Quantum computers

• Quantum computers use atoms to perform calculation

• Here computation depends on principle of quantum theory

• Qubit

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 - LovGrover develops a quantum search algorithm with O(√N) complexity

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

What special about Quantum computer

APPLICATIONS

• Cryptography

• Artificial intelligence

• Teleportation

• Quantum communication 

Problems

• Decoherence

• Error correction

• Output observance

• Cost

Conclusion

• If we built this computer then it would revolutionized our human society
