  In this work, a constant time Quantum searching algorithm over a datasets is
proposed and subsequently the algorithm is executed in real chip quantum
computer developed by IBM Quantum experience (IBMQ). QISKit, the software
platform developed by IBM is used for this algorithm implementation. Quantum
interference, Quantum superposition and {\pi} phase shift of quantum state
applied for this constant time search algorithm. The proposed quantum algorithm
is executed in QISKit SDK local backend 'local_qasm_simulator', real chip
'ibmq_16_melbourne' and 'ibmqx4' IBMQ. Result also suggest that real chip
ibmq_16_melbourne is more quantum error or noise prone than ibmqx4.
