2. OVER VIEW
 Introduction
 How It Works?
 Advantages
 Challenges
 Future

3. What is quantum computing?
 Use of quantum mechanics to perform
computational operations
 Operations are done at atomic level
 Uses properties like Quantum
superposition, Quantum entanglement, Uncertainty
principle, Wave interference

4. The Bloch sphere
 Bloch sphere is a
representation of
qubit, the fundamental
building block

5. Why quantum computing?

6. how it works?
 Use of qu bits
 This superposition of states is what makes
quantum computing fundamentally different.
 parallelism

8. Advantages
 Can increase the processing speed
 Secure
 Effective communication

9. Challenges
 De coherance
 Error correction
 Output observability
 Cost

10. Where we are?
 A 2-bit quantum computer has been made
from a thimble of chloroform; its input
consists of radio frequency pulses into the
liquid containing, in essence, the compiled
program to be executed.
 In 2011, D-Wave launched a fully-
commercial, 128-qubit quantum computer
 D-wave is working with google to develop
quantum computing algorithms for image
recognition purposes

11. Future
 It will be the promising technology that
meets the growing needs of speed.
 It will tackle with the problems that a
conventional computer can not .
