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.

Now you can play PUBG for only 6 hrs / day
Player Unknown’s Battlegrounds (PUBG), the known and trending battle royal game that has sparked a wave of fan following in Asian country, seems to be obtaining daily usage restrictions.
Some players of the sport have rumored that the title serves health reminders and stops operating once an exact amount of your time.
The modification comes within the inside of reportable deaths and addiction issues over the sport.
6-hour restriction on PUBG Mobile
Multiple PUBG players have taken to Twitter to report that the mobile version of the sport’s problems a health reminder once 6-hour usage and so stops playing.
After this, once PUBG is launched, it serves a message saying “You’ve played the game for six hours today,” and prompts the user to return back at 5:30 am on the following day to continue taking part in.
All players in India will currently play the sport for under six hours per day. Players below eighteen can receive a reminder each 2 hours (at two and four hours of game time).
Health remainder on @PUBGMOBILE . One of my friend played it for 6 hours it seems an . #PUBG To the next level. @Im_Rahul16 Take care of your health daww.. 🤣😂 ¼ part of day well spent with @PUBG pic.twitter.com/6nOUTrvglh

So far, Tencent, the maker of the game, has not created an official announcement in respect to the introduction of those restrictions.
However, the screenshots doing rounds on the web clearly recommend that the corporate is willing to implement the aptitude shortly.
However, the announcement was created on the official discord server of the game wherever one amongst the moderators revealed the following message-
“Due to political concerns in India, a play time restriction of six hours has been imposed. This applies to all Indian players regardless of their age. The restriction does not affect players of other regions than India. Players below the age of 18 will receive a reminder after two and four hours, this before the six-hour restriction is reached.
Note: It may take some time for these changes to take full effect and apply to every Indian player.”
The only question as of now could be once it’ll happen at the large scale and the way the general public will react.
PUBG is insanely big popular in the youth of INDIA.
Over the previous few months, PUBG has raked large quality in Republic of India and alternative components of the planet.
The user-base of the sport has big therefore massive that folks have started raising addiction alarms, business for a state ban on the sport.
Notably, it’s already been illegal in Gujarat, due to multiple reports of death. And many players have been arrested in playing PUBG in public areas.
Apple Watch Caring like a Human – Saves Lives
Apple Watch has become a lifesaver on over one occasion and it adds another feather to the hat by saving a user with its timely designation. The inbuilt heart-rate device within the Apple Watch may be a corking feature obtainable within the most well-liked wearable out there and it’s attributable for correct readings from most of its users. In one such instance, Apple Watch prompted its user to travel to the hospital once detecting uncommon activity within the pulse.
Science Friday radio host Ira Flatow shared his grateful expertise with Apple Watch on Twitter on Thursday, once his brother’s life was saved by the Watch’s impromptu designation. in line with Flatow, his brother’s Apple Watch hit a warning upon striking >200bpm pulse rate and instructed he pay a visit to the hospital.
After obtaining checked up at the hospital, Flatow’s brother was diagnosed with cardiac arrhythmia, a condition wherever the resting pulse rate exceeds the traditional gait (beats per minute). for many adults, a resting pulse rate is considered traditional between 60-100bpm. something on top of 100bpm is considered risky and Flotow’s brother’s pulse rate had broken 200bpm, business for immediate medical attention.
After Flatow’s brother was admitted to the hospital, he found that the Apple Watch readings matched with those of the hospital medical instrumentality all the time. “During the fifteen hours I used to be at the hospital attached to the monitors, the monitors ne’er disagreed with my watch’s reading. I checked repeatedly,” Flatow tweeted quoting his brother.
2/ He says … “and BTW, during the 15 hours I was at the hospital hooked up to the monitors, my the monitors never disagreed with my watch’s reading. I checked MANY times.”

Even though Apple Watch’s intrinsic heart-rate device may be a reliable tool to discover uncommon pulse activity, the favored wearable remains not absolutely able to replace the advanced EKG machines. however, obtaining an early designation while not having to bear a series of tests in unsuspecting people is definitely a boon.
This is not the primary time Apple Watch has been attributable to saving lives. Recently, Gaston D’Aquino, a semi-retired diamond dealer, thanked Apple chief executive officer Tim Cook once his Apple Watch saved him from a dangerous heart condition, giving him “a new lease on life.” Apple Watch conjointly helped diagnose a teen’s urinary organ disorder and another user thanked Apple for sleuthing elevating pulse rate, that clothed to be an embolism.
Apple introduced watches’ 5.1.2 for its smartwatches, that enabled EKG to perform within the Apple Watch Series four and also the Irregular Rhythm Notification for all models. Ever since Apple Watch reportedly saved various lives.
DIGITAL HEALTH MARKET may value over $500 BILLION
The digital health market might reach a worth of $504 billion globally by 2025, and $7 trillion is spent on health care around the world per annum. That’s 10 % of the world’s GDP and also the biggest pay for global governments. health care wearables alone are expected to hit a market price of nearly $18 billion by 2021.
Apple has created no secret that it sees a future far away from the product just like the iPhone and iPad. CEO Tim Cook, in keeping with CB Insights, has aforementioned the health care market makes the smartphone sector look “small.” the corporate has discharged a Health Record and further its heart observance to the Apple Watch. The device conjointly has “fall” detection and an emergency SOS feature.
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.
