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
APPLICATIONS Cryptography Artificial intelligence Teleportation Quantum communication
Advantages Faster computations:- These type of computers can perform computation at a much faster rate than normal computers. Quantum computers have computation power higher than supercomputers also. They can process data at 1000 times faster than normal computers and supercomputers. Some calculations if performed by a normal computer can take 1000 years is done by quantum computers in a few seconds. Best for simulation:- Quantum computers are best for doing data simulation computing. There are many algorithms created that can simulate various things like weather forecasting, chemical simulation etc.
Advantages Contt. Medicine creation:- These type of computers can work better in the medical field. They can detect diseases and can create a formula for medicines. Different type of diseases can be diagnosed and tested in scientific laboratories using these computers. Google search:- Quantum computers are used by Google to refine searches. Now every search on Google can speed up by using these computers. Most relevant results can be populated using quantum computing. High privacy:- These computers can make high encryption and is good at cryptography. It is impossible to break the security of quantum computers. Recently China has launched a satellite that uses quantum computing and china claimed that this satellite cannot be hacked.
Disadvantages Algorithm creation:- For every type of computation, it needs to write a new algorithm. Quantum computers cannot work as classical computers, they need special algorithms to perform tasks in their environment. The low temperature needed:- As the processing in these computers is done very deeply so it needs a temperature of negative 460 degrees F. This is the lowest temperature of the universe and it is very difficult to maintain that temperature. Not open for public:- Due to the high range price they are not available for public use. Also, the errors in these type of computers are high because they are still in the development phase. Quantum computers work fine in 10 qubits but after increasing qubits like 70 qubits, the accuracy is not right.
Conclusion Quantum computers have the potential to revolutionize computation by making certain types of classically intractable problems solvable. While no quantum computer is yet sophisticated enough to carry out calculations that a classical computer can't, great progress is under way.
