Quantum Computing ppt

This seminar presentation provides an introduction to quantum computing, including its history, why it is important, how it works, potential applications, challenges, and conclusions. Specifically, it discusses how quantum computers use quantum mechanics principles like qubits and superposition to perform calculations. The history includes early proposals in 1982 and key algorithms developed in the 1990s. Applications that could benefit from quantum computing are mentioned like cryptography, artificial intelligence, and communication. Issues like error correction, decoherence, and cost are also presented. In conclusion, quantum computers may be able to simulate physical systems and even develop artificial intelligence.

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 - Lov Grover 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 A quantum computer thus has the theoretical capability of simulating any finite physical system and may even hold the key to creating an artificially intelligent computer.
