Definition and things that need to be fixed

If you thought we were living in such a technological era, you were dead on but there’s still a long way to go. Recently, large companies have taken important steps that lead them to quantum computing with which they hope to revolutionize the world. Below, there are some applications given to C in various industry fields.

In a binary world where Math rules, quantum computers are like small digital versions of Albert Einstein that have electronic brains to complete tasks that, in the real world, would be impossible for ordinary computers to do.

One quantum computer is the IMB Q System One, which measures 3 meters and possesses 20 Qubits. This computer was first presented in 2019, and is currently being tested by large businesses and researchers.

What is Quantum Computing?

This branch of computer science aims to superpose matter and quantum entanglement in a totally different computation method that is a thousand times more advanced than the traditional one.

In theory, quantum computers have more storage capacity and are greater at solving operations like no other computer than the computers we have been using for years.

This generation of supercomputers uses quantum mechanics, which is a field of physics that studies atomic and subatomic particles. Quantum computers avail themselves of those principles to go beyond the limits of classic computers.

Although in practice, they still fail to solve some types of problems, it is evident that it is a long way to go for them to be improved. Today, lots of scientists who study these computers are looking to get rid of the tunnel effect that handicaps nano-metric scale programming.


While traditional computers use bits, quantum computing uses qubits, which are smaller particles. The system intends to overlap ones, zeros, and the rest of the revolving digits of the binary system.

The machine permits all-digit superposition coherence within the quantum system. Unlike bits, qubits can have more than one value at a time, not only one or zero.

This means that a qubit can be 1 or 0 at the same time. Such multiplicity of states makes it possible that around 10 billion operations can be made in one sitting. This is the equivalent to 5.8 more operations than the amount of what a Play Station 5 console can complete.


The main difference between quantum computers and conventional PCs is that the former use qubits and the other one run on bits. However, there are differences to be considered:

Programming language

Until now, quantum computers lack programming codes just like those that traditional computers use. Quantum computing requires custom programs to be able to operate. There are no such things like Python, SQL, and Java in quantum computing.

In the future of quantum computing development and algorithms is expected to be standardized to cut back on programming costs.


Quantum computers are not geared up for widespread everyday use yet these machines are too complex to be understood by a regular Joe. Because of this, these devices are exclusive to companies that work in the scientific and technological fields.


These computers need neither a memory card nor a processor. The equipment has only a set of qubits that do the whole job. On top of that, quantum computers are architecturally simpler than conventional ones.

Where do QUANTUM COMPUTERS operate?

These computers are more complicated than we may think, especially if we consider that they need to operate in specific conditions, pressure, and temperature. Quantum computers are actually very sensitive and can react to the surrounding things.

Because of this, they still have to be operated using conventional computers to delete mistakes that occur following the interaction with external particles. Errors in quantum computing are associated to data erasure and state overlaps.

Additionally, quantum computers have no atmospheric pressure and they must be installed in very cold ambient in freezing temperatures. Also, they cannot be influenced by magnetic fields, which can lead atoms to collide or interact.

Unlike traditional computers, they must work for short intervals to prevent information damage. Restoring data on a quantum computer can be challenging.

Industries are where quantum computing is used the most

Some of the fields that have started to use this technology are bio-medicine, computer security, and the economy. These are some benefits that quantum computing has provided to them:


Quantum computers are used to detect fraud and simulate systems, thus improving their investment portfolios.


This sector is becoming necessary in DNA research and the development of new drugs. It aims to find customized treatments for specific diseases.

Cyber Security

With this technique, companies detect intruders through very light signals. Using quantum computing for cyber security involves risks but can also assist in data encryption.

Mobility and transport

Airbus has started using quantum computing to design more innovative aircraft. Qubits have brought new route optimization and traffic planning systems.

Things that still need to be Improved

Quantum computing is not supercomputers; they actually go further than that. They are capable of solving problems that are not within the capacity of a supercomputer. Experts think quantum computers should be focusing on realizing more important goals rather than bragging about their capabilities.

Also, quantum computing must be given better usage in the huge Google platform. Something that concerns scientists is the correction of errors that are provoked by external factors.

It is true that quantum computing capabilities are no match with those of traditional PCs. But at least normal computers have no issue when they interact with their surroundings and can fix errors automatically.

If any error occurred on a quantum computer, it wouldn’t be corrected on the spot definitely. Nobody knows exactly to fix errors or overlaps caused by external factors. These studies are still in progress, anyway.

Also, scientists worry about making errors with computers that cost million of dollars. In the end, traditional supercomputers can make mistakes but they can be corrected without an enormous investment.

Normally, when information delivered by quantum computers comes out defective, erasing or fixing it is time-consuming and money-wasting.
