With the evolution in the technological age, we can only expect more to happen. In recent years, we’ve seen large companies taking little steps toward quantum computing, which will revolutionize the world. The functional areas of a quantum computer are vast as they will impact several areas, including healthcare and mobility.
We live in a binary world, comprising ones and zeros. Quantum computer is an aspect of computer science that is based on the principles of the superposition of quantum entanglement and matter. It uses different computational methods from traditional computers.
The new supercomputer uses quantum mechanics. Quantum mechanics is an area of physics that deals with studying both atomic and subatomic particles. Although quantum computing faces severe problems regarding incoherence and scalability, it is possible to do several immediate operations and eradicate the tunnel effect, which confines scale programming.
Quantum computing utilizes a qubit as the fundamental information unit instead of a conventional bit. An exciting feature of quantum computing is that it allows the coherent superposition of ones and zeros. Unlike traditional computing, where it is either zero or one, which is different for quantum computing as it can be both zero and one simultaneously.
Quantum Computing vs. Traditional Computing
In the computing world, quantum computing and traditional computing are parallel but possess similarities. In addition, it uses qubits instead of bits. I will look at the most significant differences between these two computing systems to make it easier. However, quantum computing is still in the research stage, and more development is needed.
- Programming Language – here, quantum computing lacks its programming code and needs the development and implementation of critical algorithms. Nevertheless, traditional computing comes to possess standardized languages such as Python, SQL, and Java.
- Functionality – Quantum computers aren’t designed for widespread and everyday usage in terms of functionality.
- Architecture – Compared to conventional computers, quantum computers have simple architecture. The equipment comprises a set of qubits that enables it to run.
Applicable areas of Quantum Computing
From stimulating to predicting the stock market, quantum computing will revolutionize businesses in all aspects. There are several application areas of quantum computing, and I will share a few of these use cases that companies are exploring.
Finding new drugs
To find new drugs, we rely on the science breach known as molecular simulation, which comprises modeling how particles interact within a molecule. These interactions are quite complex and can take different forms and shapes, meaning accurately predicting the shape and forms will depend on the structure as it will take a lot of calculations.
Besides this, the size of the current problem would be too large for a classical computer to handle. Because of this, it takes a long process to discover new drugs. Scientists usually use a trial and error approach. Nevertheless, a quantum computer can solve the problem of molecular simulation in minutes.
Another predictable area of quantum computing is in predicting the weather. Notwithstanding the large amount of computing power we have today, we still have inaccurate weather forecasts. The reason behind this remains that our current computer system cannot ingest all the data required to get an accurate prediction.
However, quantum computing can stimulate every particle interaction taking place in a molecule while predicting its behavior. Since quantum computers can analyze virtually all relevant data once, they can generate predictions faster than the weather forecast. This becomes useful as anyone can use the information to plan for their day or prepare for natural disasters.
Optimizing traffic signal time can help reduce the inflow of vehicles while minimizing congestion, especially at busy intersections. Our traditional computers find it hard to deal with this current problem because the more variable the system has, the more the possibility to be computed.
However, quantum computers can access multiple traffic scenarios simultaneously and produce the best outcome promptly. Currently, Microsoft is working on this project with Jij and Toyota Tsusho. Researchers have already started with the algorithms to create a simulated city to reduce traffic congestion.
Protection of Sensitive Data
Modern cryptography depends on algorithm-generated keys to encode data. Therefore, only individuals or parties with access to the key can have the means of decrypting the message. However, it comes with a two-fold risk for the traditional system. Firstly, hackers can intercept the key or use powerful computers to predict the keys the algorithm generates.
It’s possible for this to happen since security algorithms can be determined. However, quantum computing makes it harder for hackers to intercept such keys since they are randomly generated. One application of quantum computing is random number generation. We can build stronger cryptography keys that are harder for hackers to intercept.
