  1. 1. By, ROLLNO : ECE ENGG. COLLEGE
  2. 2. LIST OF CONTENT Introduction Quantum & development of quantum theory Basic concept of quantum computer Applications Advantages Difficulties Future work Conclusion
  3. 3. INTRODUCTION 1980, development of a quantum computer was started 1,000,000,000 times faster Theoretically -no energy consumption Feynman, 1982 Bit &Qubits
  4. 4. QUANTUM & DEVELOPMENT OF QUANTUM THEORYQuantum smallest possible discrete unit of any physical property
  5. 5. QUANTUM THEORY Quantum mechanics lights duality James C. Maxwell(E M wave) photoelectric effect Schrödinger Equation
  6. 6. BASIC CONCEPT OF QUANTUM COMPUTERSuperpositioning overlap each other without interfering with each other.
  7. 7. + β
  8. 8.  If this state is measured, we see only one or the other state (live or dead) with some probability.Quantum Turing machine simple model Express any quantum algorithm
  9. 9. Qubits The unit of quantum information is the quantum bit or qubit
  10. 10. Quantum teleportation Transmission of q bit quantum information processingQuantum gates act on qubits and quantum registers change their states – rotating state vectors
  11. 11. Quantum register more than one qubits multi-dimensionalQuantum computing circuit model Input- quantum register-computation-result
  12. 12. Quantum computer working not limited by the binary nature qubit-1 or 0 – combination- any number –decimal NMR change the states Difficult to hold in steady state Separate atoms 2-5 atoms
  13. 13. D-wave quantum computer
  14. 14. APPLICATIONEncryption Technology Ultra-secure and Super-dense Communications Improved Error Correction and Error Detection Molecular Simulations True Randomness
  15. 15.  cryptography searching factorization simulating encryption problem & quantum chemistry problem
  16. 16. ADVANTAGES Much more powerful Faster Smaller Improvements to science Can improve on practical personal electronics
  17. 17. DIFFICULTIES Hard to control quantum particles Lots of heat Expensive Difficult to build Not enough is known about quantum mechanics
  18. 18. FUTURE WORK Silicon Quantum Computer It may become technology sooner than we expect New algorithms and communication Maximum exploitation Simulate other quantum systems.
  19. 19. CONCLUSION very advance technology very faster & powerful Stage of infancy Implementation is difficult
