Quantum computation is a field that leverages the concept of quantum physics to revolutionize computing capabilities. Quantum bits, or qubits, are used in quantum computing and have the superposition property, which allows them to exist in several states at once. This ability to be in superposition allows quantum computers to perform computations in parallel, exponentially increasing their computational power compared to classical computers for certain types of problems. In this paper, the design and simulation of basic quantum gates like CNOT and CCNOT are done using an elementary quantum server. The best design with the highest percentage of results is reported after a comparison between the simulation results and the actual backend findings from the IBM quantum experience. Ideal and noisy circumstances are considered for experimental settings. The mitigation effects of measurement error are also investigated for both reversible gates, and the improvements are summarised.
