This work tests the performance of Grover search circuits on the available IBM superconducting quantum devices that are accessible on the IBMQ cloud. Ideally, we expect to get a probability distribution that is clearly peaked at the targeted state. However, the quantum circuit executed on NISQ devices is vulnerable to noise which leads to fluctuations in the expected results. This depends on the quality of the device which is defined by a Quantum Volume parameter and on the depth of the circuit. Some previous works reached results that are completely noisy with no useful information, see for example Ref. [1] for 4 qubits (16 elements). Here we show that suitable implementations on concurrent IBMQ devices can actually yield useful results and explore the limitations.
