The quantum computing have quantum bits, which stores, and processes information at any point of the system.
With the world already taking a leap towards the technological advancements, the IT industry is also looking for options, that would render in easy and fast processing of information. As a huge amount of data is generated every day, the need for efficient computing process is recognized amongst the industry, so that the processing can be conducted faster, without any loophole in the generated results. Hence, tech leaders are exploring new solutions with the help of quantum computing, that stores large amount of data, thus requiring less energy for the process of the information.
Understanding Quantum Computing
Quantum Computing is still at the nascent stage, but its need has been realized at a very early stage by the IT industry. The reason being that as the world is moving forward, leaders are able to take cognizance of saving the sustainable energy. A report by the Semiconductor Industry Association, states that by the year 2040, the world will lose the capability to power all the machines in the world. As a classical computer heavily rely on the electricity and power, with such possibility, their functioning will be challenged.
Unlike, a classical computer, which are governed by binary system of bits i.e. 0 and 1, to process information, the quantum computing have quantum bits, which stores, and processes information at any point of the system, thus utilizing less energy than that of classical computers.
Properties of Quantum Computing
Quantum Mechanics already garnered attention in the 1980’s, but the idea of quantum computing briefly gained momentum in 1994, when a mathematician Peter Shor developed quantum Algorithm, for finding prime factors of large numbers efficiently.
Quantum computing has two attributes that makes this technology differential from the classical computing process. They are Superposition and Entanglement. Recently, interference has also been added as one of its major properties, but scientists are more curious to know about the former attributes of quantum computing.
Superposition, in layman language, is the existence of a quantum object like electron in a multiple state, say upper and lower energy levels, thus demanding lesser energy in the first excited level. With the help of Superpositioning any quantum object, the information in quantum computing can be retained using Qubits. Unlike the classical computing which are governed by the bits as transistors, and corresponds to the states 0 and 1, the quantum computing have qubits which corresponds to upper and lower energy, and has the ability for superpositioning different objects with varying probabilities for manipulating the quantum operations during computations.
Entanglement refers to the creation of quantum entities or objects, by manipulating such that the explanation of one entity is not possible without referencing the others. This will increase the probability of having a correct output as compared to that of Classical computing.
Quantum computing, thus leverages the entanglements by the qubits and the probability with the superposition, to carry out a series of operations with the help of quantum algorithms, so that the chances of the correct answers will have more pros than that of the wrong answers.
Countries Fighting Quantum Supremacy
Every computer is hollering in the race of quantum supremacy. While the USA has invested a fund of US$1.2 billion for National Quantum Initiative Act (NQI), for the research on quantum computing in the next five years, China has already funded a multi-billion dollar quantum computing mega project for achieving a quantum breakthrough by the year 2030. A Chinese National Laboratory for Quantum Information sciences has already been established, which has the probability of becoming a global hub for quantum research.
The country of IT professionals, India, has also announced investment worth Rs.8000 crore, for the research in quantum computing over the period of next five years. The country is also planning to start a program called National Mission on Quantum Technologies and Applications.
With such a huge investment, India’s Finance Minister Nirmala Sitharaman, remained optimistic, for utilizing quantum computing in the near future. She said, “Quantum Technology is opening up new frontiers in computing, communications, cybersecurity, with widespread applications. It is expected that lots of commercial applications would emerge from theoretical constructs which are developing in this area.”
Owing to this huge investment, the governments’ Department of Science and Technology are already drafting the outlines of a mission, that would help them in building native 50 Qubit Quantum Computer over the period of next five years.
Big Techs Racing With Quantum Computing
Just like emerging countries, big techs are also rushing for making a technological breakthrough with quantum computing. Google last year built a quantum processor called Sycamore, which solved the sampled calculation in three minutes and 20 seconds. Owing to its success, Google said, that today’s most powerful computer would require about 1000 years solving the problem. With its reference to IBM’s supercomputer, IBM rejected Google’s claims, citing it as mere Skepticism on Google’s part.
However, the race is not limited to Google and IBM, other big tech companies like Microsoft, and Accenture are also observing reformation with Quantum computing.
Accenture’s Senior MD Marc Carrel-Billiard, in an interview said, “While this disruptive technology is still in its infancy, its advancing quickly and organizations should be thinking seriously about what it means for their industry and their company. Early adopters will have a significant edge over those who take a wait and see approach.”
Thus it is suffice to say that with the race over technological supremacy, no country or organization is willing to get their hands off from laying in quantum computing. Since the technology is still in a nascent stage, and evolving, apart from the applications, it will have its own challenges, that the world needs to be prepared about. Undoubtedly, the sectors like healthcare, cybersecurity, defense, will be revolutionised by quantum computing. But at the same time no organization knows the loophole associated with quantum computing.
The world just needs to watch out, what it is looking for with quantum computing!
