3. INTRODUCTION
WHAT DOES QUANTAM MEAN?
The word "quantum", in quantum computer, originates from "quantum mechanics," a
basic theory in physics. In brief, on the scale of atoms and molecules, matter behaves
in a quantum manner.
WHAT IS QUANTAM COMPUTER?
A quantum computer is a machine that performs calculations based on the laws of
quantum mechanics, which is the behavior of particles at the sub-atomic

4. BASIC CONCEPT OF QUANTAM COMPUTER &
DIFFERENCE BETWEEN EXISTING COMPUTER:
• In existing computers, all information is expressed in terms of 0s and 1s, and the entity
that carries such information is called a "bit.“
• A bit can be in either a 0 or 1 state at any one moment in time.
• A quantum computer, on the other hand, uses a “quantum bit” or "qubit" instead of a bit.
• A qubit also makes use of two states (0 and 1) to hold information, but in contrast to a
bit, In this state, a qubit can take on the properties of 0 and 1 simultaneously at any one
moment.
• Accordingly, two qubits in this state can express the four values of 00, 01, 10, and 11
all at one time

6. CLASSICAL BIT VS QUBIT:
• Classical bit: {0, 1}
• Qubits: {0, 1, superposed states of 0 and 1}

 Entanglement is the ability of quantum systems to exhibit correlations
between states within a superposition.
 Quantum entanglement is one of the central principles of quantum
physics, though it is also highly misunderstood.
 In short, quantum entanglement means that multiple particles are linked
together in a way such that the measurement of one particle's quantum
state determines the possible quantum states of the other particles.
 When this happens, the state of the two particles is said to be entangled.

13. QUANTAM TELEPORATION
Quantum teleportation is a technique used to
transfer information on a quantum level, usually
from one particle to another.

14. ADVANTAGES:
• Could process massive amount of complex data.
• Ability to solve scientific and commercial problems.
• Process data in a much faster speed.
• Capability to convey more accurate answers.
• More can be computed in less time.
• These are used to protect secure Web pages, encrypted email and many other
types of data.

15. DISADVANTAGES AND PROBLEMS:
 Hard to control quantum particles
 Lots of heat
 Expensive
 Difficult to build
 Not suitable for word processing and email.
 Problem of it need of a noise free & Cool
Environment.
 Complex hardware schemes like
superconductors

16. CONCLUSION AND SCOPE
 Very Advance Technology
 Very Faster & Powerful
 Stage of Infancy
 Implementation is Difficult
