1. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 TECHNICAL SEMINAR Presented by PRAVAT KUMAR NAYAK EI200118277 Under the guidance of Dr. SUKANTA TRIPATHY

2. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277  Now a days firms are continuing to expand the role of IT within their corporations and demand computers that are able to handle more complex solutions  Present Computers have some physical limits.  To overcome these limitations Futurists proposed two alternatives (i) Optical Computing (ii)Quantum Computing INTRODUCTION

3. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Why Quantum Computing?  Moore’s law  Optical Computing can increase the computation speed 1000 to 100,000 times faster than 1.2 GHz processors.  But optical computers for complex calculation will be greater in size than quantum computers  Hence quantum computing is the solution with minimum size & processing speed same as optical computing.

4. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Comparison between Classical & Quantum Computing

5. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 How does Quantum Computing Work?  Quantum computing uses atoms in place of traditional processors.  It uses Qubits, which can represent 0,1 & any value in between them at the same time.  A Quantum two bit can represent any of the numbers 00,01,10 & 11 simultaneously.

6. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Behavior of Quantum Computer based on prototype desktop computer

7. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Quantum Computing uses the followings  Quantum parallelism  Entanglement  Josephson junction

8. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Quantum Gates

9. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Quantum Gates

10. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Quantum Gates

11. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277  Quantum Computation:Increase the Computing Power  Quantum Cryptology: Advances in Security  Quantum Teleportation Projected benefits of Quantum Computing

12. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Quantum Teleportation

13. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Problems with Quantum Computing  Decoherence  Programming is Hard  Proving an operation unitary is difficult

14. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Projected risks of Quantum Computing  Uneven Distribution of adoption of new technology  Developmental discontinuity

15. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Developments  More than three decades ago IBM fellow Rolf landauer, first put the theory of Quantum information.  A decade later, Davi Deutsch & other research fellows proposed the concept of Quantum computing.  Currently, IBM has a 3-bit Quantum computer, while Alamos National Lab announced a 7-bit NMR computer.  IBM research fellows promised that a 10-bit computer will emerge soon.

16. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Next to Quantum Computing  Nanomachines  DNA Computing

17. TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI200118277 Conclusion  Hence Quantum Computing will be fast.  Size will be very small.  Processing & Security of the data will be enhanced & will be much better than present day computers.
