Quantum computing is a computation system to perform operations on data by using the direct mechanism of quantum theory phenomena like superposition and entanglement. The system is also known as quantum computers.
Quantum Mechanics is mainly for speed computation and quantum computers which tap directly without imaginably vast fabric of reality that is an unfamiliar and counterintuitive world of quantum mechanics.
Based on Transistor, Quantum computers are different from binary digital electronic computers. A Quantum Turing machine is a theoretical model of some standard computer. This type of computer is in common digital computing methods which require the data be encoded into binary digits, quantum computation uses quantum bits, each of which is always in one of two definite states (0 or 1) which can be in superpositions of states. This operating system is also known as the universal quantum computer.
Principles of Operation
A quantum computer is different from a standard computer with a given number of qubits that composed with the same number of classical bits. A standard computer has a memory made up of bits, which is represented by either a one or a zero. A quantum computer controls a sequence of qubits like one, two, three qubits.
A single qubit can represent a one, and also any quantum superposition of those double qubit states a pair of qubits can be in any quantum superposition of 4 states, and third qubits in any superposition of remaining eight states.
In general, a quantum computer with the number of qubits that can be in an arbitrary superposition of up to different states together and this compares to a classical computer that can only be in one of these states at any one time.
A quantum computer operates by arranging the qubits in a correct drift that describes the problem at hand and by managing those qubits with a fixed sequence of quantum logic gates. The series of gates to be implemented is called a quantum algorithm. The calculation ends with a measurement and collapsing the system of qubits into one of the pure states that decompose into a classical state.
