Quantum Computing: A Revolution in Computing

At first, it all started with an idea of making the world digital and now we are blessed with revolutionary technologies like AI, 3D printing, Blockchain, and a lot more. As the requirement of the organizations is getting bigger and bigger in making better strategies and analytics for their business, new technologies are being invented and quantum computing is one of them.

A few years ago, IBM made a quantum computer of 5 quantum bit (qubit) which is known by a name the IBM Q experience. After that, big companies like Intel and Google also started working on the quantum computing and promised to come up with a better quantum computer of 50 qubits. The next goal in the field of quantum computing is to attain quantum supremacy, in which quantum computers can carry out operations which could not be done by classical super computers. Recently, researchers at the Google announced that they will demonstrate the quantum supremacy by the end of the year.

Quantum systems may unscramble the complexity of molecular and chemical interactions which could lead to a revolution in medicines. They may also help in effective logistics and supply chain, such as optimizing the operations during the delivery of product in the holiday seasons. With the help of it, we can have new models of financial data and isolate the risk factors to make a better investment. Other than business purposes, it is also useful for making the security unbreakable. The integer factorization, on the basis of which security of public key cryptographic systems is made, is not possible with the classical computers whereas Quantum computers can solve this problem using Shor's algorithm to find factors. This property of quantum computing allows breaking many cryptographic systems that could be used in the protection of Web pages, encrypted email, and many other types of data.

Today, the Quantum computing is at its initial stage and there are much-unsolved mysteries in the quantum theories that are yet to be discovered. “I think we have definitely reached an inflection point where there is now real hardware available and also significant interest in quantum computing from industry; this means that development will now accelerate at a tremendous rate,” says Zapata’s CEO Christopher Savoie.
