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

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI  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

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI 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.

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI Comparison between Classical & Quantum Computing

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI 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.

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI Behavior of Quantum Computer based on prototype desktop computer

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI Quantum Computing uses the followings  Quantum parallelism  Entanglement  Josephson junction

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI Quantum Gates

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI Quantum Gates

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI Quantum Gates

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

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI Quantum Teleportation

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

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

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI 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.

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI Next to Quantum Computing  Nanomachines  DNA Computing

TECHNICAL SEMINAR Quantum Computing PRAVAT KUMAR NAYAK EI 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.
