Computer Is Of Two Types
1] Classical Computer
2] Quantum Computer
1] Classical Computer -
8 bits = 1 byte
Types of bytes
1 byte
1024 kilobyte
1048576 megabyte
1073741824 gigabyte
1090511627776 terabyte
2] Quantum Computer -
quantum computer based on quantum physics theory. Instead of byte here <qbyte></qbyte> (q=quantum byte). Here byte 2.0 version is used.
Binary numbers can have the following possibilities - 1 0 1&0. Here quantum superposition theory is used.
In the case of a 2-qubit(quantum bit) system. There are two possibilities : 11 00 10 01
In this case, quantum entanglement is used. if there is 3-qubit then 16 possible states are available. As the qubit increased possible states are increased. However, classical computer cannot answer these qubits.
During the experiments, the quantum computer produces results in 3 minutes and 20 seconds while the classical computer does not respond in the same time. A quantum computer performing task 100 trillion faster than the world fastest computer. A quantum computer is superior then any other computer. Also, A bit quantum computer store more amplitude than there are atoms in the universe. A quantum computer can be placed in 0 degree celsius.
Disadvantage of quantum computer is - As it is a highly superior computer, it can open any security lock. therefore scientist are making cyber free computer.
