Understanding Quantum Computing

What Is It?

Computer science’s application of quantum theory is known as quantum computing. The behavior of energy and matter at the atomic and subatomic scales is explained by quantum theory.  Subatomic particles, such electrons or photons, are used in quantum computing. These particles can exist simultaneously in two states (i.e., 1 and 0) thanks to quantum bits, or qubits.

Linked qubits may theoretically “use the interference between their wave-like quantum states to accomplish calculations that would otherwise take millions of years.”  In order to encode information in bits, traditional computers nowadays use a binary stream of electrical impulses (1 and 0). Compared to quantum computing, this limits their ability to process information.

Understanding Quantum Computing

The 1980s saw the emergence of the quantum computing field. It was found that some computational issues could be solved more effectively by quantum algorithms than by classical ones.

Quantum computing has the capacity to sort through enormous quantities of options and identify potential answers to difficult issues. Quantum computers use qubits, as opposed to classical computers, which store information as bits with either 0s or 1s. Qubits store information in a multidimensional quantum state that interacts with 0 and 1.

Some of the biggest companies have taken notice of this enormous processing capacity and the anticipated size of the market for its utilization.

Importance of Quantum Computing

Over the next ten years, quantum computing is expected to change a number of business sectors, including banking, medicine, machine learning, and artificial intelligence. Money invested by investors, governments, and businesses pursuing total quantum dominance is the main driver of quantum computer advancements.

The “National Quantum Initiative,” which aims to expand the quantum computing area, was introduced by the American government in 2019. Additionally, the government set aside $1.2 billion for the promotion of the quantum world. Like the United States, China is advancing its plans for quantum technology by spending $10 billion to create the “National Laboratory for Quantum Information Sciences.”

It is vital to comprehend the significance of quantum computing as it gets closer to becoming a reality.

Application and Advantages of Quantum Computing

The domains of security, finance, military affairs and intelligence, drug development, aircraft design, utilities (nuclear fusion), polymer design, machine learning, artificial intelligence (AI), big data search, and digital manufacturing could all benefit substantially from quantum computing. Information sharing could be made more secure with the help of quantum computers or to enhance radars’ capacity to find missiles and aircraft. The environment and maintaining clean water with chemical sensors is another area where quantum computing is anticipated to be helpful.

Here are a few advantages that could come from quantum computing:

  • Quantum computing may allow financial institutions to create investment portfolios for individual and institutional clients that are more effective and efficient. They may concentrate on enhancing fraud detection and developing better trading simulators.
  • Quantum computing could be used in the healthcare sector to create novel medications and genetically focused treatments. It might also fuel more sophisticated DNA studies.
  • Quantum computing can be used to create more secure data encryption and methods for detecting system intrusions using light signals.
  • Systems for planning traffic and designing more effective, safe aircraft can benefit from quantum computing.

Development of Quantum Computers


By 2029, Google expects to have built its quantum computer at a cost of billions of dollars. To aid with the achievement of this objective, the business established the Google AI campus in California. Google might introduce a cloud-based quantum computing service once it is created.


By 2023, IBM hopes to have a 1,000-qubit quantum computer operational. For the time being, IBM gives companies conducting research, academic institutions, and laboratories access to its equipment through its Quantum Network.


Through the Azure Quantum platform, Microsoft provides businesses with access to quantum technology.


Financial services companies like JPMorgan, Chase, and Visa are interested in quantum computing and related technology.

Is quantum computing the technology of the future?

Quantum computing is still a young discipline. As we’ve seen, the technology is still not flawless and difficult to use, and still with a lot of unknowns. However, the usage of quantum computers now and in the future may alter how we perceive our surroundings.

Quantum computers have a lot of potential for producing intricate models and simulations as well as substantially quicker problem-solving. It remains to be seen if we will be able to completely realize that promise. If nothing else, we may anticipate more technological improvements in the years to come because organizations like Google and IBM have made significant investments in the field.

Final Verdict

Comparing traditional and quantum computing is like night and day. Qubits, which can simultaneously be 1 or 0, are used. The only possible values for bits in traditional computers are 1 and 0. Quantum computing is, therefore, significantly faster and more potent. It is anticipated that it will be applied to a variety of exceedingly difficult, valuable tasks. It currently has several limits, but many powerful businesses across a wide range of industries are ready to use it.
