensuring ecological mobility for everyone, “said Lexighear Lex Hoefsloot, Lightyear’s CEO. The company has already made it possible to place orders for this unique vehicle. Its price is to amount to 170 thousand dollars, and deliveries are to start in early 2021.

Huawei does not want to give up Android, but he also has other ideas

huawei google android 2019

Huawei constantly signals readiness to cooperate with American companies, at the same time develops its own solutions. It all fits into difficult American-Chinese trade talks

One thing is for sure. The current users of Huawei smartphones, computers and tablets – and the Honor brand belonging to it – can sleep peacefully. The Chinese corporation, the second largest manufacturer of smartphones in the world after Samsung and the largest global provider of telecommunications solutions, consistently ensures that the Donald Trump administration introduced in May prohibits cooperation of American companies with it, does not cut its users from applications created in the US, Android system and upgrades to them.

Still applications for use of YouTube, Gmail or Google Maps will work and will be updated, Android will install further security and Huawei’s equipment will continue to operate abroad – even in the United States. And, very importantly, this applies to both Huawei devices that have already been sold and those that are now waiting for sales in stores and warehouses.

Huawei’s approach is also confirmed by the reactions of its key US partners. – We follow the ordinance and analyze the implications. For users of our services, Google Play and Google Play Protect, they will continue to work on existing Huawei devices, say Google.

New operating system in preparation
The Chinese company still wants to cooperate with American companies, including Google, a key player in the context of the mobile market and the creator of Android. – Android is an “open source” platform and Huawei has significantly contributed to its development and popularization around the world. Huawei will continue to prioritize the development and use of the Android ecosystem, we read in the group’s statement.

But the company does not want to solely base its development on the assumption that it will be possible to quickly abolish the ban on cooperation with US companies. He also looks for alternative solutions.

One of them is going to be a new operating system, which the company has been working on since 2012. His name is Hongmeng

and Huawei began registering his trademark in Europe and outside of China about a month ago – relevant applications were received, inter alia, by the patent offices of the European Union, Canada, Australia, South Korea, Mexico and Peru. In China, this step was taken already last year.

Hongmeng – just like Android – is to be multi-platform, and so operate on smartphones, tablets, laptops and smartwatches. It also has to allow you to run Android applications.

These steps are also correlated with the information provided by the XDA Developers website providing information on everything important in the global software industry. In his opinion, Huawei is just encouraging developers to publish applications in its virtual AppGallery store. In the e-mail he sent to them, the company reminds that over the past two years, it has sold over 350 million devices, of which roughly half went to the western markets. All of these devices have a pre-installed AppGallery application, so the potential circle of recipients of the programs provided by it is very large. Huawei announces that it is ready to help with free access to its applications in AppGallery, as well as in their advertising in the store.

Negotiations are underway
Perhaps, however, Huawei will regain in a very long time the opportunity to cooperate with American companies. The sanctions that fell on him from the White House must be viewed in the wider context of the ongoing US-China trade conflict.

One of his last accents was the decision of Donald Trump from May 10 to impose a 25-percent. duty on Chinese goods worth $ 200 billion. and Beijing’s response to this move, or an increase in tariffs on US goods sent to China worth $ 60 billion. The Middle Kingdom clearly indicates that for him, entering Huawei blacklist of the US Department of Commerce a moment later is a hostile act that is part of the trade conflict.

And that’s why perhaps the abolition of sanctions on Huawei will be part of a wider US-Chinese agreement. We do not have to wait for a while, however. For now, the negotiations have stalled, although the chief economic advisor of the White House, Larry Kudlow, said that before their interruption in May, 90 percent had already been agreed. future layout. Maybe the talks will start at the end of June, if in Japan at the G20 summit Trump meets with Xi.

The chances that the Americans finally get along with the Chinese are big. The prolonged trade conflict is not on hand. Suffering not only Huawei.
