6. Bits (classical computing)
A bit can exist only in one
state
Either 0 or 1
Information behaviour : one
single direction
Logic gates are irreversible

7. Bloch Sphere representation of a QBIT
a two-state quantum-mechanical system
Can exist as 0 or 1 or
coherent superposition of
both
Operation on a qubit
effectively acts on both
values at a same time
An exist in both values
simultaneously

10. Processors
Classical processors
Each processor perform one
computation,while other
processors do other
computations
Quantum processors
Single processor can
perform multiple
computations on its own
simultaneously

12. One day, a 2^500 qubit computer will be able to
calculate more data than there's atom in our
observable universe
13. Representation of Data -
Superposition
A single qubit can be forced into a superposition
of the two states denoted by the addition of the
state vectors:
|ψ> = α |0> + α |1>
Where α and α are complex numbers and |α |
+ | α | = 1

Use direct use of quantum mechanical
phenomena
Utilizes quantum properties to represent data
Could solve certain problems much faster

19. ● In 1981, German Mathematician Yuri Manin first introduced the idea of Quantum
computers
● A year later, eminent physicist Richard Faynmann presented a logical model at the
conference on physics and computerization but his model rested in the conviction
that it would be impossible to simulate the calculations through a classical computer
● But Faynman's lectures from the last years of his scientific research is now
considered by many to be the key moments
