This is about the Quantum computing . This is a new technology .

1. Welcome to the future
of computers
Quantum
Computers

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.  Purpose of transistor will end because electron
perform quantum tunnelling effect.
 Then we need computers..

4. Quantum Physics
 Solidity of matter is an illusion.
atom  electron  quarks  wave
 Nature laws breaks in quantum world.
 Quantum entangled relationship.

5.  Physical duality (superposition state).
Wave & particle
Visible & invisible
Solid & non-soid
 Time is not real theory.
 Double slit experiment.

6. Quantum Computers

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.  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. 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.  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. 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. Thank
you……
