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.
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 0celcius 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

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.
