The 3 Types of Quantum Computers and Their Applications

It’s an exciting time in computing.

Just days ago, Google’s AlphaGo AI took an insurmountable lead in the 3,000 year-old game of Go against the reigning world champion, Lee Sedol. In a five-game series, the score is now 3-1 for the machine with one game left on March 15, 2016 in Seoul, South Korea.

While IBM’s Deep Blue beat reigning chess champion Garry Kasparov in 1997 by using brute force, Go is a game with more possible moves than atoms in the known universe (literally). Therefore, the technology doesn’t yet exist to make such calculations in short amounts of time.

Google had to take a different approach: to beat the grand master, it needed to enable AlphaGo to self-improve through deep learning.

AlphaGo’s historical decision is a milestone for artificial intelligence, and now the technology community is anxiously waiting to see what’s next for AI. Some say that it is beating a human world champion at a real-time strategy game such as Starcraft, while others look to quantum computing – technology that could raise the potential power of AI exponentially.

What is Quantum Computing?

While everyday analog computing is limited to having a single value of either 0 or 1 for each bit, quantum computing uses quantum bits (qubits) that are simultaneously in both states (0 and 1) at the same time.

The consequence of this superposition, as it’s called, is that quantum computers are able to test every solution of a problem at once. Further, because of this exponential relationship, such computers should be able to double their quantum computing power with each additional qubit.

Types of Quantum Computers

There are three types of quantum computers that are considered to be possible by IBM. Shown in the above infographic, they range from a quantum annealer to a universal quantum.

The quantum annealer has been successfully developed by Canadian company D-Wave, but it is difficult to tell whether it actually has any real “quantumness” thus far. Google added credibility to this notion in December 2015, when it revealed tests showing that its D-Wave quantum computer was 3,600 times faster than a supercomputer at solving specific, complex problems.

Expert opinion, however, is still skeptical on these claims. Such criticisms also shed light on the major limitation of quantum annealers, which is that they may only be engineered to solve very specific optimization problems, and have limited general practicality.

The holy grail of quantum computing is the universal quantum, which could allow for exponentially faster calculations with more generality.

However, building such a device ends up posing a number of important technical challenges. Quantum particles turn out to be quite fickle, and the smallest interference from light or sound can create errors in the computing process.

Doing calculations at exponential speeds is not very useful when those calculations are incorrect.

The Market and Applications

IBM highlights just some of the possibilities around universal quantum computers in a recent press release:

A universal quantum computer uses quantum mechanics to process massive amounts of data and perform computations in powerful new ways not possible with today’s conventional computers. This type of leap forward in computing could one day shorten the time to discovery for life-saving cancer drugs to a fraction of what it is today; unlock new facets of artificial intelligence by vastly accelerating machine learning; or safeguard cloud computing systems to be impregnable from cyber-attack.

This means that quantum computing could be a trillion dollar market, touching massive future markets such as artificial intelligence, robotics, defense, cryptography, and pharmaceuticals.

However, until a universal quantum can be built, the market remains fairly limited in size and focused on R&D. Quantum computing is expected to surpass a market of $5 billion market by 2020.

As a final note: its worth seeing where quantum computing sits on Gartner’s emerging technology hype cycle:

Gartner still describes it as being “10 years or more” away from reaching the plateau.

Internet Browser Market Share (1996–2019)

Web browsers are a ubiquitous part of the internet experience and one of the most commonly used digital tools of the modern era.

Since the first rudimentary interfaces were created in the 1990s, a number of browsers have entered the market, with a select few achieving market dominance over our access to web content.

Today’s bar chart race video, by the YouTube channel Data is Beautiful, is a nostalgic look back at how people used to access the internet, from Mosaic to Chrome.

The First Wave of Browsers

Simply put, web browsers are the software applications that act as our portal to the internet. Today, aside from the occasional pop-up box, we barely notice them. In the early ’90s though, when the web was in its infancy, the crude, boxy interfaces were a revolutionary step in making the internet usable to people with access to a computer.

The first step in this journey came in 1990, when the legendary Tim Berners-Lee developed the first-ever web browser called “WorldWideWeb” – later renamed Nexus. Nexus was a graphical user interface (GUI) that allowed users to view text on web pages. Images were still beyond reach, but since most connections were dial-up, that wasn’t much of a limitation at the time.

Nexus browser example

The precurser to the modern browser was Mosaic, originally developed as a temporary project by the the University of Illinois at Urbana–Champaign (UIUC) and the National Center for Supercomputing Applications (NCSA).

After his graduation from UIUC in 1993, Marc Andreessen teamed up with Jim Clark, the founder of Silicon Graphics, to produce a commercial version of the browser. The resulting software, Netscape Navigator, became the first widely used browser, moving the internet from an abstract concept to a network that was accessible to everyday people. The company soon staged a wildly popular IPO, which saw the 16-month-old startup reach a valuation of nearly $3 billion.

Naturally, the fanfare surrounding Netscape had captured Microsoft’s attention. Immediately after Netscape’s IPO, the first version of Internet Explorer (building off a licensed version of Mozilla) was released. The browser wars had begun.

The Internet Explorer Era

In 1995, Bill Gates was looking to capitalize on the “Internet Tidal Wave”, and was up to the challenge of eating into Netscape’s market share, which stood at about 90%.

A new competitor “born” on the Internet is Netscape. We have to match and beat their offerings…

– Bill Gates

Ultimately, Netscape was no match for Internet Explorer (IE) once it was bundled with the Windows operating system. By the dawn of the new millennium (beware Y2K!) the situation had reversed, with IE capturing over 75% of the browser market share.

With Netscape mostly out of the picture, IE had a stranglehold on the market. In fact, Microsoft’s position was so comfortable that after IE6 was released 2001, the next full version wouldn’t ship until 2006.

It was during this time that a new player came onto the scene. Mozilla Firefox was officially launched in 2004, seeing over 60 million downloads within its first nine months. For the first time in years, Microsoft began to feel the heat of competition.

Goliath and Goliath

Despite the growing popularity for Mozilla Firefox, it was a browser backed by another tech giant that would eventually lead to IE’s downfall – Google Chrome.

Chrome was pitched to the public in 2008 as “a fresh take on the browser”. While Microsoft struggled with open web standards, Chrome’s source code was openly available through Google’s Chromium project.

By 2011, Firefox and Chrome had eroded IE’s market share to below 50%, and a year later, Chrome would end Internet Explorer’s 14-year reign as the world’s top internet browser.

Today, the browser market has come full circle. Chrome has now become the dominant browser on the market, while competitors fight to increase their single-digit market shares. IE has dropped to fourth place.

Looking Back at the Peaks

In the 25 years since Netscape gave people access to the internet, a few browsers have had their moment in the sun. Here are the years of peak market share for all the major browsers:

BrowserPeak Market SharePeak Year
Netscape Navigator90%1995
Internet Explorer95%2004
Opera3%2009
Mozilla Firefox32%2010
Safari7%2012

Once a browser becomes popular, it can be incredibly difficult to carve into its market share. Even during the height of the iPhone era, Apple’s browser, Safari, was only able to manage a 7% market share.

For now, it looks like Chrome will continue to be the world’s preferred method of experiencing the internet. If Chrome’s current trajectory continues, it could become the third major browser to surpass a 90% market share.

The Sum of Its Parts: The Smartphone Multiplier Market

Every day, 3.3 billion people rely on their smartphones to stay connected. The products and services enabling this—the smartphone multiplier market—is now worth $459 billion.

The Sum of Its Parts: The Smartphone Multiplier Market

There’s a 60% chance you’re reading this article on a smartphone right now—a testament to how ubiquitous these devices have truly become in our lives.

We rely on smartphones every waking minute to stay connected. However, the various products and services—also known as the smartphone multiplier market—that allow us to use these devices in the first place can often be an afterthought.

Today’s chart uses data from Deloitte Insights to show just how sizable this ecosystem is becoming, and why it’s heating up as a battleground for big technology companies such as Apple, Alphabet, and Amazon.

The Smartphone Plateau

There are over 3.3 billion smartphone users in the world today.

The smartphone economy—estimated to pull in $944 billion in total revenue in 2020—is so massive that it rivals the GDP of countries like Indonesia and the Netherlands.

At the moment, the smartphones themselves contribute over half the market value. Despite the continued hype surrounding the release of new models, global unit shipments of smartphone devices appears to have reached a saturation point:

Smartphone Sales

There are two theories as to why shipments are leveling off. First, product innovation is more iterative today than in the past, which means there are fewer groundbreaking features to entice consumers into purchasing new devices. A second factor is that people are simply holding onto their devices for longer than in the past.

As device sales plateau, tech giants are diversifying efforts to find new ways to lure customers back in—and another related market is growing more lucrative as a result.

What is a “Smartphone Multiplier”?

When people think of the smartphone market, hardware likely springs to mind first, but an equally important part of the equation is the plethora of apps, services, accessories, and complementary devices that help us connect with the digital world.

The ecosystem of these products and services are known as smartphone multipliers. According to Deloitte, this ecosystem will drive $459 billion of revenues in 2020, an impressive 15% increase from the prior year.

The market can be broken down into three main categories:

CategoryMarket Value (2020e)Sub-categories
Content$312B
(68% of total)
$176B: Mobile ads
$118B: Apps
$10B: Music
$8B: Video
Hardware$111B
(24% of total)
$77B: Accessories
$25B: Wearables
$9B: Smart speakers
Services$37B
(8% of total)
$18B: Insurance
$12B: Repairs
$4B: Others
$3B: Storage

Largely driven by mobile advertising and app sales, content is by far the largest subcategory, accounting for 68% of revenues:

  • Mobile advertising surpassed TV as the largest advertising channel in 2019, partially thanks to the relentless growth of online video and social media, making ads virtually unavoidable on a smartphone.
  • Gaming apps are benefiting from the immense processing power of today’s smartphones—and will bring in over two-thirds of total app revenue in 2020. Apple’s app store brought in approximately $1.8 billion in sales between Christmas Eve and New Year’s Day alone.
    • If you’ve ever owned a pair of headphones or a powerbank, it’s easy to understand why accessories are the third-largest subcategory in the smartphone multiplier market. With more people ditching the cable for wireless headphones, this subcategory is also set to grow even more.

      The Next $1T Economy?

      In the U.S., 73% of adults go online several times a day or almost constantly, which makes it clear that they aren’t going to give up their smartphones anytime soon.

      As a result, smartphone multipliers will continue to evolve and flourish, presenting a unique opportunity for investors and businesses.

      Altogether, it’s expected that the smartphone multiplier market will grow between 5 and 10% annually through 2023, likely propelling the entire smartphone economy past the $1 trillion benchmark in the coming years.
