Quantum computing has long been regarded as the next “big thing.” Now it’s looming ever larger on the horizon, and graphene is part of the reason for that.
Dr. Rajamani Vijayaraghavan, head of the Quantum Measurement and Control Laboratory at the Tata Institute of Fundamental Research (TIFR), told Swarajya Magazine in September 2020 that an everyday quantum computer — i.e., one “that is practical and commercial in nature,” as he put it — is still a “couple of years” down the road.
But there have been strides in that direction for several years, and experts relish all that these computers might have to offer. So grand is their processing power, in fact, that it is believed they will be able to meet some of the world’s greatest challenges in a fraction of the time it takes classical computers. They can hasten the development of environmentally friendly technology, for instance. They can shorten the timeline for the development of drugs and vaccines. They can make market forecasting more sophisticated and supply chains more efficient.
The caveat is that the quantum bit (i.e., the qubit), the basic building block of quantum computers, is notoriously sensitive to its environment. In fact, until last year they always had to be supercooled at minus-272 degrees C (1 kelvin). They simply could not operate at higher temperatures.
This is one of the places graphene could come into play. Researchers, already aware of the substance’s superconductivity, discovered in 2020 that graphene was the first material capable of serving simultaneously as a superconductor, insulator and ferromagnet. That resulted in the further revelation, in February 2021, that when three layers of graphene were twisted — one more layer than had previously been attempted — the material’s conductivity was enhanced to the point that scientists could envision them operating at room temperature.
Also in February 2021 came a further development in the field of valleytronics, which seeks to exploit a property in graphene known as “the valley,” which is not unlike the spin of electrons in other materials. This new method again involves twisting layers of graphene — this time two, instead of three — after they are placed between a ferromagnetic insulator. It is expected that this method will increase processing speeds.
A few months earlier, in October 2020, scientists discovered that a bolometer, a device that detects the tiniest of energy changes in quantum computers — changes that can negatively impact qubits — operated far more quickly and efficiently when it was made of graphene as opposed to gold palladium alloy, as had previously been the case.
Taken together, these developments indicate that we are drawing ever nearer to seeing quantum computers become a reality. While experts caution that there are “many, many hurdles yet to overcome,” these are promising strides in the right direction.
Whether we realize it or not, we are constantly impacted by cloud storage. Perhaps you begin your work day by opening a Google Doc or an email sent to you via Gmail. Both of those platforms are dependent upon cloud storage. Or perhaps you spend your lunch hour checking Facebook, Instagram or YouTube. All those platforms make use of it as well.
It’s all around us, whether we’re downloading cat videos or toiling away on a big project, and impacts us most directly when we want to back up or store our own personal data — as will increasingly be the case. Spurred by the advent of such cloud-storage systems as Google One, Amazon Cloud and OneDrive, the cloud storage market size is expected to be $49.13 billion in 2021, then jump to $297.54 billion by 2028, a CAGR of 25.3 percent.
Cloud storage is particularly popular in the business world, as some 85 percent of enterprises around the world use it.
But what is it, really?
It consists not of storage in some mystical place free of Earth’s bounds (as its name might suggest), but in far-off data centers, where files of all sizes are secured and backed up but also constantly accessible to owners via the Internet. In fact, users — who pay for the service either via subscription or on a per-consumption basis — can access their information courtesy of any device.
It is, in other words, a sizable step beyond storing information on thumb drives or external hard drives. It has also been particularly useful during the coronavirus pandemic, given many companies’ pivot to remote work. Files can be shared, and it is possible for multiple users to access a file at the same time. In other words, collaborative projects are a breeze when cloud storage is involved.
Security is, of course, a constant concern, especially given how much data is going to be out there in the years to come. While there were some 33 zettabytes of data (the equivalent of 33 trillion gigabytes) throughout the world in 2017, that total is expected to mushroom to 175 zettabytes in 2025. And rest assured that cybercriminals are always lurking.
The countermeasures adopted by cloud servers are considerable. Most take steps such as encrypting files, storing them behind firewalls, and availing users of two-factor authentication. Some even resort to artificial intelligence to scan their system for weak spots.
In addition, most services make multiple copies of files and store them at various data centers — a practice known as redundancy — to preclude their loss in a natural disaster. A 2019 report even noted that there are occasions where these services back up data on magnetic tape, often considered a relic of a bygone era but actually a reliable, secure means of storage.
The long and short of it is that we continue to be enveloped by the cloud. It is all around us, at all times, and enables us not only to store an ever-increasing amount of data, but also to access and share it. All of that is valuable — particularly the latter, and particularly now.
In 2016, Frederic Kerrest, COO and co-founder of the identity tech startup Okta, told Inc. that business was only “in the first inning” of cloud computing adoption. It is safe to say that we have moved along to subsequent innings. Snowflake, a Silicon Valley cloud data warehousing company, on September 15, 2020 raised $3.4 billion in what is the largest software IPO ever.
Now just about everyone wants his or her turn at bat (to torture the baseball metaphor a bit more).
Precious few industries have been left unaware of the advantages the cloud can offer. It is estimated, in fact, that 90 percent of companies are now reaping its benefits, and that spending on cloud infrastructure services will increase from $39.5 billion in 2019 to $63 billion by 2021.
Those benefits range from things like increasing accessibility, improving efficiency, and reducing the sheer size of a company’s data center to reducing an enterprise’s carbon footprint.
Of particular interest is the level of security the cloud provides. A 2019 post on Onehub noted that all businesses would be wise to follow the 3-2-1 backup plan, under which data is stored in two places on-site and a third off-site, thus negating the impact of a disaster such as a fire.
That same site shared some grim statistics about cybersecurity. Fully 21 percent of business files go unprotected, and 41 percent of companies leave over 1,000 files vulnerable to attack, including files that contain sensitive personal information. And just about half of cyberattacks are aimed at small businesses, while ransomware attacks have skyrocketed by some 350 percent each year.
The cloud obviously offers a much-needed layer of protection. Also pertinent — especially in this day and age, as the coronavirus pandemic rages — is the fact that the cloud offers businesses more flexibility in terms of remote work. No matter where an employee happens to be at any given moment, he or she can access a company’s data and applications. All that’s needed is the proper device and a working internet connection.
Here are four industries that have soared into the cloud:
- Education: With remote learning now a necessity in a great many places, the cloud offers the same flexibility it does to remote workers. Chad Stevens, leader for K-12 Education at Amazon Web Services, told EdTech Magazine that AWS affords students the opportunity to access educational resources, and in the case of the sprawling Los Angeles Unified School District, was integral to the setup of call centers for tech/remote support.
- Marketing/Advertising: Data is king, and cloud platforms allow those in such fields as marketing to gather information from various sources — and do so in real time. This obviously helps to spot emerging trends and markets, and thus get a leg up on the competition.
- Real Estate: As with other disciplines, agents and brokers in real estate benefit from accessibility while on the go. The cloud gives them the ability to store data, safely and securely — and have peace of mind in the event of, say, a hard drive gone bad.
- Healthcare: Telemedicine has taken on added importance during the pandemic, and is expected to be critical to this sector in the years ahead. That means, once again, that storing data in the cloud is of the utmost importance. In addition, patients have easy access to their own records, and thus a greater say in their own care than ever before.
The cloud looks incredibly promising for many businesses, in a variety of industries, as they look to meet current challenges and anticipate those in the years ahead. It offers accessibility, security and flexibility — and, perhaps most of all, peace of mind.
While 4G technology made possible high-speed mobile browsing and wearable connectivity, 5G promises that those wearables will become even more prominent, smaller, and more efficient. That goes for ones already in existence, like smartwatches and health trackers, and those still on the drawing board (like, believe it or not, tattooables).
How that happens comes down to 5G’s accessibility to the cloud, its lower latency, and its speed, which can theoretically be 100 times faster than 4G.
Real-time data transfer will now be possible, and some experts believe that in the not-too-distant future, virtually everything we wear (clothing, shoes, contact lenses, even sensors placed under the skin to track health data) will transform us into walking, talking connected devices.
Certainly skeptics remain, but Fortune cites International Data Corporation projections indicating that wearable sales will reach $49.4 billion this year, and soar to $69.8 billion by 2024. Sanyogita Shamsunder, Verizon’s vice president of 5G Labs and Innovation, told Fortune that ‘2024 will in fact serve as an “inflection point,” as that will be the year that medical sensors will become commonplace.
Already available, Fortune notes, are smart glasses, smart earbuds (a.k.a. “hearables”) and yoga pants that make those wearing them aware if their yoga technique leaves something to be desired.
And those tattooables? While still in development, they are expected to be constructed of wafer-thin electric mesh, according to Fortune, which will enable them to store data and do things like deliver drugs.
The reason wearables are expected to shrink in size, according to TechRadar, is that they will no longer need physical space to store data; 5G can simply zip data right to the cloud. Instead, wearables of the near future will consist of ultrathin sensors, and little else.
An increase in sensors and a decrease in size is precisely what will cement wearables as part of the Internet of Things. Until now, we’ve mostly thought of wearables as items such as smartwatches that the user wears on their wrist. But these sensor-packed devices could just as easily be connected to objects rather than people to read and process data in real-time.
Consumers may also be happy to know that relieving some of the processor’s job means that a device’s battery will be more efficient. The ability to charge wirelessly within a wider range — up to 30 cm away — will allow devices to charge without cables or docks, even when in use.
All of this will take time, however. AT&T, Verizon and T-Mobile have all begun rolling out 5G, but it will be years before most of the country, let alone the world, has coverage. Then, manufacturers must create devices that harness the power of 5G.
In addition, there are privacy concerns about sensitive personal data being widely circulated, location data being easily accessible, and even foreign manufacturing threatening national security.
Such matters give one pause, to be sure. But for now, it’s full speed ahead for 5G, at 100 times the pace of the existing technology. While there are potential hurdles, there are also vast possibilities that make 5G’s future look extremely promising.
