To Know More about Quantum Computer, Read the Given Below Article.
For most of our history, human technology consisted of our brains, fire, and sharp sticks. While fire and sharp sticks became power plants and nuclear weapons, the biggest upgrade has happened to our brains. Since the 1960’s, the power of our brain machines has kept growing exponentially, allowing computers to get smaller and more powerful at the same time. But this process is about to meet its physical limits.
Computer parts are approaching the size of an atom. To understand why this is a problem, we have to clear up some basics.
A computer is made up of very simple components doing very simple things.
Representing data, the means of processing it, and control mechanisms. Computer chips contain modules, which contain logic gates, which contain transistors.
A transistor is the simplest form of a data processor in computers, basically, a switch that can either block or open the way for information coming through. This information is made up of bits which can be set to either 0 or 1. Combinations of several bits are used to represent more complex information. Transistors are combined to create logic gates which still do very simple stuff.
For example, an AND Gate sends an output of 1 if all of its inputs are 1, and an output of 0 otherwise. Combinations of logic gates finally form meaningful modules, say, for adding two numbers. Once you can add, you can also multiply, and once you can multiply, you can basically do anything. Since all basic operations are literally simpler than first-grade math, you can imagine a computer as a group of 7-year-olds answering really basic math questions.
A large enough bunch of them could compute anything from astrophysics to Zelda. However, with parts getting tinier and tinier, quantum physics are making things tricky. In a nutshell, a transistor is just an electric switch. Electricity is electrons moving from one place to another. So, a switch is a passage that can block electrons from moving in one direction.
Today, a typical scale for transistors is 14 nanometers, which is about 8 times less than the HIV virus’ diameter, and 500 times smaller than a red blood cell. As transistors are shrinking to the size of only a few atoms, electrons may just transfer themselves to the other side of a blocked passage via a process called Quantum Tunneling.
In the quantum realm, physics works quite differently from the predictable ways we’re used to,
and traditional computers just stop making sense. We are approaching a real physical barrier to our technological progress. To solve this problem, scientists are trying to use these unusual quantum properties to their advantage by building quantum computers. In normal computers, bits are the smallest unit of information.
Quantum computers use qubits which can also be set to one of two values. A qubit can be any two-level quantum system, such as a spin and a magnetic field, or a single photon. 0 and 1 are this system’s possible states, like the photons horizontal or vertical polarization. In the quantum world, the qubit doesn’t have to be just one of those, it can be in any proportions of both states at once. This is called superposition. But as soon as you test its value, say, by sending the photon through a filter, it has to decide to be either vertically or horizontally polarized. So as long as it’s unobserved, the qubit is in a superposition of probabilities for 0 and 1, and you can’t predict which it’ll be. But the instant you measure it, it collapses into one of the definite states.
Superposition is a game changer. Four classical bits can be in one of two to the power of four different configurations at a time. That’s 16 possible combinations, out of which you can use just one. Four qubits in superposition, however, can be in all of those 16 combinations at once. This number grows exponentially with each extra qubit. Twenty of them can already store a million values in parallel. A really weird and unintuitive property qubits can have is Entanglement, a close connection that makes each of the qubits react to a change in the other’s state instantaneously, no matter how far they are apart. This means when measuring just one entangled qubit, you can directly deduce properties of its partners without having to look.
Qubit Manipulation is a mind bender as well. A normal Logic gate gets a simple set of inputs and produces one definite output. A quantum gate manipulates an input of superpositions, rotates probabilities, and produces another superposition as its output. So a quantum computer sets up some qubits, applies quantum gates to entangle them and manipulate probabilities, then finally measures the outcome, collapsing superpositions to an actual sequence of 0s and 1s. What this means is that you get the entire lot of calculations that are possible with your setup, all done at the same time.
Ultimately, you can only measure one of the results and it’ll only probably be the one you want so you may have to double check and try again. But by cleverly exploiting superposition and entanglement, this can be exponentially more efficient than would ever be possible on a normal computer. So, while quantum computers will probably not replace our home computers, in some areas, they are vastly superior. One of them is database searching. To find something in a database, a normal computer may have to test every single one of its entries.
Quantum computers algorithms need only the square root of that time, which for large databases, is a huge difference. The most famous use of quantum computers is ruining IT security. Right now, your browsing, email, and banking data are being kept secure by an encryption system in which you give everyone a public key to encode messages only you can decode. The problem is that this public key can actually be used to calculate your secret private key. Luckily, doing the necessary math on any normal computer would literally take years of trial and error. But a quantum computer with exponential speed-up could do it in a breeze. Another really exciting new use is simulations.
Simulations of the quantum world are very intense on resources, and even for bigger structures, such as molecules, they often lack accuracy. So why not simulate quantum physics with actual quantum physics? Quantum simulations could provide new insights on proteins that might revolutionize medicine. Right now, we don’t know if quantum computers will be just a specialized tool or a big revolution for humanity. We have no idea where the limits of technology are, and there’s only one way to find out.

Huawei Matebook 13: Macbook Air killer
Huawei’s Matebook X which was released last year was considered as the MacBook Pro killer as it provided a lot of features which the MacBook Pro provided at a much affordable price. And this year, Huawei is back with Huawei Matebook 13 which offers specification between the ultra-slim Matebook X and the pocket-friendly Matebook D.
With Matebook 13’s premium Aluminum alloy and metal unibody finish, Intel Whiskey lake processor and thin bezel display, it can be clearly observed as a competitor for the Apple’s new 2018 MacBook Air. The release took place at CES 2019. Let’s have a closer look at the details of Matebook 13.
Starting with the display, it has 13-inch 3:2 touchscreen display which is super sharp with 2,160 x 1,440 resolution. Display provides rich colors with ample viewing angles. Taking a look towards the bezels, company says they are 4.4mm thin providing 88 percent screen to body ratio which is 6 percent more than the rivals MacBook Air with 82 percent screen to body ratio.
Moving to the keyboard, Matebook 13 offers a bigger touchpad than usual which will help you with better space and provide the rich user experience. Matebook 13 comes with an edge-to-edge comfortable keyboard with a 1.2mm travel between each key which is efficient to provide smooth and fast typos which makes it a thumbs up for those who hate Macbook Air’s low-travel keyboard although it is also pretty good. The keycaps barely come out and are not too loud or clicky. It has embedded fingerprint sensor on the power button which makes it easier to wake the computer up by just scanning the finger. With fingerprint sensors come to the security and to enhance it, Huawei has provided an independent security chip for storing the biometrics.
Let’s have a look over the heart of the machine. The Matebook 13 is very capable machine in terms of processing. The device will have two configurations in the US. The higher-end version packs in eight-generation Intel Core i7-8565U chipset coupled with NVIDIA GeForce MX150 graphics card, on the other hand, low-end version ships with Intel Core i5 and Intel’s UHD620 graphics. Both the versions of Matebook 13 will have 8GB of RAM which will be standard considering the price range. The Matebook 13 having quad-core will be having a good multitasking ability which will be a serious upgrade than the MacBook Air which includes a dual-core processor.
Although providing the great performance the weight and thickness of the device matters a lot. The Matebook 13 comes with a 14.9mm thickness which company says is 6 percent thinner than the 2k18 MacBook Air which has 15.9mm thickness. Although the Matebook 13 is thinner than the MacBook Air, it weighs 2.82 pounds which is heavier than the 2.75 pounds MacBook Air.
The Matebook 13 has squeezed a lot of powerful chipsets in such a small device which they mention is due to Shark Fin 2.0 thermal setup which has the capability to handle 8,000 rpm without overheating the device. Huawei has provided dual fan system placing them between the CPU and GPU which enables to separate the heat and also accomplish 25 percent higher volume than a traditional fan. The company also says that cooling system uses an “intelligent filtering solution” which is claimed to manage performance and reduce the fan noise.
Huawei also praised the Shark Fin 2.0 setup for helping them to dedicate almost 50 percent of the laptops underhood space to embed massive 42Whr battery but it is bit smaller as compared to the 57Whr battery of Macbook Air. According to the Huawei’s claim, the low-end version, which is Core i5 Matebook 13, will last up to 10 hours while playing a 1080p video which will be great if it is able to hold on its words.
Following the previous models of Matebooks, the Matebook 13 also comes with two USB-C ports and one headphone jack. But Huawei has included a dock which places in USB – A port, USB-C port, VGA and HDMI port as well. Webcams are important for the video conferences and to help with it, the Matebook 13 houses a one-megapixel camera into its bezel, which makes it at a better place as compared to Matebook X Pro which hid the webcam under one of the keys in the keyboard.
With a webcam you also need good speakers to make the video conferences lively and to do so, the Matebook 13 has two speakers docked into the keyboard with Dolby support giving out the crisp and clear sound.
Huawei also provides a 65W USB-C power adapter which can be used for fact charging the laptop. The Matebook 13 is claimed to provide 2.5 hours of “office work” which may include working with spreadsheets, emails, internet surfing etc. when charged for 15 minutes.
At last, if we list the highs of the device it will go as follows:
- High performance with Whiskey Lake processor
- Efficient design making is slim and light
- High screen to body ratio
- Affordable price
The Matebook 13 truly looks a well-built laptop to compete with Apple Macbook Air. The base version of Matebook 13 which includes Core i5 with 256GB SSD and 8GB RAM will be available in Silver color and will cost $999 and the higher end version with Core i7 with NVIDIA GeForce MX150 graphics and 512GB SSD will start from $1,299. The Matebook 13 will be on sale from January 29 on Amazon and Newegg.
WhatsApp will not work in this Old Phones.
The Facebook-owned worlds most popular instant messaging app have announced that it will discontinue their support for certain Old Mobile phones and Operating Systems. Whatsapp support would end for certain mobile Operating Systems after 31st December 2018 (today).
Earlier Whatsapp have stopped there services on the smartphones like Nokia Symbian S60, BlackBerry OS, BlackBerry 10, and Windows Phone 8.0 OS. And Now there are stopping services for the Devices which runs on Nokia S40.
Last Year, Whatsapp had being stopped working on the Devices like BlackBerry 10, BlackBerry OS, Nokia Symbian S60, Windows Phone 8.0, Nokia S40, Android versions 2.3.7 and older, iPhone iOS 7 and older.
To recall, the Nokia S40 was one the most popular smart feature phone a few years back, but after acquisition by Microsoft the OS lost its existence.
The reason for not further supporting this OS was the Simple and straight answer from the Whatsapp team. “Tech Industry is going way fast and newer Smartphones are evolved and developed every year. And to make Whatsapp compliant for the Latest Devices, we need to modify new Feature and Old OS is not able to support our updates and so we are discontinuing support for this Devices”.

What is Flipkart?
Flipkart is India’s Amazon. It’s the country’s largest online retailer. In 2018 retail giant Walmart announced its intention to acquire a controlling stake in the company for $16 billion, making this the largest e-commerce acquisition, ever.
Flipkart was founded here in Bangalore in 2007 by Sachin Bansal and Binny Bansal, two Indian software engineers, that happen to share the same surname. They both worked for Amazon in the U.S. before returning to India to start their company.
Like Amazon, Flipkart began as an online bookstore. In its first full year of business, it delivered nearly three and half thousand shipments of books. Now its website has 10 million page visits a day and sells more than 80 different categories of goods, which includes everything from food processors to yoga mats.
This expansion has been supported by the company’s own digital ecosystem. In 2009 it founded Ekart, its in-house supply chain arm.
Ekart is now India’s largest logistics company delivering 10 million shipments a month for Flipkart, as well as independent brands and sellers. It also owns PhonePe, an app the company acquired in 2016, which helps facilitate electronic payments throughout the country. In addition, Flipkart’s purchase of two of India’s leading online fashion retailers, Myntra and Jabong ensured the company remained the leading player in India’s online retail industry.
Flipkart’s strong position in the market attracted $1.4 billion of investment in 2017 from the Indian e-commerce market as a whole is set to quadruple to $200 billion in the next eight years, and by 2034 it’s predicted to surpass the U.S. as the second largest e-commerce market in the world.
The predicted growth in e-commerce has increased competition between the big online retailers. Amazon has been taking on Flipkart in its own backyard. Both have been offering massive sales and discounts pegged to Indian festivals as they battle it out for more customers.
While Amazon’s size and profitable cloud computing service allows it to absorb these costs, Flipkart has suffered losses in its struggle to compete. However, the Flipkart Group as a whole still has the largest share of the market and remains the e-commerce leader in India.
Walmart’s online sales, however, account for just a little more than three and a half percent of its business in the U.S. Acquiring Flipkart gives them a considerable foothold in the sector. Yet when news of the deal broke, the American retailer’s shares tumbled four percent with investors concerned that the company had a long way to go before becoming profitable. The acquisition of a loss-making business also cut Walmart’s profits at the end of 2018 and its earnings outlook for 2019.
The company also warned that e-commerce growth would be slower next year. For Flipkart, Walmart’s investment is seen by many as a major boost to the company’s logistical operations. It will also help it move into new areas like online groceries. Along with a strong food supply chain, Walmart’s financial support will also help Flipkart keep prices low in its battle with Amazon.
Several key investors have exited the company, including co-founder Sachin Bansal, and they leave with hefty profits. Venture capital firms Accel and Tiger Global invested when Flipkart was valued at just $50 million. They have now pocketed more than 400 times what they invested and still retain some shares.
Softbank is also a big beneficiary of the deal. Its Vision Fund invested $2.5 billion in 2017 and in just over 12 months the Japanese company sold its 20% stake for $4 billion.
Co-founder Binny Bansal had planned to stay on as the company’s chief executive but resigned after an internal investigation into serious personal misconduct following an accusation of sexual assault. He still owns 4.2% of the company and remains a director on the board. Amid the controversy Walmart increased its stake in the $20 billion company from 77 percent to 81.3 percent, offering another sign of its support of an online retail market that is still small by global standards.
The value and sale of Flipkart to a major corporation like Walmart will likely encourage investors to see India’s e-commerce market as an area of growth. Already the Indian startup Ola is competing fiercely with Uber in the taxi aggregation market and both have Softbank as a major shareholder.
As the world’s major tech companies focus more of their attention on India, Flipkart may be the first of many start-up success stories emerging from the growing e-commerce space.
So, do you think Flipkart has a chance against Amazon? Comment below to let us know.
