Quantum_computing[1].pptx

  1. 1. Welcome to the future of computers Quantum Computers
  2. 2. Processors  Processors are decreasing in size since they invented.  Transistor work as switch flow/stop current.  Small size benefit is low power consumption and high efficiency.  Transistor size is 14 nanometers.  In next few years by decreasing the size of transistor it will become small as an atom.
  3. 3.  Purpose of transistor will end because electron perform quantum tunnelling effect.  Then we need computers..
  4. 4. Quantum Physics  Solidity of matter is an illusion. atom  electron  quarks  wave  Nature laws breaks in quantum world.  Quantum entangled relationship.
  5. 5.  Physical duality (superposition state). Wave & particle Visible & invisible Solid & non-soid  Time is not real theory.  Double slit experiment.
  6. 6. Quantum Computers
  7. 7. Different from traditional computers. Traditional computers use binary digits ( 1 or 0). Quantum computer use quantum digits are qubits. Quantum computers use atoms for computation rather than computer chip.
  8. 8.  Atoms are always in motion up & down and both at the same time.  40 qubits  todays super computer.  Below 0celcius temperature and magnetic field is required to operate qubits.
  9. 9. Advantages  Medical  Agriculture  Climate change  Quantum teleportation & communication  Solve complex problem within second (50,000 qubits =many year of universe and google 3min 10 sec = 10,000 year demonstration)
  10. 10.  security • Race b/w nation to make quantum computer, its like space race. • To keep data safe of govt. , companies, millatry etc. • 2013 American Intelligence contractor adward snowden. • massage  encryption  send traditional computer  100’s year quantum computer  hrs or min.
  11. 11. Scope in quantum computing  Quantum information science & techonolgy (India 2018, 8000 crore rs.)  China 11 billion dollars, Europe 5 billion dollars, USA 3 billion dollars, U.K. 1.8 billion dollars.  Leading companies • IBM • Google Quantum AI • Zapata computing • Intel • Microprocessor
  12. 12. Thank you……
