- 3. INTRODUCTION TO QUANTUM COMPUTING • Rapidly emerging technology that harnesses the law of quantum mechanics to solve problems too complex for classical computers • quantum mechanics is a sub field of physics • It describes the behaviour of - atoms,electrons,photons , and almost everything in the molecular and sub molecular realm • Fundamentally different way of processing information compared to today’s classical computing systems 3
- 4. DIFFERNT FROM TRADITIONAL COMPUTERS Classical computers stores information as 0 and 1 quantum computers draw on the fundamental laws of nature to carry out calculation using quantum bit qubit can be in a combination of states which allow for exponentially larger calculations potential to solve complex problems which even the most powerful classical super computer are not capable of. 4
- 5. SOME PRINCIPLE IN QUANTUM COMPUTERING Superposition:- they can exist in multiple states (both 0,1) at same time. it is unlike classical computers where information is processed in bits or 1s and 0s following classical physics entanglement:-where two or more particle are inextricably linked and mirror each other exactly ,even when separated by great physical distance 2022 Nobel Prize in physics 5

- 8. CHALLENGES AND LIMITATIONS • Higly prone to interference that lead to errors in quantum algorithms running on it • most quantum computers cannot function without being supercooled to a little above absolute zero • Acute shortage of candidates with doctorates in quantum engineering and statistics • India lacks the capability to domestically manfacture most of the components/ hardware. 8
- 9. KEY INITIATIVES TAKEN BY GOVERNMENT OF INDIA • National Mission on quantum technologies and applications: • The Government in its 2021 budget allocated INR 8000 Crore towards the National Mission on quantum technologies and applications to spur developments in quantum computing, cryptography, communications, and material science. Quantum Computing Laboratory: 9
- 10. ADVANTAGES AND DISADVANTAGE • The main advantage of quantum computing is that it is even classical algorithm calculations. They are also performed easily which is similar to the classical computer. • If we adding the qubits to the register we increase its storage capacity exponentially. • In this computing qubit is the conventional superposition state. So there are advantages of exponential speedup to the resulted by handle the number of calculations and method. • Quantum computing required less power. • The research for this problem is still continuing the effort applied to identify a solution for this problem that has no positive progress. • Qubits are not digital bits of the day thus they cannot use as conventional error correction. • The main disadvantage of Quantum computing is the technology required to implement a quantum computer is not available at present days. • The minimum energy requirement for quantum logical operations is five times that of classical computers. 10
- 11. Way forward • The need of the hour, therefore, is simultaneously to build sufficient quantum computational capacity, develop skills in building and operationalizing a practical size and affordable cost quantum computer, continue research into realizing the various practical applications, and introduce contents into the educational courses at undergrad and post-grad levels to develop quantum science and engineering as a discipline at the university level that will produce a large number of science and technology heads. 11
