2. Quantum computers
Quantum computers
use atoms to
perform calculation
Here computation
depends on
principle of
quantum theory
Qubit

3. HISTORY
1982 - Feynman proposed the idea of
creating machines based on the laws of quantum
mechanics instead of the laws of classical physics.
1985 - David Deutsch developed the quantum
Turing machine, showing that quantum circuits are
universal.
 1994 - Peter Shor came up with a quantum
algorithm to factor very large numbers in polynomial time.
1997 - Lov Grover develops a quantum search
algorithm with O(√N) complexity

4. Why quantum computer
Moore’ law slowing down
in 2020 it is flattened
out.
Transistor cannot be
made smaller due to the laws
of Quantum mechanics
starts to take over
Post silicon era

5. What special about Quantum computer

6. APPLICATIONS
•Cryptography
•Artificial
intelligence
•Teleportation
•Quantum
communication

7. Problems
•Decoherence
•Error correction
•Output observance
•Cost

8. Conclusion
If we built this computer then it would
revolutionized our human society
