The Future with Quantum Computing

Andreas Sjöström
November 15, 2021

With advances in technology like smartphones, AI, and space travel, it seems impossible that we may still be living in the dark ages. But we are. When looking at the world and how it can be affected by the advancements in quantum computing, you can see that quantum computing can disrupt every industry.

How do Quantum Computers work?

Let’s start with the basics; classical computers work by manipulating binary digits, meaning that they use 1’s and 0’s or “bits.” Quantum computers break free of classical computing by substituting “bits” with “qubits”.  Qubits, or quantum bits, operate according to the laws of quantum mechanics. For those who don’t have a background in engineering, this is the theory that physics works differently at the atomic and subatomic scale.  In the simplest terms for lay people, quantum computing is exponentially more powerful, making it faster, more accurate and efficient than your traditional computer at home. 

Why Quantum Computing?

When people ask me this question, I always have trouble answering. Trying to encompass all the incredible abilities and applications of what we can do with Quantum Computers is like asking someone to tell you the capacity of the internet in a few short sentences. While I can’t list everything here, some notable abilities of quantum computers include:

  1. Recently, the Google quantum computer displayed its power by completing a mathematical equation in 200 seconds that would have taken a traditional computer 10,000 years.
  2. Quantum Computers will change the way we look at medicine. Creating the ability to consider multiple factors at once, medical treatment will be far more precise and individualized, allowing us to ditch the “umbrella approach” to diagnosis and achieve a more accurate personalized holistic approach.
  3. The high-level computing ability is optimal in the financial sector. You can expect to see significant improvement in complex processes like risk aversion, market predictions, and trading optimization, leading to more tools for investors and firms.  This in turn can result in greater financial gain for individuals as well as world economies. 

Changing the World of Health

This pandemic showed us the importance of having a high-quality and accurate health care system. Now more than ever, it is essential for our hospitals and health care professionals to be equipped and utilize the most advanced tools possible to help patients.


Currently, diagnosing patients is invasive, complex, and costly. Additionally, you must factor in human error, with the diagnostic inaccuracy rate falling in the 5-20% range[1]. Current hospital technology like MRI, CT, and X-Ray machines all produce images that are analyzed and processed to identify issues. These machines come with many challenges such as disruptions due to movement, making the image difficult to process. Quantum Computers would ease this process by allowing for much more accurate medical image analysis by performing image matching on massive data sets. While a doctor may only be able to reference a few thousand images, a quantum computer can reference every single accessible medical image to help identify medical issues.


When treating patients, doctors know that one of the most critical factors is early diagnosis for a successful treatment protocol. It can often be difficult to accurately prescribe people medicine as they are not aware of all the factors that fall into diagnoses. Every year, nearly 10,000 people die due to medication errors which causes a financial strain of almost 40 billion dollars treating roughly 7 million patients who have suffered from these errors[2]. One way of reducing this is beginning to understand the workings of our medicine at a cellular level. For example, by considering the genomic features of cancer cells and the chemical properties of drugs, we can begin to explore models that can predict the effectiveness of cancer drugs at a granular level[3]. Quantum Computing would allow for further acceleration in this space, changing the way we approach medicine. Efficient. Powerful. Accurate. These are the attributes that make quantum computing such disruptive technology in the coming future.
