What Quantum Computing is and How it Will Change Everything

Last Updated on January 11, 2023

Quantum computing

Quantum computing is a rapidly emerging technology that has the potential to revolutionize the way we solve problems and conduct business. Unlike traditional computing, which is based on classical mechanics, quantum computing harnesses the principles of quantum mechanics to perform calculations at speeds that are orders of magnitude faster than current computers. Due to how swiftly it is becoming a reality, many businesses are keeping a careful eye on it.

The fact is that governments and businesses throughout the world, led by Google, Microsoft, and Intel, which aim to set the pace, are investing billions of dollars in the research and development of quantum technology.

It is our duty as business owners and executives to inform ourselves of the realities of these technologies. In this blog post, we will explore what quantum computing is, its current and potential applications, and how it will expand the tech industry.

What is Quantum Computing?

At its core, quantum computing is a method of performing calculations using quantum bits, also known as qubits. Unlike classical bits, which can only be in one of two states (0 or 1), qubits can exist in multiple states at once through a phenomenon known as superposition. Additionally, qubits can become entangled, meaning that the state of one qubit is dependent on the state of another qubit, even when they are separated by large distances. These unique properties of qubits allow quantum computers to perform calculations in parallel, making them much faster and more powerful than traditional computers.

Understanding Quantum Mechanics

In general, quantum mechanics examines minute objects. It seeks to redefine our current understanding of the behaviour of atoms and molecules by explaining.

By manipulating quantum behaviours, researchers are advancing the subject of quantum mechanics and creating new applications. Therefore, quantum physics is receiving a lot of attention at the moment, and I believe it will influence our daily activities in the future.

Quantum computers are essential tools for expediting the development of new materials, including new pharmaceuticals, solar panels, and polymers. They can carry out high-speed and accurate molecular simulations.

Within a few years, these machines will likely gain the so-called “quantum advantage,” which would allow them to outperform conventional computers at a particular, useful task.

How Quantum Computing Works

Compared to supercomputers, quantum computers are more elegant machines that use less energy. A laptop’s wafer is comparable in size to an IBM Quantum processor. A quantum hardware system, which is roughly the size of a vehicle and consists primarily of cooling devices to maintain the superconducting processor at its extremely low operational temperature, is also of this size. Bits are used by a traditional processor to carry out its functions. Qubits (CUE-bits) are used by a quantum computer to execute multidimensional quantum algorithms.


For it to be cool enough to operate, your desktop computer probably uses a fan. We need to keep our quantum processors at very low temperatures—just one-hundredth of a degree above absolute zero. We produce superconductors using super-cooled superfluids to accomplish this.


Certain components in our processors demonstrate another crucial quantum mechanical property at those extremely low temperatures: electrons pass through them without resistance. They are “superconductors” as a result.

Cooper pairs are formed when electrons move through superconductors. Through a process known as quantum tunnelling, these pairs can carry a charge beyond insulators or barriers. A Josephson junction is created when two superconductors are positioned on opposite sides of an insulator.


Josephson junctions serve as superconducting qubits in our quantum computers. We can regulate these qubits’ behaviour and get them to store, modify, and read out discrete pieces of quantum information by directing microwave photons at them.


A qubit isn’t particularly useful by itself. It can, however, pull off a crucial ruse by putting the quantum data it contains into a state of superposition that combines all qubit configurations that might be feasible. The superposition of qubit groups can produce intricate, multidimensional computational landscapes. In these settings, complex issues can be represented in novel ways.


A quantum mechanical phenomenon known as entanglement correlates with the actions of two distinct entities. Changes to one qubit directly affect the other when two qubits are entangled. Quantum algorithms take advantage of those connections to solve challenging issues.

Quantum Computing vs Classical Computing

A relatively young and developing area of technology is quantum computing. It improves on classical computing but takes a distinct approach to problem-solving. Although it was first proposed in the 1980s, it wasn’t until recently that we understood how powerful it could be if it were developed further and integrated into our daily lives.

A type of computing known as quantum computing has the potential to tackle issues that conventional computers are unable to. Qubits, which can exist in several states concurrently, are used in quantum computing in place of Bits. In contrast to a traditional computer that uses transistors, which can either be in a 1 or 0 state, a qubit exists simultaneously in both the 1 and the 0 states in this so-called superposition state.

Working with data in several dimensions at once is the main benefit of quantum computing. Due to this property, quantum computers can carry out numerous calculations at once and exponentially expand their processing capacity, addressing challenging issues that are hard for conventional computers to handle. The power of a quantum computer significantly rises as additional qubits are connected.

Real-World Applications of Quantum Computing

Online Security

The widespread adoption of quantum computing will have both positive and negative effects on internet security. Our current data encryption techniques will become ineffective. Nowadays, the majority of internet security measures rely on the fact that “breaking the code” takes a long time since computers have to process a lot of data.

On the other hand, quantum computers will be able to process this data quickly, leaving our computers, financial institutions, and personal data exposed. The good news is that significant advancements have been achieved in the creation of quantum encryption technologies, such as quantum key distribution, an incredibly secure communication method that employs a key to decipher a message. Due to the peculiar properties of quantum physics, no one can read the transmission if it is intercepted.

Drug Development

Drug discovery and development could advance dramatically with the help of quantum computers, allowing researchers to finally find solutions to issues that are currently insurmountable. These machines’ exceptionally high processing capacity will enable simultaneous quantum simulation reviews of many molecules, proteins, and chemicals, something that is currently impossible with a regular computer. This will speed up and improve the development of therapeutic possibilities compared to today.

Scientists, including those at the Roche pharmaceutical business in Switzerland, are hopeful that quantum simulations can hasten the creation of medications and vaccines to fend off diseases like Covid-19, influenza, and cancer, and perhaps even find a treatment for Alzheimer’s. Quantum simulations may also be able to substitute laboratory tests, cut research costs, and even lessen the necessity for human and animal testing.

Artificial Intelligence

Information processing needed to improve machine learning is ideally suited to quantum computing. Massive volumes of data may be analysed by quantum computers, which can then provide artificial intelligence robots with the feedback they require to improve performance.

Artificial intelligence robots benefit from a faster learning curve thanks to quantum computers’ superior ability to analyse data. Similar to humans, quantum computing-powered artificial intelligence machines can learn from mistakes and self-correct. In a relatively short period, quantum computers will allow AI to extend to numerous industries and technology will become much more reasonable.

Deeper analytics and new, quicker trading opportunities are just a few of the possible advantages that quantum computers could have for the financial sector. A lot of big organisations are interested in using quantum computing to speed up trade, transactions, and data flow. Banks are experimenting with quantum technology, including IBM and JPMorgan Chase, to determine what precise tasks it will be able to carry out on a large scale shortly.

Financial modelling is another potential application area that might benefit substantially from quantum computing. This results in speedier transactions and lower processing costs for financial institutions all over the world.

Traffic Control

The best routes will be quickly determined by quantum computers, enabling more efficient scheduling and lowering traffic congestion. For essentially the same reasons, quantum computers are valuable for enhancing supply chains, fleet operations, air traffic control, and delivery.

Improve Weather Predictions

Meteorologists will have a much better understanding of dangerous weather situations thanks to quantum computers’ ability to analyse all the data concurrently, enabling them to warn people and ultimately save lives, agony, and money. As better climate models are created with the help of quantum computers, we will also gain a more excellent knowledge of how our actions affect the ecosystem.


Quantum computers are about to have a big impact on businesses all across the world, transforming technology in ways we don’t yet completely understand. Enterprises must examine their options for embracing this new technology and ensuring that their workforce is prepared for what lies ahead.

The future of technology includes quantum computing, which could also play a significant role in the future of work, especially when it converges with other fields of study. To remain competitive in their respective industries, businesses should adopt quantum computing or, at the very least, learn about the technology.
