‘The unimaginable hardly takes time to turn into the reality" #
There was a time when we imagined carrying touchscreen phones in our pockets and getting obsessed with them. We are living in that phase now.
Even sci-fi turns into reality at a quantum level. At this stage, particles travel forward and backward in time with the ability to teleport. We are waiting for the quantum leap, envisioning how that ’leap? will change our view of the universe. That day isn’t that far either.
If you are someone keen to understand quantum computing but find it hard to approach, this article is for you.
What Is Quantum Computing? #
‘Quantum? is a term obtained from Physics. It is the minimal amount of a physical quantity that can independently exist. It is the lingo of Physics, something everyone talks about, but only a few people truly understand.
Quantum computing is the amalgam of Quantum Physics, Mathematics, and Computers. Their design tackles complex problems with ease.
Devices that perform quantum computing are called quantum computers. Their main task is to store and process data.
Quantum computers can prove extremely advantageous for certain tasks where they outdo the best supercomputers. In situations where there are numerous possible combinations, quantum computers gain an edge even over conventional computers by considering different combinations simultaneously.
Key Statistics — According to research, it is estimated that by 2025, the global quantum computing market would be worth $949 million. #
? According to another prediction, the world could have 2,000 to 5,000 quantum computers by 2030.
Conventional computers use bits for processing and storing information. Quantum computers use quits for this task.
How are Quits and Bits Different? #
Bits are in the form of 1s and 0s. Quits can stay in a state of 1s or 0s and 0s and 1s at the same instant. This speeds up the entire computation process. Between the states of 0 and 1, it can also exhibit multiple states.
This theory forms a possible explanation as to why quantum computing involves parallel universes. The simultaneous existence of states in quits could be because we observe them in multiverses simultaneously.
How Does Quantum Computing Work? #
Quantum computers are fragile and highly sensitive to noise and other environmental effects. To operate, they need conditions colder than outer space.
Quantum computing uses properties of superposition, entanglement, and interference for computation.
Superposition
The property of a quantum system to exist in multiple states simultaneously is superposition. Let’s understand this with a real-life example.
You flipped a coin in the air, and it landed on heads. However, when the coin was in the air, it was in two states, both heads, and tails. The coin in mid-air is showing the principle of superposition.
Entanglement
This property means connecting and intertwining objects permanently. Suppose you add one quit to a 50-quit quantum computer. Because of entanglement, the machine can now examine 250 states simultaneously.
You might have a billion quits at your disposal, but their use is limited if they don’t interact with each other. This is where entanglement helps. Entanglement connects all the quits, increasing the efficiency of the system.
Interference
Quantum computers generate answers in the form of probability. Repeating a question changes the response. The more times a question gets repeated, the closer the responses approach the correct answer.
To get answers from quantum computers, we require quantum codes. Quantum codes use wave-like properties.
These codes use interference to control the quantum states, cancel the wrong responses, and amplify the signals leading to the correct answer.
What are the Applications of Quantum Computing? #
Quantum computing is the key to the greatest performance boost in the history of automation. Like electricity, we expect quantum computing to revolutionize every industry and modernize our economy. We will witness changes in several areas of technology and science, observe advancements in medical care, and reshape several industries.
However, if we pull off that leap, that doesn’t mean we will have quantum phones nor will they replace conventional computers.
Here a few major applications of quantum computing.
Artificial Intelligence and Machine Learning #
The primary application of quantum computing is in artificial intelligence.
AI and machine learning are some of the most emerging fields right now. They have penetrated almost every industry and even our lives. With the increase in the applications of AI, it becomes a challenge for conventional computers to match the accuracy and speed.
Through quantum computing, it will take a matter of few seconds for AI to learn huge data.
Computational Chemistry #
According to IBM, one of the most pioneering applications of quantum computation will be in Chemistry.
The ability of quits to subsist in multiple states simultaneously will allow us to map the molecules successfully. This will open new areas of research in pharmaceuticals.
It will help create superconductors working at room temperatures and removing excess carbon dioxide from the environment. It will also improve the nitrogen-fixation process and create solid-state batteries used in pacemakers and wearable devices.
Medicine
Drugs are developed using the trial-and-error technique, which is very risky, tough, and costly.
Through quantum computing, the efficiency of designing and developing drugs will increase and the negative results will get eliminated. It will help understand the reactions of drugs on humans, saving resources, time, and reducing the risks. It will also permit drug companies to make discoveries and unveil new medical remedies, improving the healthcare of the globe.
Weather Forecasting #
Since the world is undergoing climate change, an effective weather forecasting system is vital. Conventional computing methods take time to analyze and predict weather conditions. Sometimes, during this process, the weather changes.
Quantum computing will enhance the predictions and improve the system. It will generate detailed climate models, predict dangerous weather events, and provide broader insight about ways to alleviate climate change.
Cybersecurity
With the rapid increase in caber-frauds, cybersecurity continues to be a major concern across the globe. Our dependency on digital systems is increasing, making us more vulnerable to these threats.
Establishing a secure framework with conventional computers is intimidating. Quantum computing will develop several methods to combat these threats and also create encryption, like quantum cryptography.
Supply Chain and Logistics #
Quantum computing will allow the optimization of supply chain and logistics through enhanced data analysis and robust modeling.
Solving logistics workflows and optimal routes with classical computers becomes complex. Quantum computing can calculate and recalculate traffic management and control, distribution, and supply-chain management.
How Do I Get Started with Quantum Computing? #
Here are a few things you will need to get started with quantum computing.
Curiosity
Although curiosity isn’t a piece of knowledge, it’s the most essential element if you wish to learn quantum computing from my perspective.
This is not limited to quantum computing. If you wish to get anywhere or learn anything, curiosity is essential. It is the basic reason for inventions, discoveries, and scientific advancements.
Programming
You will require programming basics to get started with quantum computing. Python is the most preferred language for quantum computing since it is used to program actual quantum machines.
You can also try programming a quantum machine through IBM’s open-source toolkit Qiskit.
Math
Math is used in several technical fields, from machine learning and AI to natural language processing. For quantum computing, you will need Linear Algebra and Probability Theory.
Physics
Properties like superpositions, entanglement, and interference are purely from Physics. So, to become a quantum developer, you will need to know the working of a quantum computer to use it for building your applications.
Mechanics and Physics are important if you aim to build and construct quantum computing hardware.
Final Notes #
Quantum computing will be the new way to harness nature. It will form major changes in our existence like understanding of the Big Bang Theory, spurring breakthroughs in medical care, and enhancing security framework.
Although we are enthusiastic about the quantum machine, a relevant machine will take decades to develop.
All the leading computing organizations, universities, and colleges are researching the topic. The current challenge is to observe and develop ways of controlling the quantum phenomenon.
The fancy notion is gaining acceptability. An exceptional evolution is in progress!
