What is Quantum Computing?

Quantum Computing

Classical computers are getting more and more advanced, both Intel and AMD are pushing the Processor Capabilities to the limit with each passing year.

However, these processors and advancements only fall short within the boundaries of Binary calculation between 0 and 1. This raised a question that computational abilities will become inferior in comparison to the demands of required processing power. This Pushed the Researchers to look beyond this 0 and 1 and look for a new type of computational procedure and thus gave birth to quantum computing.

What is Quantum Computing?

Quantum Computing is a type of computer that uses quantum mechanics(computation at atomic or subatomic levels) to perform calculations.

Classical computers use transistors to perform Computations and more complex equations require heavy burden on transistors to solve the data in 0 and 1 binary bit data. Classical computers even with technological advancements can run data in a sequential manner either in the form of 0 or 1.

Quantum Computing uses quantum bits(qubits) instead of bits like classical computers. This removes the need for doing a singular process at a time and opens the space for multiple processes at a time. Quantum Computers can perform computations million times better than the current generation classical computers.

Quantum computers are also more energy efficient than Classical Computers.

For Example, Imagine a sphere a bit can be at either of the two poles or points at a sphere but a qubit can exist at any point on the sphere. The limitations of bit processing don’t apply to Quantum Computing and heavy computations can be completed in a short neck of time.

Current Situation on Quantum Computing

Google, IBM, and many other Tech giants are pushing for improvements in the field of Quantum Computing. So, far none of them have been able to construct a fully functional Quantum Computer.

Google was pushing for quantum computers for a while and in 2017 Google announced that they were able to create a 49-qubit quantum computer calling it ‘quantum supremacy’. However, this success was short lived and IBM topped it with announcing they built a 50-qubit quantum computer. This system is also quite unstable and this system was only been able to hold the quantum microstate for 90 microseconds. This was a record but far below the required time for quantum computers to be called as practically viable.

The benefit of Quantum Computers over Regular Computers

In this era of Digitisation, Cryptography is required to secure internet usage. Cryptography requires computations of prime numbers which is a slow process for traditional computers but with the help of Quantum computers the processing rate will be much higher and security of websites can be further optimized with ease.

Supercomputers don’t really shine when modeling complicated chemical reactions. This requires heavy processing capabilities that even supercomputers fail to do so. Scientists believe with the help of Quantum computers designing complex molecules. This Modelling will help the researchers to design new molecules for use in medicine.

We are just scratching on the Scope in different fields using Quantum computing and if Google and IBM deliver on their promises on building a Functional Quantum computer, this will revolutionize the world as computers did in previous years.
