Abstract

Following experimental work [Nature , 473, 194 (2011) [CrossRef]  ], we propose a new physical scheme for perfect implementation of a quantum search algorithm in the presence of qubits dissipation. It is shown that the Grover algorithm is obtained as a special case of the suggested quantum search algorithm. We have generated the quantum gates to realize the required steps for implementing the algorithm. Experimental evidence has been discussed in which, during a critical portion of quantum annealing, the qubits become entangled, and entanglement persists even as these systems reach equilibrium with a thermal environment. Our results provide an encouraging sign that quantum annealing is a viable technology for large-scale quantum computing. It is shown that the protocol can be successfully implemented within the present experimental limits.
