Finally, upon termination of the algorithm, the result needs to be read off. In the case of a classical computer, we sample from the probability distribution on the three-bit register to obtain one definite three-bit string, say 000. Quantum mechanically, we measure the three-qubit state, which is equivalent to collapsing the quantum state down to...

A type of computer that exploits uniquely quantum mechanical phenomena, such as superposition and entanglement, to process data. In a classical (or conventional) computer, data is handled in the form of binary digits, or bits; in a quantum computer, the unit of data is the qubit. Quantum computers m...
