Quantum engineers from the University of California, Iowa State University, and Delft University of Technology in the Netherlands have built a quantum computer inside a diamond by exploiting the unsightly impurities in it. The flaws found in the crystalline structure of diamond became the soul of quantum computer in the shape of qubits.
Researchers used the nucleus of the diamond as one qubit and electron as the other qubit. When these two apposite qubits work together they lessen the deficiency of quantum computer of decoherency.
Quantum computer could perform much faster than digital computers as in ordinary computers bits means that information is rendered either in the form of one or zero, whereas elements in quantum computers render the same information much quickly due to performing the algorithm of one and zero simultaneously. Using the Grover`s algorithm the diamond computer could find correct entry at the first try.
Those elements working with ones and zeros at the same time had a major drawback, as being fast make them vulnerable to fall a victim to decoherence. To resolve this issue engineers used microwave pulses to change their direction to stop them from interacting from each other.
